AXIS 211W - Product Features
Product Features
AXIS 211W is a professional wireless network camera capable of simultaneous Motion JPEG and MPEG-4
streams in full VGA resolution at up to 30 frames per second. It uses a progressive scan sensor, which drastically
reduces motion blur compared to traditional NTSC/PAL cameras providing interlaced video. When connected to
a fixed network it can be powered using Power over Ethernet (PoE).
AXIS 211W has advanced security and network management facilities both in fixed and wireless network mode.
In wireless mode it has full support for both Wired Equivalent Privacy (WEP) and Wi-FI Protected Access
(WPA/WPA2) making it one of the most secure wireless network cameras on the market.
The removable antenna gives a more flexible solutin that enables the use of a directional antenna indoors or
allows for installation of the AXIS 211W in an outdoor housing with an external antenna.

How to stream MPEG-4
This video compression standard makes good use of bandwidth, and can provide DVD-quality video streams at
less than 1 Mbit/s. Note that the image settings of the MPEG-4 stream are the same for all clients.
Deciding on the combination of protocols and methods to use depends on your viewing requirements, and on
the properties of your network. The available options in AMC are:
Unicast RTP
This unicast method (RTP over UDP) should be your
first consideration for live video when using Unicast,
especially when it is important to always have an
up-to-date video stream, even if some images are
This unicast method (RTP tunneled over RTSP) is useful as it is relatively simple to configure firewalls to
allow RTSP traffic.
RTP over RTSP over HTTP
This unicast method can be used to traverse firewalls.
Firewalls are commonly configured to allow the HTTP
protocol, thus allowing RTP to be tunneled.
Multicast RTP
This multicast method (RTP over UDP) should be your
first consideration for live video when using Multicast,
especially when it is important to always have an
up-to-date video stream, even if some images are
Unicasting is used for video-on-demand
broadcasting, so that there is no video traffic on the network until a client connects
and requests the stream.
Note: There is a maximum of 20 simultaneous viewers.
Multicasting provides the most efficient
usage of bandwidth, especially when there
are large numbers of clients viewing simultaneously. Note however, that a multicast
broadcast cannot pass a network router
unless the router is configured to allow this.
It is thus not possible to multicast over, e.g.
the Internet.
AMC will negotiate with the camera to determine exactly which transport protocol to use in the order listed
above. This order can be changed and the options disabled, to suit any specific requirements.
MPEG-4 is licensed technology. The AXIS 211W includes one viewing client license. Installing additional
unlicensed copies of the viewing client is prohibited. To purchase additional licenses, contact your Axis

• rtsp://<ip>/mpeg4/media.amp
• rtsp://<ip>/mpeg4/media.3gp
Notes: • The AXIS 211W supports QuickTime 6.5.1 (or later) and Real Player 10.5 (or later)
• QuickTime adds latency to the video and audio stream (up to 3 seconds)
• It may be possible to use other players to view the MPEG-4 stream using the paths above, although this is not guaranteed by
Axis Communications AB
Motion JPEG
This format uses standard JPEG still images for the video stream. These images are then displayed and updated
at a rate sufficient to create a stream that shows constantly updated motion.
The Motion JPEG stream uses considerable amounts of bandwidth, but provides excellent image quality and
access to each and every individual image contained in the stream. The recommended method of accessing
Motion JPEG live video from the AXIS 211W is to use the AXIS Media Control (AMC) in Microsoft Internet
Explorer in Windows. Note also that multiple clients accessing Motion JPEG streams can use different image
Alternative methods of accessing the video stream
Video/images from the AXIS 211W can also be accessed in the following ways:
• Motion JPEG server push (if supported by the client, e.g. Firefox). This option maintains an open HTTP connection to the browser and sends data as and when required, for as long as required.
• Still JPEG images in a browser. Enter, e.g. the path: http://<ip>/axis-cgi/jpg/image.cgi?resolution=320x240
• Windows Media Player. This requires AMC and the MPEG-4 viewing client to be installed. The paths that can
be used are listed below in the order of preference.
• Unicast via RTP: axrtpu://<ip>/mpeg4/media.amp
• Unicast via RTSP: axrtsp://<ip>/mpeg4/media.amp
• Unicast via RTSP, tunneled via HTTP: axrtsphttp://<ip>/mpeg4/media.amp

and exposure control. DC-Iris should always be enabled, except when focusing, or when using a non-DC-Iris
Please see the online help for further information on these settings.
Low Light Behavior
Low light conditions can reduce image quality and increase bandwidth usage. The Low Light Behavior settings
define the balance between image quality and frame rate. During low light conditions, experiment with the
settings Exposure priority, Max exposure time and Max gain until you achieve an acceptable image quality at
the required frame rate.
Exposure priority defines the balance between image quality and the frame rate. Higher image quality may
reduce frame rate and increase motion blur. A prioritized frame rate may instead increase image noise.
By increasing the Max exposure time the quality of the image will increase, but the frame rate will decrease.
There may also be an increase of motion blur.
AXIS 211W - Video and Image settings
Max gain, measured in decibels (dB), describes the amount of amplification applied to the visual information in
the image. A high level of amplification will provide viewable images in very low light, but will increase image
To prioritize image quality, choose Prioritize image quality from the drop-down box Exposure priority, and
lower the Max gain. If this does not produce the desired results, increase the Max exposure time.
To instead prioritize frame rate, choose Prioritize frame rate from the drop-down box Exposure priority and
reduce the Max exposure time to e.g. 1/25s or 1/30s. The image will darken considerably, but the frame rate
will be maintained. To increase the image brightness increase the Max gain, but this will also increase the
amount of image noise.
Please refer to the online help for more information
Advanced - MPEG-4 Settings
GOV Settings
The GOV structure describes the composition of the MPEG-4 video stream. Setting the GOV-length to a high
value saves considerably on bandwidth. The Cyclic refresh parameter gives a smoother bit rate and can be
useful if bandwidth is limited.
Note: Cyclic refresh should not be enabled if Event handling is enabled and the file format is set to MPEG-4 in Upload images/video (see
Setup > Event configuration > Event settings).
Bit Rate Control
Limiting the maximum bit rate is a good way of controlling the bandwidth used by the MPEG-4 video stream.
Leaving the maximum bit rate as unlimited will provide consistently good image quality, but at the expense of
increased bandwidth usage whenever there is more activity in the image. Limiting the bit rate to a defined value
will prevent excessive bandwidth usage, but images will be lost when the limit is exceeded.
Note that a maximum bit rate can be used for both variable and constant bit rates.
The bit rate type can be set as Variable Bit Rate (VBR) or Constant Bit Rate (CBR). VBR will adjust the bit rate
according to the images' complexity, thus using a lot of bandwidth for a lot of activity in the image and less for
lower activity in the monitored area.
CBR allows you to set a fixed Target bit rate that will consume a predictable amount of bandwidth, and which
will not change whatever happens in the image.
As the bit rate would usually need to increase for increased image activity, but in this case cannot, the frame
rate and image quality will be affected negatively. To go some of the way towards compensating for this, it is
possible to prioritize either the frame rate or the image quality whenever the bit rate would normally need to be
increased. Not setting a priority means the frame rate and image quality will be affected approximately equally.
AXIS 211W - Audio Settings
Audio Settings
The AXIS 211W can transmit audio to other clients using a connected external microphone or the internal
microphone and can play audio received from other clients via connected speakers. This section describes how
to configure the basic audio settings for the AXIS 211W, e.g. set the communication mode and adjust the sound
levels in the microphone and speakers connected to the camera.
Note: The speakers connected to the audio output must have a built-in amplifier, e.g. Client PC
PC speakers.
Enable Audio
Check this box to enable audio in the AXIS 211W.
