14 AXIS 210A/211A - Video Streams
Video Streams
The AXIS 210A/211A provides several different image and video formats. You choose the
type depending on your requirements and the properties of your network.
The Live View page in the AXIS 210A/211A provides access to Motion JPEG and MPEG-4
video streams, and to single JPEG images. Other applications and clients can also access
these video streams/images directly, without going via the Live View page.
Video Stream Types
Motion JPEG
This format uses standard JPEG still images in the video stream. These images are then
displayed and updated to create a stream that shows constantly updated motion.
The Motion JPEG stream uses considerable amounts of bandwidth, but also provides
excellent image quality and access to every individual image contained in the stream.
Note also that multiple clients accessing Motion JPEG streams can use different image
This is a video compression standard that makes good use of bandwidth, and which can
provide high-quality video streams at less than 1 Mbit/s.
The MPEG-4 standard provides scope for a large range of different coding tools for use by
various applications in different situations, and the AXIS 210A/211A provides certain
subsets of these tools. These are represented as Video object types, which are selected for
use with different viewing clients. The supported video object types are:
• Simple - sets the coding type to H.263, as used by QuickTime™.
• Advanced Simple - sets the coding type to MPEG-4 Part 2, as used by AMC
(AXIS Media Control).
When using MPEG-4 it is also possible to control the bit rate, which in turn allows control
of bandwidth usage. CBR (Constant Bit Rate) is used to achieve a specific bit rate by
varying the quality of the MPEG-4 stream. When using VBR (Variable Bit Rate), the quality
of the video stream is kept as constant as possible, at the cost of a varying bit rate.
Notes: MPEG-4 is licensed technology. The AXIS 210A/211A includes one viewing client license. Installing additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses, contact your
Axis reseller.
All clients viewing the MPEG-4 stream must use the same set of coding tools.
AXIS 210A/211A - Video Streams
MPEG-4 protocols and communication methods
To deliver live streaming video over IP networks, various combinations of transport
protocols and broadcast methods are employed.
• RTP (Realtime Transport Protocol) is a protocol that allows programs to manage
the real-time transmission of multimedia data, via unicast or multicast.
• RTSP (Real Time Streaming Protocol) serves as a control protocol, to negotiate
which transport protocol to use for the stream. RTSP is thus used by a viewing
client to start a unicast session, see below.
• UDP (User Datagram Protocol) 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 network congestion. This is suitable for live video, as there is no
point in re-transmitting old information that will not be displayed anyway.
• Unicasting is communication between a single sender and a single receiver over a
network. The video stream goes independently to each user and each user gets
their own stream. With unicasting that if one stream fails, it only affects one user.
• Multicast is bandwidth - conserving technology that reduces bandwidth usage by
simultaneously delivering a single stream of information to multiple network
recipients. This technology is used primarily on delimited networks (intranets), as
users need uninterrupted data flow and should not rely on network routers.
How to stream MPEG-4
Deciding on the combination of protocols and methods to use depends on your viewing
requirements, and on the properties of your network. Setting the preferred method(s) is
done in the control applet for AMC, which is found in the Windows Control Panel. When
this has been set, AMC will test all the selected methods in the specified order, until the
first functioning one is found.
This method (actually RTP over UDP and RTSP over TCP) should be your first consideration
for live video, especially when it is important to always have an up-to-date video stream,
even if some images do get dropped. This can be configured as multicast or unicast.
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 the Internet.
Unicasting should be used for video-on-demand broadcasting, so that there is no video
traffic on the network until a client connects and requests the stream. However, as more
unicast clients connect, the traffic on the network will increase and may cause congestion.
Although there is a maximum of 20 unicast viewers, note that all multicast users combined
16 AXIS 210A/211A - Video Streams
count as 1 unicast viewer.
This unicast method is RTP tunneled over RTSP. This can be used to exploit the fact that it
is relatively simple to configure firewalls to allow RTSP traffic.
These two methods can also be used to traverse firewalls. Firewalls are commonly
configured to allow the HTTP protocol, thus allowing RTP to be tunneled.
AXIS Media Control
The recommended method of accessing live video from the AXIS 210A/211A is to use the
AXIS Media Control (AMC) in Microsoft Internet Explorer for Windows. This ActiveX
component is automatically installed on first use, after which it can be configured by
opening the AMC Control Panel applet from the Windows Control Panel. Alternatively,
right-click the video image in Internet Explorer.
Other methods of accessing the video stream
Video/images from the AXIS 210A/211A can also be accessed in the following ways:
• If supported by the client, the AXIS 210A/211A can use Motion JPEG server push
to display video. This option maintains an open HTTP connection to the browser
and sends data as and when required, for as long as required.
• As single JPEG images in a browser. Enter the path:
http://<IP address>/axis-cgi/jpg/image.cgi?resolution=320x240
• Windows Media Player. This requires AMC and the MPEG-4 decoder to be
installed. The paths that can be used are listed below in the order of preference.
• Unicast via RTP: axrtpu://<IP address>/mpeg4/media.amp
• Unicast via RTSP: axrtsp://<IP address>/mpeg4/media.amp
• Unicast via RTSP, tunneled via HTTP: axrtsphttp://<IP
• Unicast via RTSP, tunneled via HTTPS: axrtsphttps://<IP
• Multicast: axrtpm://<IP address>/mpeg4/media.amp
Other MPEG-4 clients
Although it may be possible to use other clients to view the MPEG-4 stream, this is not
guaranteed by Axis. For some other clients, such as QuickTime™ the Video Object Type
must be set to Simple. It may also be necessary to adjust the advanced MPEG-4 settings.
To assess the video stream from QuickTime™ the following path can be used:
AXIS 210A/211A - Video Streams
rtsp://<IP address>/mpeg4/media.amp
This path is for all supported methods, and the client negotiates with the AXIS 210A/211A
to determine exactly which transport protocol to use.
Audio Stream Types
The stream types for audio are:
• G.711 - International standard for encoding wired-telephone audio. Uses PCM
samples to compress audio where higher signal values are compressed more than
lower values. In Axis products, this sets the coding type to μ-law 64 kbit/s.
• G.726 - Uses PCM samples to code the difference between samples (ADPCM).
Reduces bandwidth without losing too much useful audio. In Axis products, this
sets the coded bit rate to 24 or 32 kbit/s.
All stream types are ITU-T standards and operate on frequencies up to 4 kHz.
Audio transmission methods
The audio stream can be accessed in the Live View page via Motion JPEG or MPEG-4.
Using Motion JPEG
The basic audio transmission method used in conjunction with Motion JPEG video
streaming is transmission over HTTP. The video and audio streams are not synchronized
when using Motion JPEG, so the streams may be slightly out of sync. The latency in any
stream should be low, but this depends on the network infrastructure.
Using MPEG-4
When using MPEG-4, audio is streamed using the same protocol as the video stream. When
audio is transmitted using MPEG-4, the AXIS 210A/211A sends synchronization
information along with the streams to the client performing the synchronization.
Note: Audio is streamed from the client to the server over HTTP when using Motion JPEG and MPEG-4.
Accessing the Audio Streams
In addition to accessing audio in the Live View page using AMC, audio from the AXIS
210A/211A can also be accessed in the following ways:
You can read about accessing audio for the other protocols through the VAPIX Application
Programming Interface (API) at
QuickTime/Windows Media Player
It is possible to use QuickTime and Windows Media Player to listen to the audio stream
using the same methods to access video streams.

