Product description

This manual describes the AXIS 241QA: 4-port video server including 2-way audio, and

the AXIS 241SA: 1-port video server including 2-way audio.

Overview of the AXIS video server

The Axis video server is fully featured for security surveillance and remote monitoring needs. It is based on the AXIS ARTPEC-2 compression chip, and can digitize up to four analog video sources and make these available on the network as real-time, full frame rate Motion JPEG and/or MPEG-4 video streams.

The Axis video server is equipped with RS-232 and RS-485 ports for connecting third party PTZ systems. The 4 alarm inputs and four alarm outputs can be used to connect various third party devices, such as door sensors and alarm bells.

Up to 20 viewers can access the Axis video server simultaneously when using Motion JPEG and MPEG-4 unicast. The number of simultaneous viewers can be increased by using multicast MPEG-4. When using AXIS Media Control (AMC) to view MPEG-4 video streams, each MPEG-4 viewer requires a separate MPEG-4 decoder license. One license is included, and further 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 five resolutions (up to 4CIF), and image compression is configurable. The Axis video server 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 video server 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 video server has a built-in web server, providing full access to all features through the use of a web 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 VAPIX® Axis Communications’ powerful API (see www.axis.com/developer for further information).
