    I am making a video system where I can control the camcorder down a 100 ft line.
    I have a 100 ft S-video, rca video and power cable running a pan/tile head which works fine, but I have created adapters to extend the 1.7mm X 4.75mm plug/jack to a standard 2.1mm X 5.5mm CCTV camera power connector so I can use the standard cable.
    I have also wired the two remotes to RJ 45 jacks and can run them through 100 ft cat5 cables.
    If I connect the adapters without the 100 ft cord it works, so I know my adapters are wired properly.
    The pan/tilt head has a 12 volt regulated power supply, not sure the full meaning of that.
    So what would be my solution to getting the power to the camcorder?

    Send 12v dc down the power cables, or use a local psu at the camera end.

    Or send 18vdc (number picked somewhat at random) and locally regulate it to 12vdc.
