    Possibly.
    CCTV, will normally be composite video, at 60Hz 'interlaced'. Now _some_
    older computer monitors may (just) be able to work down to this sync rate.
    On these all that would be needed, would be a composite to RGB decoder.
    However most monitors will not go down to this low a sync rate, and then
    at the minimum, a 'frame store' will be needed to generate an output
    picture at double the line rate coming from the camera. Such units are
    called 'scan converters', and are relatively complex.

    And, this is far less, than you'd even be able to 'part build' such a
    system for...
