I installed this little system for a client and one camera gives me a black fuzzy image. I put a ground loop adapter and it went away. However it came back a couple of hours later (adapter still installed). I removed the adapter and miraculously the camera worked great. Again, only for a couple of hours then the same thing happened again. I plug in a test monitor on the camera and it works fine. It's just when it's plugged into the Dvr. It's any camera plugged into that specific cable. What could be wrong? It's brand a brand new cable run.
