RiazK 0 Posted August 19, 2015 First post here . I would like to view my cctv dvr on the tv's around the house. As instructed, I got a BNC to RCA adaptor and made a cable. I connected the cable from the DVR's BNC VIDEO OUT to the TV monitors RCA. It worked fine, for a while only. After a few minutes it became very very hot to touch so I disconnected it. I reconnected a new cable and it was fine. 2 Weeks later the connector became hot again and got damaged (it melted the white plastic inside). I'm not sure what the problem is, I tried 2 different tv's, and 2 different cables. They heating only occurs at the connectors, not along the length of the cable. Can anybody tell me what I am doing wrong ? Share this post Link to post Share on other sites
the toss 0 Posted August 19, 2015 As long as you have done as you describe there should be no issue. You say you connected to the TV's RCA. I assume it WAS the TVs "VIDEO IN". The signal is only 1Vpp @ negligable current and so is incapable of generating heat. I cannot offer any other help on your problem Share this post Link to post Share on other sites
RiazK 0 Posted August 19, 2015 Yes, sorry, I did mean "Video In". I made 2 cables. The second is only about 1m in length, only to test. I have tried to attached an image to describe what happened to the cable. I'm not sure what could possibly be causing this. Share this post Link to post Share on other sites
RiazK 0 Posted August 20, 2015 How can I test if there is a problem with the BNC Video out connection on my DVR? Should there be continuity between the centre pin and the outside of the connector? Share this post Link to post Share on other sites
Squirrel! 0 Posted September 7, 2015 Possibly a bad BNC to RCA adaptor. Get a volt meter and see what kind (if any) voltage is being output. I have no other ideas at the moment. Share this post Link to post Share on other sites