AXIS 210A/211A - Video & Image settings
Camera 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 Priority, Max exposure time, and Max gain
settings until you achieve an acceptable image quality at the required frame rate.
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
increase image noise.
Increasing the Max exposure time increases the quality of the image, but decreases the
frame rate. There may also be increased motion blur.
Max gain, measured in decibels (dB), describes the amount of amplification applied to the
visual information in the image. A high level of amplification provides viewable images in
very low light, but increases image noise.
To prioritize image quality, choose Prioritize image quality from the Exposure priority
drop-down box, 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 framerate from the Priority drop-down
box and reduce the Max exposure time. The image darkens considerably, but the frame
rate is maintained. To increase image brightness increase Max gain, but this increases
image noise.
Please refer to the online help
for more information.
24 AXIS 210A/211A - Video & Image settings
MPEG-4 Settings
Tools for adjusting the MPEG-4 settings and for controlling the video bit rate.
The MPEG-4 standard provides many different tools for various applications in different
situations. As most MPEG-4 clients do not support all of these tools, it is usual to instead
define and use subsets for different clients or groups of clients. These settings allow you to
define the type of viewing client to use.
Adjusting the maximum bit rate and setting it to a variable or constant is a good way of
controlling the bandwidth used by the MPEG-4 video stream. For more information on
these advanced settings, please see Video Streams, on page 14, and the online help
Sometimes the image size is large due to low light or complex scenery. Adjusting the
maximum frame size helps to control the bandwidth and storage used by the MJPEG video
stream in these situations. Defining the frame size as Unlimited provides consistently good
image quality at the expense of increased bandwidth and storage usage during low light.
Limiting the frame size optimizes bandwidth and storage usage, but gives poor image
quality. To prevent increased bandwidth and storage usage, the maximum frame size
should be set to an optimal value.
AXIS Media Control
The AXIS Media Control (AMC) is installed automatically the first time the camera is
accessed from a browser. The AMC control panel can be opened by right-clicking on the
video image in the Live View web page. The AMC control panel can be used to configure
various network, video and audio settings such as:
AXIS 210A/211A - Video & Image settings
• Network reconnection strategy, multicast network interface, and MPEG-4 connection order
• MPEG-2 and MPEG-4 video processing settings and default video decoder setting
• Audio start settings and talk button options
• Video snapshot and recording settings
• Pan Tilt Zoom (PTZ) settings such as joy stick settings and PTZ mode settings

