I have had a system installed at a warehouse for a year and a new problen has arisen:
The video of one camera is completed distorted. (See attached photo.) It only happens at certain times of the day. I have taken the following measures to try and solve the problem to no avail:
1. Replace DVR
2. Run a new RG59+pwr cable (no closer than 5ft from any high voltage lighting or conduit.)
3. Replace the camera
4. Replace the power supply
5. Install a Pelco GIT100 Ground Loop Isolator near the DVR
6. Grounded the equipment rack
7. Every component is plugged into the same AC outlet via an UPS.
I STILL HAVE THE SAME VIDEO DISTORTION!!!
Is it possible that the brick wall the camera is mounted to has somehow induced a ground loop strong enough to over power to GIT100??
I have spent days of work and come up with no solution. Please help anyone if you can.
