s0da9 0 Posted May 17, 2014 Hi, We have used CAT 5 UTP cable for our CCTV cameras, but instead of placing video baluns, we directly connected it to a male BNC connector no both sides, now when we connected it to the DVR the video output seems to be grounded. is it the cable or should we use a video balun?
