shawn6542 0 Posted October 27, 2016 I have a 4 camera CCTV system with a DVR all cameras are connected with cat5 to the DVR the problem is that on all the cameras there are vertical rolling rainbow lines. I have tried to keep the cables as far away from power lines as I can but the lines do not go away each run is around 40 feet I have heard that if you use cat5 you need to use baluns do you think they would fix the problem? Thanks for your help Share this post Link to post Share on other sites
