redisol 0 Posted June 15, 2007 Hi! I just finished installing 3 cameras to my new avtech 760 dvr in my home and noticed that the video from one of the cam is very noisy w/ lots of interference patterns. I managed to trace the source to the catv signal which is connected to the same tv set I'm using as a monitor. The noise disappears whenever I disconnect the cable from the dvr to tv set or when I disconnect the catv cable. Is there any way to fix this? I tried replacing the cable and connector from the DVR to the TV set and the noise is still there. Thanks Share this post Link to post Share on other sites
VST_Man 1 Posted June 15, 2007 obviously the noise is being inducted via the cable/tv..........you can try to use a ground loop isolator or grounding all of the equipment to one ground. if it is GL you can block it. if it is a noise issue with the cable signal you can't. need to find the source and stop it.call the cable guy? most likely he won't have a clue as to how to isolate that noise? but it maybe worth the call another trick is to use CAT5 with baluns with GL noise isolation between the DVR & tv?