26 AXIS 210A/211A - Audio
The AXIS 210A/211A can transmit audio to other clients using an external microphone
and can play audio received from other clients by attaching a speaker. The Setup page for
the AXIS 210A/211A has an additional menu item called Audio, which allows different
audio configurations to be set up, such as full duplex, half duplex and simplex.
Note: The speaker attached to the audio output of the AXIS 210A/211A must have a built-in amplifier, such as PC

Audio Settings
This section describes how to configure basic audio settings for the AXIS 210A/211A, e.g.
set the communication mode and adjust the sound levels in the microphone and speaker
connected to the camera.
Enable Audio
Check this box to enable audio in the AXIS 210A/211A.
Audio Channels
There are two mono audio channels between the AXIS 210A/211A and other clients, one
for receiving audio and one for transmitting audio. Each audio channel can be turned on
or off, which means that there are four audio mode options that can be used.
AXIS 210A/211A - Audio
Full-duplex mode means you can transmit and receive audio (talk and listen) at the same
time, without having to use any of the controls. This is just like having a telephone
conversation. The only controls you may wish to use are the mute buttons to turn off the
sound, and the sliders, to adjust the input/output volume levels. This mode requires the
client PC to have a sound card with full-duplex audio support. If your available bandwidth
is 0.2 Mbit/s or less, using Half-duplex mode is recommended instead.
Half-duplex mode also transmits and receives audio in both directions, but only in one
direction at a time. This means that you must select when to receive or transmit audio with
the help of the push-to-talk button. To speak, press and hold the button (check that the
microphone is not muted). When finished, release the button. You will now receive audio
from the other end of the connection.
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.
Note that the push-to-talk button is configured from AMC; see AXIS Media Control, on
page 24. It is also possible to configure the push-to-talk button so that it toggles between
the speaking and listening modes. Half-Duplex mode is best if you only have limited
bandwidth available.
When selecting the Simplex - Network Camera speaker only mode, the speaker connected
to the camera plays audio, but no audio is transmitted from the camera to other web
clients. This could be used to 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
210A/211A to web clients. It does not receive audio from any other web clients. This can
be used in remote monitoring, and web attractions to provide live audio and video of a
monitored situation.
Audio Input
Audio from an external microphone or a line source can be connected to the Line/Mic in
jack of the AXIS 210A/211A. The audio source can be set to Internal microphone, External
microphone or Line. If you are using a microphone, the input sensitivity can be set to
High or Low. See Technical Specifications, on page 57 for the exact maximum levels.
The Enable microphone power option provides DC power for an external microphone. If
using a small electret condenser microphone such as a clip-on microphone or a PC
microphone, this option needs to be enabled.
To use a high impedance dynamic microphone, DC power should not be enabled. DC power
will not harm the microphone, but if you are uncertain, try switching it off and on. The
default value is DC power enabled. 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.
28 AXIS 210A/211A - Audio
If there are problems with the sound input being too low or high, adjust the input gain for
the microphone attached to the AXIS 210A/211A.
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 210A/211A.
When satisfied with the settings, click Save, or click Reset to revert to the previously saved
Advanced Audio Settings
The Audio Quality Settings allow you to fine-tune the internal or external microphone
connected to the AXIS 210A/211A to suit your environment.
Enable speech filter improves the sound quality when the microphone is placed close to
the person talking and can also help reduce background noise. The filter cuts the lowest
and the highest frequencies. The bypass frequency range is approximately 250Hz to
3700Hz (measured at -10dB cut-off break points).
Enable echo cancellation - if audio from the speaker is captured by the microphone, this
produces an echo. Enable this option to reduce acoustic echoing.
Noise canceling is a way of reducing the background noise when there is no useful audio
present. A typical application could be that the camera is set up in a noisy environment,
and you are only interested in hearing the sound from the AXIS 210A/211A when
someone is speaking close to the microphone.
There are two adjustable parameters available for noise cancellation:
• Noise canceller threshold value
• Noise canceller attenuation
AXIS 210A/211A - Audio
When the incoming sound is louder than the threshold it passes without being affected.
When lower than the threshold, the incoming sound is reduced by a certain attenuation
factor. The threshold level should be set higher than the background noise, but lower than
the useful audio.
The noise canceller threshold value can be set to High, Medium High, Medium low or
Low. A lower threshold allows most audio to pass; only the weakest background noise is
reduced. A higher threshold makes the noise canceller act on even stronger background
noise. At the maximum level - High - there is a risk of reducing useful audio as well.
There is thus always a trade-off between noise canceling and sound quality. In other
words, increasing the noise canceller attenuation results in deterioration in sound quality.
To adjust the threshold and attenuation to an optimum level, change the levels and then
listen to the result.
AXIS Media Control (AMC)
The AMC control panel can also be used to configure various audio settings, such as start
settings and talk button options. The AMC control panel can be opened by right-clicking
on the video image in the Live View web page. Please see the readme file included in the

