AXIS 282/282A - Product Description
Product Description
This manual is applicable for the following Axis Video Servers:
• AXIS 282: 1-port bare board video server
• AXIS 282A: 1-port bare board video server, including 2-way audio
The information provided in this manual applies to both models, unless otherwise
indicated.
The AXIS 282/282A is a small form factor video server board designed to be built into
domes, fixed view cameras, PTZs, analog devices, etc., and is fully featured for security
surveillance and remote monitoring needs. The AXIS 282/282A is based on the AXIS
ETRAX 100LX network optimized system-on-a-chip (SOC), and the AXIS ARTPEC-2
compression chip. The AXIS 282/282A can digitize one analog video source and make it
available on the network as real-time, full frame rate Motion JPEG and/or MPEG-4 video
streams.
The AXIS 282/282A is equipped with RS-232 or RS-485 ports for connecting third party
PTZ systems. It also has 1 alarm input and 1 alarm output, which can be used to connect
various third party devices, e.g., door sensors and alarm bells.
The AXIS 282A has a Line/Mic In (mono), via the internal connector I/O pins, for
connecting an external microphone or other source producing a line level signal. An active
speaker with a built-in amplifier can be connected to Line Out (mono) to enable two-way
communication. Audio communication can be bi-directional (full-duplex), push to talk
(half-duplex) or in one direction only (simplex).
Up to 20 viewers can access the AXIS 282/282A simultaneously when using Motion JPEG
and MPEG-4 unicast. Each MPEG-4 viewer requires a separate MPEG-4 decoder license, of
which one is included. Additional licenses can be purchased separately from your Axis
dealer. If using other clients to view the MPEG-4 video stream, no further MPEG-4 decoder
licenses are required.
Video can be viewed in 5 resolutions (up to 4CIF), and image compression is configurable.
The AXIS 282/282A contains support for video motion detection, which allows the unit to
trigger on activity in the video image, and advanced scheduling tools which can also be
used to trigger an event. As the AXIS 282/282A is designed for use in security systems, it
is equipped with several security features, such as IP address filtering, several user levels
with passwords and HTTPS.
The AXIS 282/282A has a built-in web server, providing full access to all features through
the use of a standard browser. The built-in scripting tool allows basic applications to be
created, providing basic surveillance solutions. For advanced functionality, the Video
Server can be integrated via the use of the AXIS HTTP API (see www.axis.com/developer).
