I've swapped working cams into that port and got a picture, so that rules out the port. Now, i'm at the point that i believe the camera isnt recieving enough power to be able to send the signal back to the dvr? I'm also having issues with a 24v AC power supply( that works fine with one camera attached. If i add another camera to the power supply i get lines and distortion in both pictures. any thoughts? i thought maybe the wall outlet wasnt supplying both of my power boxes w/ enough juice.

its a dell gx620 with a video insight vj60 card.

These are all good things that I will try tomorrow morning and let you know what my results are. Thanks for the help and I will post my results as soon as possible.

I have replaced the camera 3 times and I still have the same result. I am powering the camera with an Altronix 6-15V system. It is fused on each channel. I am keeping the camera constantly powered this way. So I do believe polarity is correct and we have checked the fuses. We are reading correct voltage with our multimeter at the camera end and DVR end. I will hook up the LCD locally to the camera leaving it powered by the Altronix system and receive display. but I will not receive the display on the DVR or when I hook up the LCD on the DVR end. **I have not tried putting the DVR Video out on the same cable and trying to pick it up with the LCD. I am going to try that tomorrow morning to rule out cable, but unfortunately, we broke our STP cable tester and haven't gotten around to replacing it...we need to.

I have tried 3 different cameras and this nothing. When I hook up the LCD at the DVR end I do not get any picture there either.

I have hooked up the LCD at the other end to test the entire cable and it doesn't show there either. I have done this after running 3 different cables.

I have a 12V DC camera in an outdoor housing and I am unable to see any video at the DVR unit itself. When I hook up a local LCD screen to position the Camera everything is fine and I am using the siamese cable to power the camera when using the LCD and not the local battery on the LCD unit. We have replaced the siamese cable 3 times and have recrimped the ends multiple times (the cable run is probably about 30 ft). I was hoping someone would have a suggestion as to why it works when the LCD is hooked up but will not display at the DVR unit itself. Other cameras are hooked up the the DVR and they work fine, but this one 12V DC does not. We have tried using different video channels on the DVR, different power supplies, but nothing is working. We are using an Altronix power distribution box and we have tried different outputs on that as well. If someone could just point us in the right direction to isolate the problem I would really appreciate it.