performs certain actions.
Example: If somebody passes in
front of the camera and an event that
uses motion detection has been configured to act on this, the camera can
record and save images to an FTP
server, and/or send a notification e-mail to a pre-configured e-mail address with a pre-configured message. Images
can be sent as e-mail attachments.
Triggered Event
A triggered event can be activated by:
a push button connected to the camera’s input port
a manual action such as clicking the trigger button in the web interface
detected movement in a configured motion detection window
on restart (reboot) after power loss
How to set up a triggered event
This example describes how to set up the camera to upload images when the main door is
1. Click Add triggered on the Event Types page.
2. Enter a descriptive name for the event, such as Main door open.
3. Set the priority - High, Normal or Low (see the online help).
4. Set min time interval between triggers - this is the minimum time period that
the event type must wait after a trigger and before the next trigger. The interval
commences as soon as the first trigger occurs. The shortest possible interval is 1
second and the longest is 23 hours, 59 minutes and 59 seconds. If you do not
want to not use a minimum interval, set this option to 00:00:00
5. Set the Respond to Trigger... parameters to define when the event is active, such
as only after office hours.
6. Select the trigger alternative from the Triggered by... drop-down list. For example
select Input ports, for a sensor connected to the door.
7. Set the When Triggered... parameters, that is, define what the camera does if the
main door is opened, such as upload images to an FTP server or send an e-mail
8. Click OK to save the event in the Event Types list.
38 AXIS 210A/211A - Event Configuration
Please see the online help
for descriptions of each available option.
Note: Up to 10 event types can be configured in the cameras, and up to 3 of these can be configured to upload
images. Files names can be formatted according to specific requirements. See File Naming & Date/Time
Formats online help.
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. 5 seconds before and/or after a door was opened. Check the
Upload images checkbox under Event Types > Add Triggered... > Triggered by... . All
uploaded images are JPEG images.
Include pre-trigger buffer - images stored internally in the server 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.
Notes: Pre-trigger and Post-trigger buffers are 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 is reduced and individual images may be missing. If this occurs, an entry is 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 is the
best possible, but might not be as high as specified, especially if uploading via a slow
Scheduled Event
A Scheduled event can be activated at preset times, in a repeating pattern on selected
Configuration example:
1. Click Add scheduled on the Event types page.
2. Enter a descriptive name for the event, such as “Scheduled e-mail upload.”
3. Set the priority (High, Normal or Low).
4. Set the Activation Time parameters (24h clock) defining when the event is active,
e.g. start on Sundays at 13.00 for a duration of 12 hours.
5. Set the When Activated... parameters, defining what the camera does at the
specified time, such as send uploaded images to an e-mail address.

