sameerali78 0 Posted November 9, 2012 Have any of you guys ever had a video interference problem when using video baluns and a multi-channel pwer box over CAT 5? If we to use individual power adapters instead of the power box, the problem goes away. Is it a grounding problem of some sort? Share this post Link to post Share on other sites
DWCCTV 0 Posted November 10, 2012 Hello, Try using a Ground Loop Isolator. These have saved the day for me on many occasions. I am typically using these on buildings with electric done 10+ years ago. George Boyle Dallas Wholesale CCTV Share this post Link to post Share on other sites
GrouchoBoucho 0 Posted November 12, 2012 this is definitely a ground loop problem, and it's caused by the cameras having a common video and power ground. quality cameras with built-in regulators avoid this problem, as do dual-voltage and ac-powered cameras. there's a good description of the issue here: viewtopic.php?f=15&t=23788&p=142487p142487 Share this post Link to post Share on other sites
