I appreciate everyone's input. The camera had the following information, which I cant seem to find the exact model, but I just need something that will work:
MFG By PELCO, CLOVIS, CA, USA
Model: DDTAC
freq: 60 hz
Watts: 17
Volts: 24vac
ref: 4.63
The software used is ADVENT - and the some of the cameras feed into a rack mount device that didn't have any markings other than on the back it had the following Ports: LAN, COM, SW1, and in and out BNC connectors.
I have photos to show but cant get them loaded. I am embarrassed to say that I am in over my head a little on this one. Thanks,