Camera Tampering
The camera tampering application generates an alarm whenever the camera is
repositioned, or when the lens is covered, sprayed or severely put out of focus.
The Minimum duration parameter defines the time that must elapse before the alarm goes
off after the tampering. This helps prevent false alarms.
Check the Alarm for dark images box if there should be an alarm when the camera lens is
sprayed and the image is dark.
Motion Detection
Motion detection is used to generate an alarm whenever movement occurs (or stops) in the
video image. A total of 10 Include and/or Exclude windows can be configured.
• Included windows target specific areas within the whole video image
• Excluded windows define areas within an Include window that should be ignored
(areas outside Include windows are automatically ignored)
Once configured, the motion detection windows appear in the list of available triggers, for
triggering events. See “How to set up a triggered event” on page 37.
Note: Using the motion detection feature may decrease the camera’s overall performance.
Configuring Motion Detection
1. Click Motion Detection in the Event Configuration menu.
40 AXIS 210A/211A - Event Configuration

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 assigning user names and
passwords. It is also possible to allow anonymous viewer login, which means that anybody
may access the Live View page.
The AXIS 210A/211A Network Camera supports several methods of user authentication:
HTTP Basic Authentication - This authenticates the user by requesting a user name and a
password. The exchange of network credentials is in simple base64 coding and is not
HTTP Digest Authentication - This method also requests a user name and password, but
the exchange of credentials is encrypted, which secures it against eavesdropping.
User List - 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 options and can determine the registration
of all other users.
User Settings - check the relevant checkboxes to enable:
• Anonymous viewer login - allows any viewer direct access to the Live View
• Maximum number of simultaneous viewers limited to - 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 one viewer.)
IP Address Filtering
Enable IP Address Filtering: To allow or deny access to the AXIS 210A/211A Network
Camera check the box Enable IP address filtering. Once enabled, the IP addresses in the
list are allowed or denied access according to the choice made in the drop-down list
Allow/Deny the following IP addresses.
The administrator can add up to 256 IP address entries to the list (a single entry can
contain multiple IP addresses). The users from these IP addresses need to be specified in the
user list with the appropriate access rights. This is done from Setup > System Options >
Security > Users.

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 210A and the AXIS 211A both support 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 is implemented after the installation of a signed certificate issued by a certificate
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

IEEE 802.1x
IEEE 802.1x is 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).
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.
AXIS 210A/211A - System Options
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 Free Radius 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
Axis video device
Q: Certificate OK?
Q: Certificate OK?
Authority (CA)
Protected network
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 switch.
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) is an 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 situations.
CA servers
In cryptography, a Certification Authority (CA) is an entity that provides signed digital
certificates for use by other parties, and thus acts a trusted third party.
There are many commercial CAs that charge for their services. Institutions and
governments may have their own CA, and there are free CAs available.

Basic TCP/IP Settings
IP Address Configuration
Your Axis network camera supports both IP version 4 and IP version 6. Both versions may
be enabled simultaneously, and at least one version must always be enabled.
When using IPv4, the IP address can be set automatically via DHCP, or a static IP address
can be set manually.
If IPv6 is enabled, your camera will receive an IP address according to the configuration in
the network router.
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
210A/211A by host name which is always the same, regardless of the IP address.
Options for notification of IP address change - if the IP address for the video server
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 - The AXIS Internet Dynamic DNS Service can
provide your Axis product with its own URL (web address), which can then be used to
access it over the Internet. The product can be unregistered from the service at any time.
To do this click Settings... and follow the instructions. For more information, please refer

Link-Local IPv4 Address
This is enabled by default and assigns the AXIS 210A/211A an additional IP address for
use with UPnP™. The AXIS 210A/211A 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 simple security port mapping.
The default HTTPS port number (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 attempt to access the private network
(LAN) from the public network/Internet.
48 AXIS 210A/211A - System Options
Use NAT traversal when your AXIS 210A/211A 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 is
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.
Enable/Disable - When enabled, the AXIS 210A/211A attempts 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 > UPnP).
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 210A/211A automatically searches for NAT
routers on your network. If more than one router is found, the default router is 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 is
automatically selected when NAT traversal is enabled.
• 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 you attempt to manually enter a port that is already in use, another available port us
automatically selected.
• When the port is selected automatically it is displayed in this field. This can be changed
by entering a new port number and clicking Save.
The FTP server running in the AXIS 210A/211A enables the upload of e.g. new firmware,
user applications, etc. Check the box to enable the service.

