    Uh, yeah, I'm starting a museum too. I need a 16 channel DVR, at least 120
    fps with a 320GB HDD.

    If you know how to solder, you can make your self a 2 to 10 cam
    sequential video switcher cheap. The below site shows how I made
    one using a 4017B decade counting chip from Radio Shack. Radio
    shack doesn't carry the chip in the stores now, but you can get
    an LED chaser kit from Allelectronics that has most of the parts
    needed for $6.50 (bottom link). You can have timed switching,
    manual switching, event switching, and web controlled switching.
    Cheap project for the DIY types.

    I need to update the page a little, as the optical isolator isn't
    really needed for the computer control, and I think the bottom
    switch in the schematic can be replaced with 2 diodes in series.
    I'm looking at another project to work into this for a simple and
    cheap cam pan/tilt setup using RC servos to pan/tilt small cams.
    I already do the pan/tilt via a computer with a webcam, but this
    wouldn't need a computer, and the cams pan/tilt would be
    controlled with a simple joystick. A cam would be selected via
    the switcher, and then the cam positioned as desired using the
    joystick. Probably less than $70 for first switcher/pan/tilt
    unit, and ~$40 for each additional pan/tilt unit.
