Kmorris 0 Posted January 7, 2009 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! Share this post Link to post Share on other sites
scorpion 0 Posted January 8, 2009 You have a system that shares common ground. The shield of the coax is the ground, and the white is the center conductor of the coax. Red is positive, and the negative is the same ground. The butt connection should work. The only draw back would be the kind of coax you use. Do not use CATV cable for cable/sat. They use a steel center conductor that copper coated. CCTV is low freq, and cable / sat is high freq. Low freq travel in the center of the wire which needs copper center conductor, and high freq travels on the outside of the center conductor which is why they can use copper coated. If you butt connected to copper coated coax, then movement may cause the butt connector to "scrape" the copper coating off the steel center conductor creating a bad circuit, or no signal at all. You might try soldering to the center conductor if there is movement of the wire is anticipated. Share this post Link to post Share on other sites