TCP/IP Network
Audio Channels - Audio mode
Full duplex mode is simultaneous two-way audio where you can
transmit and receive audio at the same time.
Example of a network
Half duplex mode transmits and receives audio in both directions,
using AXIS 211W cameras to transmit
but only in one direction at a time. This means that you must select
audio and video across the network.
when to receive or transmit audio with the push-to-talk button. To
speak, press and hold the button (check that the microphone is not muted). When finished speaking, release the
button and you will receive audio from the other end of the connection.
Note that the push-to-talk button is configured from AMC. It is also possible to configure the push-to-talk
button so that it toggles between speaking and listening modes.
When selecting Simplex - Network Camera speaker only mode, the speaker connected to the camera will play
audio, but no audio will be transmitted from the camera to other web clients. This could be used to, e.g. provide
spoken instructions to a person seen in the camera. This mode requires you to use the push-to-talk button.
Simplex - Network Camera microphone only mode transmits audio only from the AXIS 211W to web clients.
It will not receive audio from any other web clients. This can be used in remote monitoring, web attractions etc.,
to provide live audio, as well as video, of a monitored situation.
When using half duplex, the Send the sound from the active client to all other clients option transmits the
audio signal from the client that is talking to all the other clients.
Audio Input
Audio from a connected microphone or a line source can be connected to the Audio in connector of the AXIS
211W. The audio source must be set to Microphone or Line depending on the connected device.
Note: To prevent unauthorized listening, the internal microphone can be disabled by inserting a plug in the Audio in connector.
The Enable microphone power option provides DC power for an external microphone. If using a small electret
microphone such as a clip-on mic or a PC microphone, this option needs to be enabled.
Note: When using a high impedance dynamic microphone Enable microphone power should not be checked. To use a professional microphone requiring 48V phantom power, you need an external power supply and must use a balanced-unbalanced converter (audio transformer) in between.
Set Input sensitivity to High or Low depending on the sound level in the monitored area. For example, if the
AXIS 211W is installed in a noisy environment set the sensitivity to Low. When using an external microphone
set the Input sensitivity to High if you are using an ordinary, unamplified microphone. Set the sensitivity to
Low if the connected microphone has a built-in line amplifier.
Enable microphone power with electret microphones that have no battery. Do not use this setting with a
dynamic or battery powered microphone.
Select the desired audio Encoding format G711, G726 or AAC.
AXIS 211W - Audio Settings
Depending on the selected encoding, set the desired Bit rate (audio quality). The settings affects the available
bandwidth and the audio quality, i.e. a high bit rate setting requires more bandwidth.
The AXIS 211W can be set to trigger an event if the incoming sound level rises above, falls below or passes the
set value. The Alarm level is set between 0-100%.
Audio Output
If the sound from the speaker is too low or high, adjust the output gain for the active speaker attached to the
AXIS 211W. When satisfied with the settings, click Save, or click Reset to revert to the previously saved
Advanced Audio
Advanced audio settings can improve audio quality by speech filtering, echo cancellation or setting the noise
canceller threshold value or attenuation.
When enabled the speech filter reduces noise by filtering out all the frequencies below 100HZ and above 3500
Hz. This improves the sound quality if a person is close to the microphone when talking and will reduce
background noises.
Enable echo cancellation to reduce acoustic echoing that can be caused by audio coming from a speaker being
captured by a microphone.
Noise canceling is a way of reducing the background noise if the microphone, for example, is set up in a noisy
environment and you are only interested in hearing a person who is talking close to the microphone. The noise
canceller attenuation produces maximum noise reduction when set to 18dB of attenuation. Optimize the sound
quality by listening to the sound and adjusting the attenuation level as required.

Up to 10 event types can be configured in the camera, and up to 3 of these can be configured to upload images.
Pre-trigger and Post-trigger buffers
This function is very useful when checking to see what happened immediately before and/or after a trigger, e.g.
up to 30 seconds before and/or after a door was opened. Check the Upload images checkbox under Event Types
> Add Triggered... > Triggered by... to expand the web page with the available options. All uploaded images
are JPEG images.
Include pre-trigger buffer - images stored internally in the camera from the time immediately preceding the
trigger. Check the box to enable the pre-trigger buffer, enter the desired length of time and specify the required
image frequency.
Include post-trigger buffer - contains images from the time immediately after the trigger. Configure as for
•Pre-trigger and Post-trigger buffers will be lost if the connection to the event server fails.
•The maximum length of the pre-/post-buffer depends on the video image size and selected frame rate.
•If the pre- or post-buffer is too large for the camera’s internal memory, the frame rate will be reduced and individual images may be
missing. If this occurs, an entry will be created in the unit's log file.
Continue image upload (unbuffered) - enables the upload of video images for a fixed length of time. Specify
the length of time for the uploaded recording, in seconds, minutes or hours, or for as long as the trigger is
active. Finally, set the desired image frequency to the maximum (the maximum available) or to a specified frame
rate. The frame rate will be the best possible, but might not be as high as specified, especially if uploading via a
slow connection.

AXIS 211W - System Options
System Options
User access control is enabled by default, when the administrator sets the root password on first access. An
administrator can set up other users, by giving these user names and passwords. It is also possible to allow
anonymous viewer login, which means that anybody may access the Live View page, as described below:
Users - the user list displays the authorized users and user groups (levels):
Provides the lowest level of access, which only allows access to the Live View page.
An operator can view the Live View page, create and modify event types and adjust certain
other settings. Operators have no access to the System Options.
An administrator has unrestricted access to all the setup tools and can determine the
registration of all other users.
User Settings - check the relevant check box to enable:
• Anonymous viewer login - allows any viewer direct access to the Live View page.
• Maximum number of simultaneous viewers - enter a value here to restrict the number of unicast viewers
accessing the unit. This is useful if you need to save on bandwidth. (Note that all multicast viewers count as
1 viewer.)
IP Address Filtering
Checking the Enable IP address filtering box enables the IP address filtering function, whereby the IP addresses
in the list of filtered addresses will be allowed or denied access to the AXIS 211W.
Up to 256 IP address entries may be specified (a single entry can contain multiple IP addresses). All other IP
addresses not in this list will be allowed or denied access accordingly, i.e. if the addresses in the list are allowed,
then all others are denied access, and vice versa. Click the Add button to add new filtered addresses. See also the
online help for more information.
Referrals - To prevent unauthorized clients from including the video stream from the cameras into external
Web pages, check the Referrals checkbox and enter the IP address or Host name of the computer that hosts the
Web pages with the included video stream. Several IP addresses/host names can be defined and are separated by
semicolons (;). This option is only applicable to Motion JPEG video streams.
Notes: If the referrals feature is enabled and you wish to also allow normal access to the Live View page, the product's own IP address or host
name must be added to the list of allowed referrers.
Restricting referrers has no effect on an MPEG-4 video stream. To restrict an MPEG-4 stream, IP address filtering must be enabled.
Restricting referrers is of greatest value when not using IP address filtering. If IP address filtering is used, then the allowed referrers
are automatically restricted to those allowed IP addresses.
The AXIS 211W supports encrypted browsing using HTTPS.
A self-signed certificate can be used until a Certificate Authority-issued certificate has been obtained. Click the
Create self-signed Certificate button to install a self-signed certificate. Although self-signed certificates are free
and offer some protection, true security will only be implemented after the installation of a signed certificate
issued by a certificate authority.
A signed certificate can be obtained from an issuing Certificate Authority by clicking the Create Certificate
Request button. When the signed certificate is returned, click the Install signed certificate button to import the
certificate. The properties of any certificate request currently resident in the camera or installed can also be
viewed by clicking the Properties... button. The HTTPS Connection Policy must also be set in the drop-down
lists to enable HTTPS in the camera. For more information, please refer to the online help.
