Bob,
As you know, the cam is the Canon VB-C50iR (reverse, it mounts upside-down). The cam itself is an indoor rig and needs an heated/cooled housing if located outdoors. Seems most of the places that sell the cam also sell the housing. I got mine from
http://www.nuspectra.com, they have a picture of both the cam and housing on their home page. The housing has a blower and heater for -20, and takes a 24v AC power lead. It has a bui9lt-in circuit to convert the 24vAC to 12v DC for the camera. I ran just a single CAT5 cable using 4 wires for the Ethernet and two others for the 24V. It is a bit pricey (OK, its actually shamefully pricey!), but I couldn't resist.
Unfortunately, the very day I put it up, my T1 Internet feed started taking CRC and frame errors, and we're are working on it today.
