I finally got my Zoneminder system up and running. Seems to work fine, but it was a lot of hassle. If anyone else goes this route and are bringing in analog feeds be sure to research the capabilities of the video adapter. The one I purchased only has one BT 878 chip on it, but 4 inputs so if you want to watch more than a single camera at a time it divides the bandwidth and I ended up having a lot of video artifacts. I believe there are higher end cards that have one chip per input so that you can get full bandwidth on each input.