AXIS 211W - System Options
802.1X - Network Admission Control
The settings here enable AXIS 211W to access a wired network protected by 802.1X/EAPOL(Extensible
Authentication Protocol Over LAN). IEEE 802.1X is an IEEE standard for port-based Network Admission Control.
It provides authentication to devices attached to a network port, establishing a point-to-point connection, or if
authentication fails, preventing access on that port. 802.1X is based on EAP (Extensible Authentication
In a 802.1X enabled network switch, clients equipped with the correct software can be authenticated and
allowed or denied network access at the Ethernet level.
Clients and servers in an 802.1X network may need to authenticate each other by some means. In the Axis
implementation this is done with the help of digital certificates provided by a Certification Authority. These are
then validated by a third-party entity, such as a RADIUS server, examples of which are FreeRADIUS and
Microsoft Internet Authentication Service.
To perform the authentication, the RADIUS server uses various EAP methods/protocols, of which there are
many. The one used in the Axis implementation is EAP-TLS (EAP-Transport Layer Security).
The AXIS network video device presents its certificate to the network switch, which in turn forwards this to the
RADIUS server. The RADIUS server validates or rejects the certificate and responds to the switch, and sends its
own certificate to the client for validation. The switch then allows or denies network access accordingly, on a
preconfigured port.
The authentication process
1. A CA server provides the required signed certificates.
2. The Axis video device requests access to the protected network at the network switch. The switch
forwards the video device’s CA certificate to the RADIUS server, which then replies to the switch.
3. The switch forwards the RADIUS server’s CA certificate to the video device, which also replies to the
4. The switch keeps track of all responses to the validation requests. If all certificates are validated, the
Axis video device is allowed access to the protected network via a preconfigured port.
RADIUS (Remote Authentication Dial In User Service) - AAA (Authentication, Authorization and Accounting)
protocol for applications such as network access or IP mobility. It is intended to work in both local and roaming
CA servers - In cryptography, a Certification Authority (CA) is an entity that provides signed digital certificates
for use by other parties, thus acting a trusted third party. There are many commercial CA’s that charge for their
services. Institutions and governments may have their own CA, and there are free CA’s available.
Date & Time
Current Server Time - displays the current date and time (24h clock). The time can be displayed in 12h clock
format in the Overlay (see below).
New Server Time - Select your time zone from the drop-down list. If you want the server clock to automatically
adjust for daylight savings time, select the Automatically adjust for daylight saving time changes.
From the Time Mode section, select the preferred method to use for setting the time:
• Synchronize with computer time - sets the time from the clock on your computer.
• Synchronize with NTP Server - the camera will obtain the time from an NTP server every 60 minutes.
The NTP Server can be set under Network > TCP/IP > Advanced or click on the No server specified
link, see NTP Configuration, on page 30.
• Set manually - this option allows you to manually set the time and date.
Date & Time Format Used in Images - specify the formats for the date and time (12h or 24h) displayed in the
video streams.

Network - Basic TCP/IP Settings
IP Address Configuration
The AXIS 211W supports both IP version 4 and IP version 6 for both Ethernet and wireless connections. Both
versions may be enabled simultaneously, and at least one version must always be enabled.
When using IPv4, the IP address for the AXIS 211W can be set automatically via DHCP, or a static IP address
can be set manually. If IPv6 is enabled, the AXIS 211W will receive an IP address according to the configuration
in the network router.
Status shows if the IP address configuration is Active or Inactive. For example, if the AXIS 211W is connected
to the network through an Ethernet cable the IPv4 Address Configuration - Wireless status shows as inactive.
There are also options for setting up notification of changes in the IP address, and for using the AXIS Internet
Dynamic DNS Service. For more information on setting the IP address, please see the online help.
•DHCP is a protocol for automatic IP address assignment on a network. IP address assignment via DHCP may lead to the
situation where the IP address changes and you lose contact with the camera. Configure the options for notification of IP
address change (under Services) to receive notification from the camera when the IP address changes.
•Alternatively, if your DHCP server can update a DNS server, you can access the AXIS 211W by host name which is always
the same, regardless of the IP address.
Enable ARP/Ping setting of IP address - The IP address can be set using the ARP/Ping method, which associates
the unit's MAC address with an IP address. Check this box to enable the service. Leave disabled to prevent
unintentional resetting of the IP address.
•The ARP/Ping service is automatically disabled 2 minutes after the unit is started, or as soon as an IP address is set.
•Pinging the unit will still be possible when this service is disabled.
Options for notification of IP address change - If the IP address for the camera changes, e.g. automatically by
DHCP, you can choose to be notified of the change. Click Settings... and enter the required information.
AXIS Internet Dynamic DNS Service - Use the AXIS Internet Dynamic DNS service to assign a host name for
easy access to your AXIS 211W Network Camera (requires Internet access).
Click Settings... to register the AXIS 211W with the Axis Internet Dynamic DNS service, or to modify the
existing settings (requires access to the Internet). The domain name currently registered at the Axis Internet
Dynamic DNS service for your product can at any time be removed.
For more information, please refer to the online help.
Network - Advanced TCP/IP Settings

DNS (Domain Name Service) provides the translation of host names to IP addresses on your network.
Obtain DNS server address via DHCP - automatically use the DNS server settings provided by the DHCP server.
Click the View button to see the current settings.
AXIS 211W - System Options
Use the following DNS server address - enter the desired DNS server by specifying the following:
Domain name - enter the domain(s) to search for the host name used by the AXIS 211W. Multiple domains can
be separated by semicolons (;). The host name is always the first part of a Fully Qualified Domain Name, e.g.
myserver is the host name in the Fully Qualified Domain Name where is the Domain name.
DNS servers - enter the IP addresses of the primary and secondary DNS servers.
NTP Configuration
Obtain NTP server address via DHCP - check this radio button to automatically look up and use the NTP server
settings as provided by DHCP. Click the View button to see the current settings.
Use the following NTP server address - to make manual settings, check this radio button and enter the host
name or IP address of the NTP server.
Note: If using a host name for the NTP server, a DNS server must be configured under TCP/IP settings. See Network > TCP/IP below.
Host Name Configuration
The AXIS 211W can be accessed using a host name, instead of an IP address. The host name is usually the same
as the assigned DNS Name. For more information, see the online help.
Link-Local IPv4 Address
This is enabled by default and assigns the AXIS 211W an additional IP address for use with UPnP™. The AXIS
211W can have both a Link-Local IP and a static/DHCP-supplied IP address at the same time - these will not
affect each other.
The default HTTP port number (80) can be changed to any port within the range 1024-65535. This is useful for,
e.g. simple security port mapping.
If applicable, enter the HTTPS port the AXIS 211W will use. The default setting (443) can be changed to any port
within the range 1024-65535. HTTPS is used to provide encrypted web browsing.
NAT traversal (port mapping) for IPv4
A broadband router allows devices on a private network (LAN) to share a single connection to the Internet. This
is done by forwarding network traffic from the private network to the “outside”, i.e. the Internet. Security on the
private network (LAN) is increased since most broadband routers are pre-configured to stop any attempts to
access the private network (LAN) from the public network/Internet.
Use NAT traversal when your AXIS 211W is located on an intranet (LAN) and you wish to make it available
from the other (WAN) side of a NAT router. With NAT traversal properly configured, all HTTP traffic to an
external HTTP port in the NAT router will be forwarded to the camera.
LAN (intranet)
WAN (Internet)
For NAT traversal to work, this must also be supported by the broadband router.
The broadband router has many different names: “NAT router”, “Network router“, Internet Gateway”, “Broadband
sharing device” or “Home firewall” but the essential purpose of the device is the same.
