Great site! First time on. I have a Watec WAT-704R monochrome covert camera which needs powered by a 9v power source which is no problem. However, the camera has three wires (cat5 size) coming out of it. Red for power - white for video out - and a ground wire. How would you hook this up to a power souce that has 2 wires for hot and cold? Also, would the white wire just be butt connected with a coax? I have never seen a connection quite like this. Please help!
