Axis 247S Video Server (Analog to Digital)

I recently installed a pair of Axis 247S video servers with a pair of Topica TP-6360WBC-DN analog cameras attached to a ZoneMinder video server at one of our VSS(1) client sites. For those of you looking for quick information – the Axis 247S works great with ZoneMinder. One can use the Axis presets for their network cameras when setting up the monitors in ZoneMinder.

Now for the details.

The physical install included running LAN backbone cable to the punchdown block near the 8-port Linksys POE(2) switch as well as to jacks near where the cameras were to be installed. Four 3′ patch cables were used, two at the switch <-> punchdown block and one at each jack <-> 247S. The cameras were ordered with 25′ of Video / Power extension cable to connect to the Axis 247S video servers on the analog side. Also a pair of pigtails were ordered to power the cameras using the Axis 247S power connector. This is a sweet solution for powering the cameras as it avoids having to use the wall warts that come with the cameras. Also the whole thing is powered using POE meaning the power is also provided through a battery backup to keep the entire system up during short power outages or brown-out conditions.

Each Axis 247S was connected singly (as they all default to 192.168.0.90) and configured using the Firefox web browser off the VSS while running X with fluxbox on the VSS. Since the camera LAN segment on a 192.168.0.* subnet is separated from the end-user’s other LAN segment on a 10.10.10.* subnet this is the simplest way I know to configure them for use with the ZoneMinder server (especially since I forgot to take my laptop with me). The ZoneMinder server is configured like all our ZoneMinder servers with two gigabit ethernet network connections. One goes to the POE gigabit switch powering the cameras and the other connects to the client’s existing LAN. This keeps the bandwidth needed for the cameras off the client’s LAN. Once each Axis 247S was configured using its’ internal web interface it was added to the ZoneMinder server as a monitor using motion detection (modect). A tweak on each to lengthen the recording sequence so as to avoid the ext3 filesystem problem with 32000 directories (these folks keep 90 days of video and each event gets its’ own directory!) and the system was working great.

For the record, our next ZoneMinder VSS will be using XFS for the filesystem so as to avoid the problem with ext3 and 32000 directories.