AXIS 211W - System Options
Enable/Disable - When enabled, the AXIS 211W will attempt to configure port mapping in a NAT router on
your network, using UPnP™. Note that UPnP™ must be enabled in the camera (see System Options > Network >
Use manually selected NAT router - Select this option to manually select a NAT router and enter the IP address
for the router in the field provided.
If a router is not manually specified, the AXIS 211W will automatically search for NAT routers on your network.
If more than one router is found, the default router will be selected.
Alternative HTTP port - Select this option to manually define an external HTTP port. Enter the port number in
the field provided. If no port is entered here a port number will automatically be selected when NAT traversal is
•An alternative HTTP port can be used/be active even if NAT traversal is disabled. This is useful if, e.g. your NAT router does
not support UPnP and you need to manually configure port forwarding in the NAT router.
•If a manually selected port is already in use, another will automatically be selected.
•When the port is selected automatically it will be displayed in this field. This can be changed by entering a new port
number and clicking Save.
The FTP server running in the AXIS 211W enables the upload of, e.g. new firmware, user applications, etc.
Check the box to enable the service.
The RTSP protocol allows a connecting client to start an MPEG-4 stream. Check the box to enable the service
and enter the RTSP port number to use. The default setting (554) can be changed to any port within the range
Network Traffic
Connection Type - The default setting is Auto-negotiate, which means that the correct speed is automatically
selected. If necessary, you can set the connection speed by selecting it from the drop-down list.
Wireless settings in the AXIS 211W must be the same as the access point or ad-hoc device. When changing the
settings they should always be made first in the camera and then in the wireless access point. This ensures that
the camera is always accessible when making changes.
Status of Wireless Networks
This list is the result of a network scan. Access points with a disabled SSID Broadcast will not appear unless the
camera is linked to it. The network the AXIS 211W is currently linked to is shown in blue. A network using
unsupported security is shown in grey. The following information is provided:
• SSID - The name of a wireless network (or ad-hoc device). If the same name occurs several times this means that
several access points for that network were found. The camera cannot be configured to only associate with one
particular access point.
• Mode - Shows if the network type is Master (access point or router) or Ad-Hoc (another client).
• Security - Shows which type of security the network uses. See below for the security types supported by the
• Channel - Shows the wireless channel currently in use.
• Signal strength - Shows the signal strength.
• Bit rate - Shows the bit rate in Mbit/s. This can only be shown for the access point currently in use. Note that the
bit rate shown is the current rate, and that this value may vary over time.
AXIS 211W - System Options
Wireless Settings
These settings control how the camera interacts with the wireless network. Apart from identifying the wireless
network, it is also possible to enable wireless encryption.
SSID - This is the name of the wireless network the camera is configured for. The field accepts up to 32
alphanumeric characters. The name must be exactly the same as that used in the wireless access point or the
connection will not be established.
Leaving this field blank means the camera will attempt to access the nearest open network.
Note: SSID is sometimes written as ESSID.
Network type - Setting this to Master means the camera will attempt to access the nearest open access point.
The Ad-hoc option allows the camera to connect to other wireless devices (clients).
Note: WEP is the only available encryption method for Ad-hoc setting(see below).
Security - The AXIS 211W has three security options:
• WPA-/WPA2-Enterprise
WPA-/WPA2-Enterprise is more secure than WPA-/WPA2-PSK, which in turn is more secure than WEP. For
detailed instructions for setting up Wireless security in your AXIS 211W refer to the Installation Guide.
WPA-/WPA2-PSK (Wi-Fi Protected Access - Pre-Shared Key)
The AXIS 211W uses a pre-shared key (PSK) to initiate WPA security. The pre-shared key is entered on the
access point and on each device on the wireless network. The key can be entered either as Manual hex, as 64
hexadecimal (0-9, A-F) characters, or as a Passphrase, using 8 to 63 ASCII characters. The access point keeps out
unauthorized users by requiring the key to communicate.
WPA-/WPA2-Enterprise (Wi-Fi Protected Access - Enterprise)
WPA-/WPA2-Enterprise is a security method that provides strong data protection for multiple users and large
networks. It uses the 802.1X authentication framework with TKIP or AES encryption. Network users trying to
gain access are verified through an authentication server.
Certificates-The client and server authenticate each other using digital certificates provided by a Certificate
Authority. To gain access to the protected network, the AXIS 211W presents its certificate to the network switch.
If the certificate is approved, the switch allows access. You may need to contact your network administrator for
information on certificates, user IDs and passwords. For more information about certificates
For more information on certificates see page 28 and refer to the online help.
WEP (Wired Equivalent Protection)
The original security standard used in wireless networks that provides a minimal level of security that can deter
minor trespasses.
Note: Configuring the AXIS 211W using an unsecured wireless connection is not recommended, since passphrases and keys saved will be
sent in plain text. The fastest, most secure method to configure AXIS 211W is using a wired connection, since it disables the wireless
connection and ensures greater secrecy while entering settings.
SOCKS is a networking proxy protocol. The AXIS 211W can be configured to use a SOCKS server to reach
networks on the other side of a firewall/proxy server. This functionality is useful if the AXIS 211W is located on
a local network behind a firewall, but notifications, uploads, alarms, etc., need to be sent to a destination outside
the local network (e.g. to the Internet).
AXIS 211W - System Options
QoS (Quality of Service)
Quality of Service (QoS) provides the means to guarantee a certain level of a specified resource to selected traffic
on a network. Quality can be defined as, e.g. a maintained level of bandwidth, low latency, no packet losses, etc.
The main benefits of a QoS-aware network can be summarized as:
•The ability to prioritize traffic and thus allow critical flows to be served before flows with lesser priority.
•Greater reliability in the network, thanks to the control of the amount of bandwidth an application may use,
and thus control over bandwidth races between applications.
The QoS in Axis network video products marks the data packets for various types of network traffic originating
from the product. This makes it possible for network routers and switches to, e.g. reserve a fixed amount of
bandwidth for these types of traffic. The types of traffic marked by the camera are video, audio, event/alarm and
management network traffic.
QoS DSCP Settings
For each type of network traffic supported by your Axis network video product, enter a DSCP (Differentiated
Services Codepoint) value. This value is used to mark the traffic’s IP header. When the marked traffic reaches a
network router or switch, the DSCP value in the IP header tells the router or switch which type of treatment to
apply to this type of traffic, for example, how much bandwidth to reserve for it.
Note that DSCP values can be entered in decimal or hexadecimal format, but saved values are always shown in
decimal. For more information on Quality of Service, please see the Axis support web at
SMTP (email)
Enter the host names or addresses for your primary and secondary mail servers in the fields provided, to enable
the sending of notifications and image email messages from the camera to predefined addresses via SMTP.
If your mail server requires authentication, check the box for Use authentication to log in to this server and
enter the necessary information.
The Simple Network Management Protocol (SNMP) allows remote management of network devices. Depending
on the level of security required, select the version of SNMP to use. The three levels of security are:
• SNMP V1 - includes no security.
• SNMP V2c - uses very simple security. The community name can be specified as a password for read or
read/write access to all supported SNMP objects. The community is the group of network devices using
• SNMP V3 - provides encryption and secure passwords. HTTPS must be enabled.
The camera includes support for UPnP™, which is enabled by default. If also enabled on your computer, the
camera will automatically be detected and a new icon will be added to “My Network Places.”
Note: Check your operating system’s documentation for enabling UPnP™
These settings are the port range, IP address, port number (video and audio), and Time-To-Live value to use for
the video stream(s) in multicast MPEG-4 format. Only certain IP addresses and port numbers should be used for
multicast streams. For more information, please see the online help.
