robfet 0 Posted June 9, 2011 Hi there, Im not an expert at CCVT but in my job im the responsible for any problem with the CCVT. So, I have a camera that is not working good. For while the camera looks great, good image, but after a while the image turns to black and kind of blur. I changed the BNC connector at both sides but its making that problem too. I change the camera for anohter at that spot but its the same, so I thought It could be the light contact so I checked the voltage and is at 122V, it doesnt have earth the contact, could this be a problem? or should I cable back?

Aban-CCTV-Camera 0 Posted June 16, 2011 Have you tried connecting a new/different camera direct to the back of the DVR on a small length of fresh cable? Share this post Link to post Share on other sites
robfet 0 Posted June 16, 2011 No. this for see if its the input of the DVR? If this correct, I switch with other input and its the same problem. Also, I use a surge protection on the camera but it the same results. I guess I'm going to cable back again!! any more ideas? Share this post Link to post Share on other sites

I dont really understand your problem but you can check the coax cable if it is shorted or broken. Get a VOM and check for continuity or short. Maybe you are having ground loop problem.