SOCKS is a network proxy protocol. The cameras 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 camera is located on a local network behind a firewall, but notifications, uploads, and
alarms need to be sent to a destination outside the local network (such as to the Internet).
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 a maintained level of
bandwidth, low latency, no packet losses, and so on. 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
50 AXIS 210A/211A - System Options
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
following types of traffic are marked:
• live video
• live audio
• event/alarm traffic
• management network traffic.
QoS 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 hex form, but saved values are always
shown in decimal.

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 the group of network devices using SNMP.
• SNMP V3 - provides encryption and secure passwords. HTTPS must be enabled.
AXIS 210A/211A - System Options
The cameras includes support for UPnP™. UPnP™ is enabled by default, and the network
camera then is automatically detected by operating systems and clients that support this

Transistor Output
With a maximum load of 100mA and a maximum voltage of 24V DC, this output
has an open-collector NPN transistor with the emitter connected to pin 1 (GND).
If used with an external relay, a diode must be connected in parallel with the load,
for protection against voltage transients.
Digital Input
Connect to GND to activate, or leave floating (or unconnected) to deactivate.
Auxiliary DC Power Input
7-20 VDC/max 5W. Electrically connected in parallel with the PS-K power
connector, this pin provides an auxiliary connector for mains power to the unit. If
the unit is powered via this pin, a fuse should be used (rating: 1A Slow).
This pin can also be used to power auxiliary equipment, max 100mA, but note that
this is not possible when the AXIS 210A/AXIS 211/211A is powered by PoE.

General performance considerations
When setting up your system, it is important to consider how various settings and
situations affect performance. Some factors affect the amount of bandwidth (the bit rate)
required, others can affect the frame rate, and some affect both. If the load on the CPU
reaches its maximum, this also affects 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, etc.) by different clients. Frame rate and bandwidth affected.
• Accessing both Motion JPEG and MPEG-4 video streams simultaneously. Frame
rate and bandwidth affected.
• 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.
Optimizing your system
To see the bandwidth and frame rate currently required by the video stream, the AXIS
210A/211A provides a tool that can be used to display these values directly in the video
AXIS 210A/211A - Technical Specifications
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.
The figures displayed here are the values as delivered by the camera. If other restrictions are currently in
force, (e.g. bandwidth limitation) these values might not correspond to those actually received by the client.
For Motion JPEG, these values are accurate as long as no frame rate limit has been specified.
Frame rates - Motion JPEG and MPEG-4
The following table show typical frame rates in frames/second (fps) for Motion JPEG and
MPEG-4 video streams from the AXIS 210A/211A.
Note that these values are guidelines only - actual values may vary.
Motion JPEG settings:
• Viewing in AMC
• Compression level = 30%
MPEG-4 settings:
Viewing in AMC
Compression level = 30%
Video Object Type = Advanced Simple
GOV length = 8
GOV structure = IP*
Frame rates
Motion JPEG
Note: Setting the GOV structure to use “I-frames only” will increase the frame rate at the expense of the bit rate.
* The GOV structure can take two different forms; I and IP. The I-structure sends complete images
(I-images) whereas the IP-structure mostly sends the differences compared with the previous image
(P-images) and only a few I-images. The IP-structure requires much less bandwidth than the I-structure.
62 AXIS 210A/211A - Technical Specifications
As there are many factors that affect bandwidth, it is very difficult to predict the required
amounts. The settings that affect bandwidth are:
• the image resolution
• the image compression
• the frame rate
• the MPEG-4 object type
• the MPEG-4 GOV structure
• the maximum exposure time.
There are also factors in the monitored scene that affect the bandwidth. These are:
• the amount of motion
• the image’s complexity
• the lighting conditions.
For MPEG-4, if there is only limited bandwidth available, and if this is more important
than the image quality, using a constant bit rate (CBR) is recommended. Use a variable bit
rate (VBR) if the image quality needs to be maintained at a higher level. With multiple
viewers, and If supported on the network, consider using MPEG-4 multicasting, as the
bandwidth consumption is much lower.

