I've been working on a camera/VMS solution for my jail for months now. This solution involves investing heavily in the VMS so we have the features everyone wants, and using cheap cameras to save on the bottom line.
I have a local vendor that sells me 4MP Uniview Tec cameras for $78 each, when I buy 50+. I like these cameras because of the combination of price, metal housing, small size, and relatively good quality for the price. The plan was to use these cameras with an integrator-installed Exacq server, running 128 cameras.
Well, I got a small exacq server on demo and hooked one of the Uniview Tec cameras to it. It recognizes the camera as Onvif and says motion detection is unavailable for this camera. Doh! I had figured since Exacq works with a lot of Uniview models, the American rebadges would be the same. I guess I was wrong.
It's my understanding that a VMS really needs the camera to provide motion detection, otherwise it will kill my server with the processing power required to do so. Is this true? If so, can you recommend a low cost solution that may be comparable to the cameras I've found, but also support motion? We house federal inmates, so I'm trying to avoid Dahua/Hikvision, just in case that would affect our funding.
