Best IP based video surveillance camera (and housing) with day/night,
all weather capability. I live in Alaska and need usability down to
minus 20 F or minus 30 C. Best for me means that it will work in my
environment at the lowest cost. I am looking for a PTZ color version
(dome) as well as a fixed focus black and white. The color cameras
typically switch to black and white in low light and may require IR
illumination for best results. Products like the Axis 232D are nice
but the housings available only go to -20 C.

There's another way to solve the problem of outdoor video surveillance
in cold temperatures. The answer is to use ultra low bandwidth,
outdoor Multi-Stream Video Servers made by Boundless Security Systems,
Inc., (www.BoundlessS.com) combined with outdoor CCTV cameras. Not
just a video-encoding server, each Multi-Stream Video Server handles
four CCTV cameras and provides internal recording as well as motion
searching of recorded video. Four live and/or recorded video streams
can be sent simultaneously over a long-range Wi-Fi wireless link with
a total bandwidth for all four cameras of only 128 Kbps, with 5 frames
per second per camera.
