I work for a large sporting goods retailer. In this specific store I have/had 2 PTZ cameras working with my Clinton DVR. Just a week ago both cameras were working fine until one of them stopped. I took it down and unplugged my working one to see if the broken one would work in that spot. Nothing. I plugged my good one back in and now its not working. No picture. No movement. All i'm getting is a red/green blinking light when I look strait up at it from the floor. Its an old analog sensormatic PTZ camera. Does anyone know what the red/green lights mean? I've tried everything. I even called Sensormatic but they were clueless.
