It’s especially important that it works at night. Cost is not a factor, ease of installation is not a factor. Preferably hard wired. We have our own instrument/electrician techs who are wizards at running wires and getting things running.

We currently have a single PTZ camera on our office building overlooking the parking lot, it’s uses coaxe and it sucks, the picture is useless even in daylight. It’s mounted on a pole on the roof (flat roof will a small wall around the perimeter). New cameras will also have to go on the roof. I don’t really care about PTZ, two or three cameras would probably be better since they wouldn’t pan away and miss something. I don’t think we have receptacles up there but it’s not impossible, is this a good situation for PoE? Current wire run is probably 100′ to the DVR.