The AXIS 211W includes support for Bonjour. When enabled, the camera is automatically detected by operating
systems and clients that support this.

AXIS 211W - Technical Specifications
General performance considerations
When setting up your system, it is important to consider how various settings and situations will affect
performance. Some factors affect the amount of bandwidth (the bit rate) required, others can affect the frame
rate, and some will affect both. If the load on the CPU reaches its maximum, this will also affect the frame rate.
The following factors are among the most important to consider:
• High image resolutions and/or lower compression levels result in larger images. Bandwidth affected.
• Access by large numbers of Motion JPEG and/or unicast MPEG-4 clients. Bandwidth affected.
• Simultaneous viewing of different streams (resolution, compression, rotation, etc.) by different clients.
Frame rate and bandwidth affected.
• Accessing both Motion JPEG and MPEG-4 video streams simultaneously. Frame rate and bandwidth
• Heavy usage of event settings affects the camera’s CPU load. Frame rate affected.
• Enabled motion detection. Frame rate and bandwidth affected.
• Heavy network utilization due to poor infrastructure. Bandwidth affected
• Viewing on poorly performing client PC’s lowers perceived performance. Frame rate affected.
• Access to WLAN. Frame rate affected.
Optimizing your system
To see the bandwidth and frame rate currently required by the video stream, the AXIS 211W provides a tool that
can be used to display these values directly in the video image.
To do this, special format strings are added as part of a text overlay.
Simply add #r (average frame rate in fps) and/or #b (average bandwidth
in kbps) to the overlay.
For detailed instructions, please see the online help for Video & Image >
Overlay Settings, and the help for File Naming & Date/Time Formats.
AXIS 211W - Troubleshooting
Checking the Firmware
Firmware is software that determines the functionality of the AXIS 211W. One of your first actions when
troubleshooting a problem should be to check the currently installed firmware version. The latest version may
contain a correction that fixes your particular problem. The current firmware version in your camera can be
seen on the page Setup > Basic Configuration.
Upgrading the Firmware
When you upgrade the firmware with a file from the Axis Web site, your Axis camera will receive the latest
available functionality. Always read the upgrade instructions and release notes available with each new release,
before updating the firmware.
Note: Preconfigured and customized settings will be saved when the firmware is upgraded (providing the features are available in the new
firmware) although this is not guaranteed by Axis Communications.
1. Save the firmware file to your computer. The latest version of the firmware is available free of charge
from the Axis Web site at
2. Go to Setup > System Options > Maintenance in the camera’s Web pages.
3. In the Upgrade Server section, browse to the desired firmware file on your computer. Click Upgrade.
•After starting the upgrade process, always wait at least 5-10 minutes before restarting the camera, even if you suspect
the upgrade has failed.
•Your dealer reserves the right to charge for any repair attributable to faulty upgrading by the user.
•Always read the upgrade instructions available with each new release, before updating the firmware.
Emergency Recovery Procedure
If power to the camera is lost during the upgrade, the process will fail and the unit will become unresponsive. A
flashing red Status LED indicates a failed upgrade. To recover the unit, follow the steps below. This procedure is
only possible to perform via a wired connection. Connect the AXIS 211W to the network with a standard
network cable. The serial number is found on the label attached to the bottom of the camera.

AXIS 211W - Glossary of Terms
Glossary of Terms
CCD (Charged Coupled Device) - This light-sensitive image device used
in many digital cameras is a large integrated circuit that contains
hundreds of thousands of photo-sites (pixels) that convert light energy
into electronic signals. Its size is measured diagonally and can be 1/4",
1/3", 1/2" or 2/3".
802.1X - An IEEE standard for port-based Network Admission Control.
It provides authentication to devices attached to a network port (wired
or wireless), establishing a point-to-point connection, or, if
authentication fails, preventing access on that port. 802.1X is based on
EAP (Extensible Authentication Protocol).
CGI (Common Gateway Interface) - A specification for communication
between a web server and other (CGI) programs. For example, a HTML
page that contains a form might use a CGI program to process the form
data once it is submitted.
ActiveX - A standard that enables software components to interact with
one another in a networked environment, regardless of the language(s)
used to create them. Web browsers may come into contact with ActiveX
controls, ActiveX documents, and ActiveX scripts. ActiveX controls are
often downloaded and installed automatically as required.
CIF (Common Intermediate Format) - CIF refers to the analog video
resolutions 352x288 pixels (PAL) and 352x240 pixels (NTSC). See also
Client/Server - Client/server describes the relationship between two
computer programs in which one program, the client, makes a service
request from another program, the server, which fulfils the request.
Typically, multiple client programs share the services of a common
server program. A web browser is a client program that requests services
(the sending of web pages or files) from a web server.
AF (Autofocus) - A system by which the camera lens automatically
focuses on a selected part of the subject.
Angle - The field of view, relative to a standard lens in a 35mm still
camera, expressed in degrees, e.g. 30°. For practical purposes, this is the
area that a lens can cover, where the angle of view is determined by the
focal length of the lens. A wide-angle lens has a short focal length and
covers a wider angle of view than standard or telephoto lenses, which
have longer focal lengths.
CMOS (Complementary Metal Oxide Semiconductor) - A CMOS is a
widely used type of semiconductor that uses both negative and positive
circuits. Since only one of the circuit types is on at any given time,
CMOS chips require less power than chips using just one type of
transistor. CMOS image sensors also allow processing circuits to be
included on the same chip, an advantage not possible with CCD sensors,
which are also much more expensive to produce.
ARP (Address Resolution Protocol) - This protocol is used to associate
an IP address to a hardware MAC address. A request is broadcast on the
local network to discover the MAC address for an IP address.
ARTPEC (Axis Real Time Picture Encoder) - This chip is used for image
Codec - In communications engineering, a codec is usually a
coder/decoder. Codecs are used in integrated circuits or chips that
convert, e.g. analog video and audio signals into a digital format for
transmission. The codec also converts received digital signals back into
analog format. A codec uses analog-to-digital conversion and
digital-to-analog conversion in the same chip.
ASIC (Application Specific Integrated Circuit) - A circuit designed for
a specific application, as opposed to a general purpose circuit, such as a
Aspect ratio - A ratio of width to height in images. A common aspect
ratio used for television screens and computer monitors is 4:3.
High-definition television (HDTV) uses an aspect ratio of 16:9.
Codec can also mean compression/decompression, in which case it is
generally taken to mean an algorithm or computer program for reducing
the size of large files and programs.
Autoiris (or DC-Iris) - This special type of iris is electrically controlled
by the camera, to automatically regulate the amount of light allowed to
Compression - See Image Compression.
AVI (Audio Video Interleave) - A video format that supports
simultaneous playback of audio and video.
Contrast - Defines the degree of difference between the lightest and
darkest parts of an image or video stream.
Bitmap - A bitmap is a data file representing a rectangular grid of
pixels. It defines a display space and color for each pixel (or "bit") in the
display space. This type of image is known as a "raster graphic." GIF's
and JPEG's are examples of image file types that contain bitmaps.
DC-Iris - This special type of iris is electrically controlled by the
camera, to automatically regulate the amount of light allowed to enter.
DHCP (Dynamic Host Configuration Protocol) - DHCP is a protocol
that lets network administrators automate and centrally manage the
assignment of Internet Protocol (IP) addresses to network devices in a
Because a bitmap uses this fixed raster method, it cannot easily be
rescaled without losing definition. Conversely, a vector graphic image
uses geometrical shapes to represent the image, and can thus be quickly
DHCP uses the concept of a "lease" or amount of time that a given IP
address will be valid for a computer. The lease time can vary, depending
on how long a user is likely to require the network connection at a
particular location.
