AXIS 262+ Product Description
Product Description
The AXIS 262+ Network Video Recorder, together with Axis network cameras, offers a
comprehensive surveillance solution for detecting shoplifters, reducing false alarms,
increasing personnel safety or viewing your premises remotely.
Easy to install and use, the AXIS 262+ is a complete recording solution that connects
directly to your network and is manageable remotely via a local area network or the
Internet. It enables simultaneous recording and remote access to live views and playback
of recorded images from up to eight Axis network cameras. Scheduled and triggered
recordings can be performed at a recording speed of up to 240 frames per second in QVGA
(320x240 pixels) and CIF (352x240 in NTSC, 352x288 in PAL).
The AXIS 262+ is ideal for storing video at up to megapixel resolution. There is no
degradation in video quality, as it will always give the same image quality as the original
image from the camera or video server. A 250 GB hard disk allows you to store, for
instance, 13 days of VGA (640x480) resolution at one frame per second from eight video
channels.
The main features of the AXIS 262+ are:
• Records video from up to eight network cameras at up to megapixel resolution.
• Easy to install, use and manage.
• Enables simultaneous recording and remote access to recorded video, as well as
live viewing.
• Records at up to 120 frames per second at VGA (640x480 pixels) or 4CIF
(704x480 NTSC, 704x576 PAL).
• Recording can be started by an alarm from a camera or by a trigger from a digital
input on the AXIS 262+.
• The frame rate for alarm recordings can be specified independently from the
frame rate of scheduled recordings. Different video sources can have different
frame rates for scheduled recordings.
• 250 GB hard disk with anti-vibration.

Although the AXIS 262+ records images at the highest frame rate the network camera or
video server can deliver, this might actually be lower than the value set in the Frame rate
option. This can happen if there is only limited bandwidth available, or if the camera/video
server is limiting the frame rate.
If the frame rates for manual and scheduled recording are different, the AXIS 262+ records
data at the frame rate set for the camera in the manual recording. Alarm recordings always
use the frame rates specified when configuring an alarm recording.
Set manual recording frame rate

Troubleshooting
To solve a problem with the AXIS 262+, consult the list of symptoms and corrective
actions, or see the information on upgrading the firmware.
Resetting the AXIS 262+
If you are experiencing a problem with the AXIS 262+, there are a few options available to
correct the problem. The first option to try would be to restart the unit. Resetting the AXIS
262+ to the factory default settings should only be used if all other options fail. The
Restart, Restore and Default options can be accessed by clicking
> Maintenance.
There is a button on the rear of the AXIS 262+ for restoring the factory default settings.
Restart - The Restart button on the Maintenance page will restart the AXIS 262+, no
settings will be lost as a result.
Restore - If the unit does not behave as expected, use the Restore button on the
Maintenance page to reset all parameters, except the IP parameters, to their original
factory settings.
Default - The Default button on the Maintenance page is similar to Restore. The only
difference is that the IP parameters are also reset to their original settings.
Factory default settings - This option resets all parameters, including the IP address, to the
factory settings. Resetting the device to factory settings may be used if you cannot contact
the AXIS 262+, have installed a new hard disk, or if the hard disk LED is red and a restart
does not help.
Note: The recordings on the hard disk will be erased when you use Restore and Default, or set the AXIS 262+ to
factory default settings.
To reset the device to the factory default settings:
1. Press and hold the Factory setup button (rear panel) until the Status Indicator
flashes amber (which may take up to 15 seconds), then release the button.
2. When the Status Indicator displays green (which can take up to 1 minute) the
camera is reset to the factory default settings.
3. Re-install the AXIS 262+ using one of the methods described in the Installation
Guide.
AXIS 262+ Troubleshooting
Upgrading the firmware
Firmware is software that determines the functionality of the AXIS 262+. One of your first
actions when troubleshooting a problem should be to check the currently installed version.
The latest version may contain a correction that fixes your particular problem. The current
firmware version in your AXIS 262+ is shown in the server report, see
> Logs &
Reports.
When you download firmware from the Axis Web site, the AXIS 262+ will receive the
latest available functionality. Always read the upgrade instructions and release notes
available with each new release, before updating the firmware. New firmware can be
downloaded to the AXIS 262+ over the network.
Note: All recorded data and configuration except network settings are erased when upgrading the firmware.
1. Save the firmware file to your computer. The latest version of the AXIS 262+
firmware is available free of charge from the Axis Web site at
www.axis.com/techsup or from your local distributor.
2. Go to
> Maintenance in the video server’s Web pages.
3. In the Upgrade Server section, browse to and select the desired firmware file.
4. Click Upgrade.
Notes:
•Always read the upgrade instructions available with each new release, before updating the firmware.
•Backup all recorded data you wish to save to your PC.
•If you suspect that the procedure has failed, you should wait at least 20 minutes before restarting the AXIS 262+.
•Your dealer reserves the right to charge for any repair attributable to faulty updating by the

34 AXIS 262+ Troubleshooting
NAT traversal
Depending on your network configuration, it may be necessary to use NAT traversal to
access the AXIS 262+ from a WAN. In the example shown below, NAT traversal will
enable the PC located on the WAN to access the camera and the AXIS 262+, which are
located on the LAN.
In the router, port 80 can be mapped to some other port number, e.g. 8080 and port 2000
should be mapped to 2000. When this has been done, the user on the PC can access the
AXIS 262+ by typing the following URL in the browser: http://212.10.10.10:8080
Note: The camera link button may not function in the Main View when using NAT traversal. You can type the IP
address of the camera directly in Internet Explorer along with the port number that port 80 of the camera
is mapped to in the router.

