I would have done IP, but I have severely 600' runs that have to place for repeaters.

Hello everybody! I've been an AV installer for years, but this is my first camera project. I opted to go with TVI and Siamese. Here are my components... 4 Domes - KT&C KEZ-C2DR28V12IRN - 12/24V 4 Bullets w/ 160' IR's - KT&C KEZ-C2BR12XIR - 12/24V Hunt 32 Channel 8TB DVR WattBox 18 Output Rack Mount Power Supply - 12VDC - 20A - PTC Fuses Issue number 1: One of the domes is not giving any picture, even when hooking the camera straight to the monitor port. I decided that I'd try a 2nd camera and still having the same issue. I can hear a clicking inside, almost sounds like a shutter opening and closing, but that's it. I'm getting 16.3VDC at the pigtail and when hooked up I'm getting the same onto the board in the camera. Admittedly I haven't checked the voltage on any of the other cameras but I have tried different outputs on the power supply. Issue number 2: On 2 of the 4 bullet cameras they seem to be turning themself off over night, I can only assume this has something to do with the IR's kicking on at night, because I can reset them the next day and they work great, next morning they will be off again. I realize these are total newby problems, but I'm desperately trying to get this job wrapped up and learn from my mistakes. Any help at all would be appreciated!

I'm going to look at them now, but to clarify that if I switch to a 24VAC power supply I don't have to make any changed to the power end of the camera? Thanks, Mark

Not to question, just curious... But even if they are dual voltage cameras?

They are definitely all TVI and the DVR is TVI as well. I was checking them using my monitor, but I was using the included pigtail that allows it to be viewed using the nonTVI standard. I have more camera working than not working and I only have 2 different models of camera. I agree with you on the Power Supply. I checked an output on the power supply and I'm getting a little over 17vdc. I called WattBox and this appears to be out of spec so they are sending a replacement. So that's a start. Follow up questions.... They have all been running like this for a couple weeks, should I go disconnect them all until I get the new power supply or just let them run on over voltage? I think I'll go research a 24v power supply, that won't change anything on my camera end will it? I can just replace the power supply and be up and running? Thanks again! Some great knowledge here!