Bit rate - The bit rate (in kbit/s or Mbit/s) is often referred to as speed,
but actually defines the number of bits/time unit and not distance/time
DHCP also supports static addresses for, e.g. computers running web
servers, which need a permanent IP address.
Bluetooth - Bluetooth is an open standard for wireless transmission of
voice and
data between
(PCs, handheld computers,
telephones and printers).
DNS (Domain Name System) - DNS is used to locate and translate
Internet domain names into IP (Internet Protocol) addresses. A domain
name is a meaningful and easy-to-remember name for an Internet
address. For example the domain name is much
easier to remember than The translation tables for domain
names are contained in Domain name servers.
Bonjour - Also known as zero-configuration networking, Bonjour
enables devices to automatically discover each other on a network,
without having to enter IP addresses or configure DNS servers. Bonjour
is a trademark of Apple Computer, Inc.
Domain Server - Domains can also be used by organizations who wish
to centralize the management of their (Windows) computers. Each user
within a domain has an account that usually allows them to log in to
and use any computer in the domain, although restrictions may also
apply. The domain server is the server that authenticates the users on
the network.
Broadband - In network engineering terms, this describes transmission
methods where two or more signals share the same carrier. In more
popular terminology, broadband is taken to mean high-speed data
Certificate authority (CA) - Is an entity that issures digital certificates
which contains public key and private key pairs. The CA verifies an
applicant’s credentials, so that users can trust the information in the
Duplex - See Full-duplex.
AXIS 211W - Glossary of Terms
Ethernet - Ethernet is the most widely installed local area network
technology. An Ethernet LAN typically uses special grades of twisted
pair wires. The most commonly installed Ethernet systems are 10BASE-T
and 100BASE-T10, which provide transmission speeds up to 10 Mbps
and 100 Mbps respectively.
HTML (Hypertext Markup Language) - HTML is the set of "markup"
symbols or codes inserted in a file intended for display in web browser.
The markup tells the browser how to display the page's words and
images for the user.
HTTP (Hypertext Transfer Protocol) - HTTP is the set of rules for
exchanging files (text, graphic images, sound, video, and other
multimedia files) on the web. The HTTP protocol runs on top of the
TCP/IP suite of protocols.
ETRAX (Ethernet Token Ring AXIS) - Axis' own microprocessor.
Factory default settings - These are the settings that originally applied
for a device when it was first delivered from the factory. If it should
become necessary to reset a device to its factory default settings, this
will, for many devices, completely reset any settings that were changed
by the user.
Hub - A (network) hub is used to connect multiple devices to the
network. The hub transmits all data to all devices connected to it,
whereas a switch will only transmit the data to the device it is
specifically intended for.
Firewall - A firewall works as a barrier between networks, e.g. between
a Local Area Network and the Internet. The firewall ensures that only
authorized users are allowed to access the one network from the other. A
firewall can be software running on a computer, or it can be a
standalone hardware device.
IEEE 802.11 - A family of standards for wireless LANs. The 802.11
standard supports 1 or 2 Mbit/s transmission on the 2.4 GHz band. IEEE
802.11b specifies an 11 Mbit/s data rate on the 2.4 GHz band, while
802.11g allows up to 54 Mbit/s on the 2.4 GHz band.
Focal length - Measured in millimeters, the focal length of a camera
lens determines the width of the horizontal field of view, which in turn
is measured in degrees.
Image compression - Image compression minimizes the file size (in
bytes) of an image. Two of the most common compressed image formats
are JPEG and GIF.
FTP (File Transfer Protocol) - An application protocol that uses the
TCP/IP protocols. It is used to exchange files between computers/devices
on networks.
Interlacing - Interlaced video is video captured at 50 pictures (known as
fields) per second, of which every 2 consecutive fields (at half height)
are then combined into 1 frame. Interlacing was developed many years
ago for the analog TV world and is still used widely today. It provides
good results when viewing motion in standard TV pictures, although
there is always some degree of distortion in the image.
Frame - A frame is a complete video image. In the 2:1 interlaced
scanning format of the RS-170 and CCIR formats, a frame is made up of
two separate fields of 262.5 or 312.5 lines interlaced at 60 or 50 Hz to
form a complete frame, which appears at 30 or 25 Hz. In video cameras
with a progressive scan, each frame is scanned line-by-line and not
interlaced; most are also displayed at 30 and 25 Hz.
To view interlaced video on, e.g. a computer monitor, the video must
first be de-interlaced, to produce progressive video, which consists of
complete images, one after the other, at 25 frames per second. See also
Progressive scan.
Frame rate - The frame rate used to describe the frequency at which a
video stream is updated is measured in frames per second (fps). A higher
frame rate is advantageous when there is movement in the video stream,
as it maintains image quality throughout.
IP (Internet Protocol) - The Internet Protocol is a method transmitting
data over a network. Data to be sent is divided into individual and
completely independent "packets." Each computer (or host) on the
Internet has at least one address that uniquely identifies it from all
others, and each data packet contains both the sender's address and the
receiver's address.
Full-duplex - Transmission of data in two directions simultaneously. In
an audio system this would describe, e.g. a telephone systems.
Half-duplex also provides bi-directional communication, but only in one
direction at a time, as in a walkie-talkie system. See also Simplex.
The Internet Protocol ensures that the data packets all arrive at the
intended address. As IP is a connectionless protocol, which means that
there is no established connection between the communication
end-points, packets can be sent via different routes and do not need to
arrive at the destination in the correct order.
Gain - Gain is the amplification factor and the extent to which an
analog amplifier boosts the strength of a signal. Amplification factors
are usually expressed in terms of power. The decibel (dB) is the most
common way of quantifying the gain of an amplifier.
Gateway - A gateway is a point in a network that acts as an entry point
to another network. In a corporate network for example, a computer
server acting as a gateway often also acts as a proxy server and a
firewall server. A gateway is often associated with both a router, which
knows where to direct a given packet of data that arrives at the gateway,
and a switch, which furnishes the actual path in and out of the gateway
for a given packet.
Once the data packets have arrived at the correct destination, another
protocol - Transmission Control Protocol (TCP) - puts them in the right
order. See also TCP.
GIF (Graphics Interchange Format) - GIF is one of the most common
file formats used for images in web pages. There are two versions of the
format, 87a and 89a. Version 89a supports animations, i.e. a short
images Quick
within aUser’s
single GIF
file. A GIF89a can also be
specified for interlaced presentation.
To avoid conflicts, each IP address on any given network must be
unique. An IP address can be assigned as fixed, so that it does not
change, or it can be assigned dynamically (and automatically) by DHCP.
IP Address - An IP address is simply an address on an IP network used
by a computer/device connected to that network. IP addresses allow all
the connected computers/devices to find each other and to pass data
back and forth.
An IP address consists of four groups (or quads) of decimal digits
separated by periods, e.g. Different parts of the address
represent different things. Some part will represent the network number
or address, and some other part will represent the local machine address.
GOV (Group Of VOPs) - A group of VOP's is the basic unit of an
MPEG-4 video stream. The GOV contains different types and numbers of
VOP's (I-VOP's, P-VOP's, etc) as determined by the GOV length and GOV
structure. See also VOP.
See also IP (Internet Protocol).
I-VOP - See VOP.
GOV length - The GOV length determines the number of images (VOP's)
in the GOV structure. See also GOV and VOP.
IPv6 (Internet Protocol version 6) - A set of specifications designed as
improvements to the current IP Version 4. Network hosts and
intermediate nodes with either IPv4 or IPv6 can handle packets for
either level of the Internet Protocol.
GOV structure - The GOV structure describes the composition of an
MPEG-4 video stream, as regards the type of images (I-VOP's or
P-VOP's) included in the stream, and their internal order. See also GOV
and VOP.
