    Hi all

    Quick one parents have a cheap 4 camera system probably 7-8years old at this stage.

    On the image overview there looks to be a wave like interference on all the images.

    Any idea what it could be thanks

    And is that still there if you view each single camera on a full screen?

    And if you disconnect the camera inputs is it still there.

    Not at the parents house at the moment i disconnected one input earlier and when i did the screen went black but was perfect no image distortion on that input but remained on the 3 remaining inputs

    The set up is four cameras all connected via bnc and power cables ran and connected in junction boxes outside.

    Whoever they got to install the system it just split the 12v via a 6way splitter at the back of the dvr, there is no rating on the transformer no markings at all.

    i think the cameras used only use 500ma when the infra red is activated

    Thanks again for the replies koolkid:)

    Sounds like it may be from the cameras themselves. Are they all on the one power supply?

    More than likely it's the power supply failing.
