carcol_123 0 Posted May 28, 2014 I am no expert, but I had interference and I fitted BNC ground loop isolators to all my cameras(3), did not solve the problem, so i posted a blog on this site. The answer to my problem was using a cheap mains transformer (you know the one all built in the 13 amp plug top), I replaced it with a separate trans former 12 volt DC and it solved my problems. I get lovely pictures now with no interference, hopefully this is your problem Share this post Link to post Share on other sites
epcjay 0 Posted June 2, 2014 I ordered some bad quality power supplies that caused the problem too. Switched to something else and its a lot better now Share this post Link to post Share on other sites
fplenin 0 Posted June 3, 2014 Is it on a single camera? If other cameras on same lenght cables are running fine, you should try switching power supply to see if there's an improvement or not. What's the lenght of the cable? Are you using the same power phase? I've readen that if you use different phase to power CCTV cameras you could also get interference.
