Security camera too bright

    I have a security camera that plugs into the AV jacks of my TV. The
    picture is much brighter (blown whites) than when I watch off air
    broadcasts. If I turn down the brightness the camera looks ok but then
    everything else is dark. If I connect a potentiometer to the video
    line and connect the wiper to the TV would that change the brightness?

  3. Along with the sync signal which can cause the monitor not to lock
    onto the source. Is the video input terminated at 75 ohms? Some are
    high impedance to loop multiple monitors and require an external 75 ohm
    terminator. A few have a switchable 75 Ohm termination.

    I think you should change that camera with another camera. See if the problem moves to the new location. If yes, then camera is the problem. If no, then maybe settings or wiring is the problem of your security camera. Good luck!
