I've got a GV800 7.4 working in neighborhood bar I own and someone gave me a pelco spectra II b/w PTZ camera and I would like to know if this would work with the Geo800 card and what additional hardware I need to get it up and running,thanks

That camera should work fine. You will need a GV NET card to communicate with the camera, and some 2 core cable running to the camera for telemetry.

The GV NET card will require a free COM port on your GeoVision computer.

or you can use the GV-COM and communicate through a USB port