64 AXIS 210A/211A - Troubleshooting
Checking the Firmware
One of your first actions when troubleshooting a problem should be to check the 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
Upgrading the Firmware
Firmware is software that determines the functionality of the camera. When you upgrade
the firmware with a file from the Axis Web site, your camera receives 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 are saved when the firmware is upgraded (providing the features
are available in the new firmware) although this is not guaranteed by Axis Communications. Always read
the instructions and release notes available with each new release, before upgrading the firmware.
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.
Notes: 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.
Emergency Recovery Procedure
If power or the network connection to the camera is lost during the upgrade, the process
fails and the unit becomes unresponsive. A flashing red Status LED indicates a failed
upgrade. To recover the unit, follow the steps below. The serial number is found on the
label attached to the bottom of the camera.
AXIS 210A/211A - Troubleshooting
1. Unix/Linux - From the command line, type the following:
arp -s <IP address of camera> <Serial number> temp
ping -s 408 <IP address of camera>
Windows - From a command/DOS prompt, type the following:
arp -s <IP address of camera> <Serial number>
ping -l 408 -t <IP address of camera>
2. If the unit does not reply within a few seconds, restart it and wait for a reply.
Press CTRL+C to stop Ping.
3. Open a browser and type in the camera’s IP address. In the page that appears, use
the Browse button to select the upgrade file to use, e.g. axis210.bin or

Symptoms, Possible Causes and Remedial Actions
Problems setting the IP address
When using ARP/Ping.
Try the installation again. The IP address must be set within two minutes after power has
been applied to the camera. Ensure the Ping length is set to 408. See the Installation
The camera is located on a different
If the IP address intended for the camera and the IP address of your computer are located
on different subnets, you will not be able to set the IP address. Contact your network
administrator to obtain an appropriate IP address.
The IP address is being used by another Disconnect the camera from the network. Run the Ping command. (In a Command/DOS
window, type ping and the IP address of the unit).
If you receive: Reply from <IP address>: bytes = 32; time = 10 ms..... - this means that
the IP address may already be in use by another device on your network. You must obtain
a new IP address and reinstall the unit.
If you see: Request timed out - this means that the IP address is available for use with
your camera. In this case, check all cabling and reinstall the unit.
Possible IP address conflict with
another device on the same subnet.
The static IP address in the camera is used before the DHCP server sets a a dynamic
address. This means that if the same default static IP address is also used by another
device, there may be problems accessing the camera. To avoid this, set the static IP
address to
The camera cannot be accessed from a browser
The IP address has been changed by
1) Move the camera to an isolated network or to one with no DHCP or BOOTP server. Set
the IP address again, using the AXIS IP Utility (see the Installation Guide) or the ARP/Ping
2) Access the unit and disable DHCP in the TCP/IP settings. Return the unit to the main
network. The unit now has a fixed IP address that will not change.
3) As an alternative to 2), if dynamic IP address via DHCP or BOOTP is required, select the
required service and then configure IP address change notification from the network settings. Return the unit to the main network. The unit now has a dynamic IP address, but
will notify you if the address changes.
Proxy server.
If using a proxy server, try disabling the proxy setting in your browser.
Other networking problems.
Test the network cable and connectors by connecting it to another network device, then
Ping that device from your workstation. See the instructions above.

which a packet should be forwarded on its way to its final
destination. A router is often included as part of a network
switch (see below).
RTP- Real-Time Transfer Protocol. A transfer protocol
designed for delivery of live contents, e.g. MPEG-4.
Simplex - In simplex operation, a network cable or
communications channel can only send information in one
SMTP - A common e-mail protocol.
SNMP - Simple Network Management Protocol. An
application layer protocol that facilitates the exchange of
management information between network devices. It is
part of the Transmission Control Protocol/Internet Protocol
(TCP/IP) protocol suite.
Subnet Mask - An IP address consists of two components:
the network address and the host address. “Subnetting’
enables a network administrator to further divide the host
part of the address into two or more subnets. The subnet
mask identifies the subnet to which an IP address belongs.
Switch - Whilst a simple hub transmits all data to all
devices connected to it, a switch only transmits the data to
the device it is specifically intended for.
TCP/IP - Transmission Control Protocol/Internet Protocol. A
suite of network protocols that determine how data is
transmitted. TCP/IP is used on many networks, including the
Internet. TCP keeps track of the individual packets of
information and IP contains the rules for how the packets
are actually sent and received.
URL - Uniform Resource Locator. An “address" on the
Varifocal - A varifocal lens provides a wide range of focal
lengths, as opposed to a lens with a fixed focal length,
which only provides one.
WAN - Wide-Area-Network. Similar to a LAN, but on a
larger geographical scale.
Web server - A program on a computer (server) providing
the resources (e.g. web pages) requested by the user (client).
