CCTV camera has three wires Red, Black and Yellow. I have connected the red to positive of power supply and black to the gnd of power supply. The yellow to composite middle and the gnd of power supply to the outer ring of the composite RCA connecter. Are the connections ok??? All I am getting is a black screen. The camera is working fine as indicated by a LED. Any suggestions?

While installing a CCTV i just connected red to gnd and black to positive of the power supply and turned it on. Now after realizing the mistake I reconnected them correctly. Now there is no video output. Is the camera damaged??? If, yes is there any thing that can be done to repair it???

ok got it working..........thnks a lot ...............

so that means the negative of DC out from the adapter will be acting as ground and is combined with the yellow(VIDEO OUT)???

I have a CCD PCB it has three wires RED, BLACK AND YELLOW. I figured out that Red was positive and Black was gnd...and hav connected them to the power supply. The camera powers up indicated by a LED. The question is how do I get the video to the TV? is it possible to connect single yellow wire to the ANT IN or VIDEO IN?? if so how?