JPEG (Joint Photographic Experts Group) - Together with the GIF file
format, JPEG is an image file type commonly used on the web. A JPEG
image is a bitmap, and usually has the file suffix '.jpg' or ".jpeg." When
creating a JPEG image, it is possible to configure the level of
Half-duplex - See Full-duplex.
AXIS 211W - Glossary of Terms
compression to use. As the lowest compression (i.e. the highest quality)
results in the largest file, there is a trade-off between image quality and
file size.
NTSC (National Television System Committee) - NTSC is the television
and video standard in the United States. NTSC delivers 525 lines at 60
kbit/s (kilobits per second) - A measure of the bit rate, i.e. the rate at
which bits are passing a given point. See also Bit rate.
OEM (Original Equipment Manufacturer) - This is a designation for
companies that manufacture equipment which is then marketed and
sold to other companies under their own names.
LAN (Local Area Network) - A LAN is a group of computers and
associated devices that typically share common resources within a
limited geographical area.
PAL (Phase Alternating Line) - PAL is the dominant television
standard in Europe. PAL delivers 625 lines at 50 half-frames/second.
Linux - Linux is an open source operating system within the Unix
family. Because of its robustness and availability, Linux has won
popularity in the open source community and among commercial
application developers.
PEM (Privacy Enhanced Mail) - An early standard for securing
electronic mail. The PEM-format is often used for representing an
HTTPS certificate or certificate request.
MAC address (Media Access Control address) - A MAC address is a
unique identifier associated with a piece of networking equipment, or
more specifically, its interface with the network. For example, the
network card in a computer has its own MAC address.
Ping - Ping is a basic network program used diagnostically to check
the status of a network host or device. Ping can be used to see if a
particular network address (IP address or host name) is occupied or not,
or if the host at that address is responding normally. Ping can be run
from, e.g. the Windows Command prompt or the command line in Unix.
Manual iris - This is the opposite to an autoiris, i.e. the camera iris must
be adjusted manually to regulate the amount of light allowed to reach
the image sensor.
Pixel - A pixel is one of the many tiny dots that make up a digital
image. The color and intensity of each pixel represents a tiny area of the
complete image.
Mbit/s (Megabits per second) - A measure of the bit rate, i.e. the rate at
which bits are passing a given point. Commonly used to give the "speed"
of a network. A LAN might run at 10 or 100 Mbit/s. See also Bit rate.
PoE (Power over Ethernet) - Power over Ethernet provides power to a
network device via the same cable as used for the network connection.
This is very useful for IP-Surveillance and remote monitoring
applications in places where it may be too impractical or expensive to
power the device from a power outlet.
Monitor - A monitor is very similar to a standard television set, but
lacks the electronics to pick up regular television signals.
PPP (Point-to-Point Protocol) - A protocol that uses a serial interface
for communication between two network devices. For example, a PC
connected by a phone line to a server.
Motion JPEG - Motion JPEG is a simple compression/decompression
technique for networked video. Latency is low and image quality is
guaranteed, regardless of movement or complexity of the image. Image
quality is controlled by adjusting the compression level, which in turn
provides control over the file size, and thereby the bit rate.
PPTP (Point-to-Point tunneling Protocol) - A protocol (set of
communication rules) that allows corporations to extend their own
corporate network through private "tunnels" over the public Internet. In
this way a corporation can effectively use a WAN (Wide Area Network)
as a large single LAN (Local Area Network). This kind of interconnection
is known as a virtual private network (VPN).
High-quality individual images from the Motion JPEG stream are easily
extracted. See also JPEG.
Megapixel - See Pixel.
MPEG (Moving Picture Experts Group) - The Moving Picture Experts
Group develops standards for digital video and audio compression. It
operates under the auspices of the International Organization for
Standardization (ISO). The MPEG standards are an evolving series, each
designed for a different purpose.
Pre/post alarm images - The images from immediately before and after
an alarm. These images are stored in a buffer for later retrieval.
Progressive scan - Progressive scan, as opposed to interlaced video,
scans the entire picture, line by line every sixteenth of a second. In other
words, captured images are not split into separate fields as in interlaced
MPEG-2 - MPEG-2 is the designation for a group of audio and video
coding standards, and is typically used to encode audio and video for
broadcast signals, including digital satellite and Cable TV. MPEG-2, with
some modifications, is also the coding format used by standard
commercial DVD movies.
Computer monitors do not need interlace to show the picture on the
screen, but instead show them progressively, on one line at a time in
perfect order, i.e. 1, 2, 3, 4, 5, 6, 7 etc., so there is virtually no
"flickering" effect. In a surveillance application, this can be critical
when viewing detail within a moving image, such as a person running.
A high-quality monitor is required to get the best from progressive scan.
See also Interlacing.
MPEG-4 - MPEG-4 is a group of audio and video coding standards and
related technology. The primary uses for the MPEG-4 standard are web
(streaming media) and CD distribution, conversational (videophone), and
broadcast television.
Protocol - A special set of rules governing how two entities will
communicate. Protocols are found at many levels of communication,
and there are hardware protocols and software protocols.
Most of the features included in MPEG-4 are left to individual
developers to decide whether to implement them or not. This means that
there are probably no complete implementations of the entire MPEG-4

set of standards. To deal with this, the standard includes the concept of
"profiles" and "levels", allowing a specific set of capabilities to be
defined in a manner appropriate for a subset of applications.
Proxy server - In an organization that uses the Internet, a proxy server
acts as an intermediary between a workstation user and the Internet.
This provides security, administrative control, and a caching service.
Any proxy server associated with a gateway server, or part of a gateway
server, effectively separates the organization’s network from the outside
network and the local firewall. It is the firewall server that protects the
network against outside intrusion.
Multicast - Bandwidth-conserving technology that reduces bandwidth
usage by simultaneously delivering a single stream of information to
multiple network recipients.
Multiplexer - A multiplexer is a high-speed switch that provides
full-screen images from up to 16 analog cameras. Multiplexers can
playback everything that happened on any one camera with no
interference from the other cameras on the system.
A proxy server receives requests for Internet services (such as web page
requests) from many users. If the proxy server is also a cache server, it
looks in its local cache of previously downloaded web pages. If it finds
the page, it is returned to the user without forwarding the request to the
Internet. If the page is not in the cache, the proxy server, acting as a
client on behalf of the user, uses one of its own IP addresses to request
the page from another server over the Internet. When the requested page
is returned, the proxy server forwards it to the user that originally
requested it.
Network connectivity - The physical (wired or wireless) and logical
(protocol) connection of a computer network or an individual device to a
network, such as the Internet or a LAN.
P-VOP - See VOP.
AXIS 211W - Glossary of Terms
Sockets - Sockets are a method for communication between a client
program and a server program over a network. A socket is defined as
"the endpoint in a connection." Sockets are created and used with a set
of programming requests or "function calls" sometimes called the
sockets application programming interface (API).
Quality of Service (QoS) - QoS provides the means to guarantee a certain
level of a specified resource to selected traffic on a network. Quality can
be defined as, e.g. a maintained level of bandwidth, low latency, no
packet losses, etc.
Referrer - (or HTTP referrer) identifies the address of the resource or the
URL which contains a link to the network camera’s web page.
SSL/TLS (Secure Socket Layer/Transport Layer Security)
Resolution - Image resolution is a measure of how much detail a digital
image can hold: the greater the resolution, the greater the level of detail.
Resolution can be specified as the number of pixel-columns (width) by
the number of pixel-rows (height), e.g. 320x240.
These two protocols (SSL is succeeded by TLS) are cryptographic
protocols that provide secure communication on a network. SSL is
commonly used over HTTP to form HTTPS, as used, e.g. on the Internet
for electronic financial transactions. SSL uses public key certificates to
verify the identity of the server.
