a3dm 0 Posted October 15, 2015 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. Share this post Link to post Share on other sites
topchips 0 Posted October 23, 2015 Hi Try running a separate PSU just for that cam and see if you get the same result, also ground your DVR at the back there should be a ground screw, also what is the camera mounted on and what cable you using? also try removing the negative on the power connection for the camera let the video be the negative for the cam that sometimes works hope this helps Regards Share this post Link to post Share on other sites
