Video Servers
AXIS 241 Video Servers from the market leader in network
video, are designed to migrate your analog investments into
high-performance IP solutions, ideal for surveillance and
remote monitoring.
The AXIS 241 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.
AXIS 241QA/SA 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. In addition, they offer a
de-interlace filter that improves image quality in the highest
resolution (4CIF).