Alternatively, the total number of pixels (usually in megapixels) in the
image can be used. In analog systems it is also common to use other
format designations, such as CIF, QCIF, 4CIF, etc.
Subnet/subnet mask - A subnet is an identifiably separate part of an
organization's network. Typically, a subnet may represent all the
machines at one geographic location, in one building, or on the same
local area network (LAN). Having an organization's network divided
into subnets allows it to be connected to the Internet with a single
shared network address.
RTCP (Real-Time Control Protocol) - RTCP provides support for
real-time conferencing of groups of any size within an intranet. This
support includes source identification and support for gateways like
audio and video bridges as well as multicast-to-unicast translators.
The subnet mask is the part of the IP address that tells a network router
how to find the subnet that the data packet should be delivered to. Using
a subnet mask saves the router having to handle the entire 32-bit IP
address; it simply looks at the bits selected by the mask.
RTCP offers quality-of-service feedback from receivers to the multicast
group as well as support for the synchronization of different media
RTP (Real-Time Transport Protocol) - RTP is an Internet protocol for
the transport of real-time data, e.g. audio and video. It can be used for
media-on-demand as well as interactive services such as Internet
Switch - A switch is a network device that connects network segments
together, and which selects a path for sending a unit of data to its next
destination. In general, a switch is a simpler and faster mechanism than
a router, which requires knowledge about the network and how to
determine the route. Some switches include the router function. See also
RTSP (Real Time Streaming Protocol) - RTSP is a control protocol, and
a starting point for negotiating transports such as RTP, multicast and
Unicast, and for negotiating codecs.
TCP (Transmission Control Protocol) - TCP is used along with the
Internet Protocol (IP) to transmit data as packets between computers
over the network. While IP takes care of the actual packet delivery, TCP
keeps track of the individual packets that the communication (e.g.
requested a web page file) is divided into, and, when all packets have
arrived at their destination, it reassembles them to re-form the complete
RTSP can be considered a "remote control" for controlling the media
stream delivered by a media server. RTSP servers typically use RTP as
the protocol for the actual transport of audio/video data.
Router - A device that determines the next network point to which a
packet should be forwarded on its way to its final destination. A router
creates and/or maintains a special routing table that stores information
on how best to reach certain destinations. A router is sometimes
included as part of a network switch. See also switch.
TCP is a connection-oriented protocol, which means that a connection is
established between the two end-points and is maintained until the data
has been successfully exchanged between the communicating
Server - In general, a server is a computer program that provides
services to other computer programs in the same or other computers. A
computer running a server program is also frequently referred to as a
server. In practice, the server may contain any number of server and
client programs. A web server is the computer program that supplies the
requested HTML pages or files to the client (browser).
Telnet - Telnet is a simple method with which to access another
network device, e.g. a computer. The HTTP protocol and the FTP
protocols allow you to request specific files from remote computers, but
do not allow you logon as a user of that computer. With Telnet, you log
on as a regular user with whatever privileges you may have been
granted for specific applications and data residing on that computer.
Sharpness - This is the control of fine detail within a picture. This
feature was originally introduced into color TV sets that used notch filter
decoders. This filter took away all high frequency detail in the black and
white region of the picture. The sharpness control attempted to put some
of that detail back in the picture. Sharpness controls are mostly
superfluous in today's high-end TVs. The only logical requirement for it
nowadays is on a VHS machine.
TVL (TV Lines) - A method of defining resolutions in analog video.
UDP (User Datagram Protocol) - UDP is a communications protocol
that offers limited service for exchanging data in a network that uses
the Internet Protocol (IP). UDP is an alternative to the Transmission
Control Protocol (TCP). The advantage of UDP is that it is not required to
deliver all data and may drop network packets when there is, e.g.
network congestion. This is suitable for live video, as there is no point in
re-transmitting old information that will not be displayed anyway.
Simplex - In Simplex operation, a network cable or communications
only send
one direction.
User’s inGuide
SMTP (Simple Mail Transfer Protocol) - SMTP is used for sending and
receiving e-mail. However, as it is "simple," it is limited in its ability to
queue messages at the receiving end, and is usually used with one of two
other protocols, POP3 or IMAP. These other protocols allow the user to
save messages in a server mailbox and download them periodically from
the server.
Unicast - Communication between a single sender and a single receiver
over a network. A new connection is established for each new user.
URL (Uniform Resource Locator) - An "address" on the network.
USB - (Universal Serial Bus) A plug-and-play interface between a
computer and peripheral devices, e.g. scanners, printers, etc.
SMTP authentication is an extension of SMTP, whereby the client is
required to log into the mail server before or during the sending of
email. It can be used to allow legitimate users to send email while
denying the service to unauthorized users, such as spammers.
Varifocal lens - A varifocal lens provides a wide range of focal lengths,
as opposed to a lens with a fixed focal length, which only provides one.
VAPIX - AXIS VAPIX is considered to be the global application
programming interface (API) standard, in the rapidly growing field of
Network Video based on IP.
SNMP (Simple Network Management Protocol) - SNMP forms part of
the Internet Protocol suite, as defined by the Internet Engineering Task
Force. The protocol can support monitoring of network-attached devices
for any conditions that warrant administrative attention.
VPN (Virtual Private Network) - This creates a secure "tunnel"
between the points within the VPN. Only devices with the correct "key"
will be able to work within the VPN. The VPN network can be within a
AXIS 211W - Glossary of Terms
company LAN (Local Area Network), but different sites can also be
connected over the Internet in a secure way. One common use for VPN is
for connecting a remote computer to the corporate network, via, e.g. a
direct phone line or via the Internet.
VOP (Video Object Plane) - A VOP is an image frame in an MPEG-4
video stream. There are several types of VOP:
- An I-VOP is complete image frame.
- A P-VOP codes the differences between images, as long as it is more
efficient to do so. Otherwise it codes the whole image, which may also
be a completely new image.
WAN (Wide-Area-Network) - Similar to a LAN, but on a larger
geographical scale.
W-LAN (Wireless LAN) - A wireless LAN is a wireless local area
network that uses radio waves as its carrier: where the network
connections for end-users are wireless. The main network structure
usually uses cables.
Web server - A Web server is a program, which allows Web browsers
to retrieve files from computers connected to the Internet. The Web
server listens for requests from Web browsers and upon receiving a
request for a file sends it back to the browser.
The primary function of a Web server is to serve pages to other remote
computers; consequently, it needs to be installed on a computer that is
permanently connected to the Internet. It also controls access to the
server whilst monitoring and logging server access statistics.
WEP (Wireless Equivalent Privacy) - A wireless security protocol,
specified in the IEEE 802.11 standard, which is designed to provide a
wireless local area network (WLAN) with a level of security and privacy
comparable to that usually expected of a wired LAN. Security is at two
different levels; 40-bit and 104-bit encryption. The higher the bit
number, the more secure the encryption.
WINS (Windows Internet Naming Service) - Part of the Microsoft
Windows NT Server, WINS manages the association of workstation
names and locations with IP addresses, without the user or administrator
having to be involved in each configuration change.
WPA-/WPA2-Enterprise - This wireless encryption method provides
stronger data protection for multiple users and larger networks.
Unauthorzed network access is prevented by verifing users through a
WPA-/WPA2-PSK (Wi-Fi Protected Access - Pre-Shared Key) - This
wireless encryption method uses a pre-shared key (PSK) for key
management. Keys can usually be entered as manual hex values, as
hexadecimal characters, or as a Passphrase. WPA-PSK provides a greater
degree of security than WEP.
Zoom lens - A zoom lens can be moved (zoomed) to enlarge the view of
an object to show more detail.
