I use Zoneminder with two wireless CCTVs. You can get a cheap bt878
codec card ~£15 (Multimedia controller: Brooktree Corporation Bt878
Audio Capture) and the scart in/out conversion box from ebay. ZM motion
detection is superb and together with its filters can reduce the disk
usage to a minimum.
I normally compile zoneminder from source but have just found that
Fedora 7 yum repos have it now. My problem is the cheap cards work well
but the image quality is poor and I can't find a better quality card
that runs on Linux (I did get a 100fps from China ~£50 but it completely
locks up the pc after several minutes running ZM).