CCD - Charge Coupled Device. CCD is one of the two main
types of image sensors used in digital cameras. When a
picture is taken, the CCD is struck by light coming
through the camera’s lens. Each of the thousands or
millions of tiny pixels that make up the CCD convert this
light into electrons.
CGI - Common Gateway Interface. A set of rules (or a
program) that allows a Web Server to communicate with
other programs.
Client/Server - Describes the network relationship
between two computer programs in which one, the client,
makes a service request from another - the server.
dB (Decibels) - A unit to measure sound level changes. A
3dB change is the smallest level change we can hear. A
3dB change is actually twice or half the audio power
level. A gain of 0dB will leave the signal level unchanged.
DC-Iris - This special type of iris is electrically controlled
by the Axis camera, to automatically regulate the amount
of light allowed to enter.
De-interlacing - An image quality improvement process
taking a stream of interlaced frames and converting it to a
stream of progressive frames.
ETRAX - Axis' own microprocessor.
Firewall - A virtual barrier between a LAN (Local Area
Network) and other networks, e.g. the Internet.
FTP - File Transfer Protocol. Used for the simple transfer
of files to and from an FTP-server.
FPS - Frames per second.
Full duplex - Transmission of data, e.g. audio, in two
directions simultaneously.
G.711 - G.711 is the international standard for encoding
telephone audio on 64 kBit/s channel. It is a pulse code
modulation (PCM) scheme operating at 8 kHz sample rate.
G.726 - Frequently used speech-compression algorithm in
telecommunications due to its high perceived speech
quality and low resource requirements.
HAD - Hole Accumulation Diode. A HAD CCD design
allows for more light to reach the imager, which reduces
video noise to improve signal-to-noise ratio by up to 6dB
(2x better than a standard CCD imager). Particularly
effective when shooting in dark situations.
Half duplex- A half duplex link can communicate in only
one direction, at a time. Two way communication is
possible, but not simultaneously. Walkie-talkies and CB
radios mimic this behavior in that you cannot hear the
other person if you are talking.
HTML - Hypertext Mark-up Language. Used widely for
authoring documents viewed in web browsers.
HTTP - Hypertext Transfer Protocol. The set of rules for
exchanging files (text, images, sound, video, and other
files) on the World Wide Web.
Intranet - A private network limited to an organization or
corporation. Usually closed to external traffic.
IP - Internet-Protocol. See TCP/IP.
IP address - A unique number used by a network device,
to allow it to be identified and found on the network. The
32-bit IP address is made up of four groups (or quads) of
decimal digits separated by periods. An example of an IP
address is: 192.168.0.1
ISMA - Internet Streaming Media Alliance
JPEG - A standard image format, used widely for
photographs. Also known as JPG.
LAN - A local area network (LAN) is a group of computers
and associated devices that typically share common
resources within a limited geographical area.
Linux - A popular operating system, which is “open
source” and practically free of charge.
DNS - The Domain Name System (DNS) locates and
translates Internet domain names into IP (Internet
Protocol) addresses.
Lux - A standard unit for the measurement of light, where
1 Lux equals the light emitted from a single candle at a
distance of one meter.
Ethernet - A widely used networking standard.
Mbit/s - Megabits per second. A unit for measuring
39

speeds in networks. A LAN might run at 10 or 100 Mbit/s.
MPEG-4 - A standard video format, used for low
bandwidth video streams.
Multicast - The same information is sent only once and
only to the intended recipients.
NAT - Network Address Translation is a standard used to
allow multiple PCs on a private network to share a single,
globally routable IP address.
NTSC - National Television Standards Committee. NTSC is
the standard format used for televisions in most of North
and Central America, and Japan.
NTP - Network Time Protocol. Protocol designed to
synchronize the clocks of computers over a network.
NWAY - A network protocol that automatically
negotiates the highest possible common transmission
speed between two devices.
PAL - Phase Altering Line. PAL is the standard format
used for televisions in most of the world (other than the
US, Canada, and Japan).
PCM - Pulse Code Modulation. Analog signal converted
directly to a digital.
Ping - A small utility used for sending data packets to
network resources to check that they are working and that
the network is intact.
Pre/post alarm image - The images from immediately
before and after an alarm.
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.
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 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 direction.
SMTP - Simple Mail Transfer Protocol is the protocol used
to send e-mail across the Internet. SMTP authentication is
a way of allowing people outside of a domain to use an
SMTP server when sending e-mail.
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
network.
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).
