Technical Details for the Axis 241 Video Server

System Overview

The AXIS 241 Video Servers help you migrate your existing CCTV system into the digital world. One unit can network up to 4 analog cameras – a cost-effective solution for transmitting high-quality digital video over computer networks. Bridging the analog-digital technology gap, the AXIS 241 complements any previous investments in analog cameras and avoids extended problems with complex coaxial cabling. Axis 241 Video Server The video servers accommodate one or four analog video streams, depending on the model. System integration and network utilization are optimized with sophisticated functions such as built-in motion detection, SNMP and simultaneous Motion JPEG and MPEG-4 streams. Powerful event management tools include image upload, alarm notification and I/O control. Pan/tilt/zoom control is done over the serial port, enabling PTZ and dome camera handling over the network. A complete set of security features, including multiple user access levels, HTTPS encryption and IP address filtering, ensure secure video handling and configuration. The AXIS 241 Video Servers offer a de-interlace filter that eliminates interlace artifacts from NTSC/PAL cameras. In addition, the AXIS 241QA/SA models provide one audio stream in each direction, enabling users to not only see, but also listen in on an area and communicate requests or orders. For surveillance installations that require many AXIS 241Q/S, blade versions of the video servers are available for use with the AXIS Rack Solution. Specifications
