    So, I'm new to this forum, and I hope I'm posting this in generally the right place. If I'm not, could you please point me in the right direction if theres any place you know of online where I could find an answer. Thanks. Anyways:

    Now I don't think that the hardware specs are important regarding this specific problem (and honestly I forget what the specs are for the camera), but if you think its necessary I can find out.

    These cameras (there are 2 of them) are currently mounted on the outside of my home's front wall. The wires are run through into a closet directly adjacent to that wall, where they are hooked into a DVR system. I have tested the power connection for both cameras successfully, but when I hook in the data line to the DVR, I end up with a picture like this:

    Any ideas why the picture isn't even showing up?

    Hi, and welcome to TSG.

    If the two camera's outputs are in the two top left boxes in the displayed grid, are they aimed so that that are viewing a sunny or brightly lit area, behind a fairly dark area? If so, the cameras don't have enough dynamic brightness and contrast range to capture the whole scene. Do the cameras have any way of adjusting their aperture setting for different lighting conditions?

    Edit: I am going to ask a moderator to move this to our DIY forum.
