bicylindrico 0 Posted January 19, 2013 I have been lurking for some time and picked up a couple of items in hopes of making our home a little safer. We are not wealthy so I started by just picking up a DVR and a dome camera to put out at our gate. The 2 items I selected are a Dahua DH-DVR0804LE-AS DVR and a CNB LDM-20S camera. When I installed my pillars for my gates some time back I also ran some RG6 quad with hopes of doing something with it in the future. This is a 400 foot run. I decided to try and use this for the security camera and installed BNC connectors on the cable. The camera is 12vDC and I have a couple of 12vDC outputs on my automatic garage door opener to use for powering the camera. I checked them and have 12.05 volts. I think you know where this is heading. I can't get it to work. The DVR seems to be doing just fine. I installed a 1TB WD Caviar hard drive and everything seems to work fine on my screen. Just no video. I tried running just a one foot coax here in the living room and still no video. I tried hooking into the coax input of my TV and still no luck. I noticed the camera came with an RCA video jack on a pigtail that could be plugged into the board of the camera so I tried it into one of the video inputs on my TV and still no video. The small setup guide that came with the camera states that the camera has a UTP transmitter already installed and it shows UTP connections for installation. Is this where I am going wrong? There is no power LED or anything for me to know it is powering up. Should I be able to read a voltage from the video output? Is there any way to know that this camera works? Thanks for any help you can provide Share this post Link to post Share on other sites
yakky 0 Posted January 19, 2013 I believe the UTP thing is a misprint, regardless you should still get something on the screen. I'd recommend picking up a powersupply from amazon, they are $6 for the videosecu brand for CCTV cameras. It is possible you have a bad camera. Share this post Link to post Share on other sites
greenturtle 0 Posted January 23, 2013 We just installed our Vcm-24vf camera today and also had 'video loss'. DVR was working fine and power was good at both source and camera. Turns out we didn't properly connect the BNC connectors to the RG6. We didn't push the coax in far enough before compress crimping the BNC. Once we re-did that, video was on. Your situation sounded similar... Share this post Link to post Share on other sites

If not then it's not getting power. Test continuity of your 1 foot coax pin to pin and outer to outer as well as no short circuit from outer to pin. If this is ok & you're sure there is power at the camera then the camera is scrap. Share this post Link to post Share on other sites
