BNC/RCA adapters are available cheap at any electronics supply (Radio
Shack, etc.), if necessary.
One thing to remember too is that recording video _can_ take up a lot of
disk space and CPU cycles. If you want something as a constant
surveillance recorder, especially if using more than one camera, you
might want to consider a dedicated computer for it, and probably have a
dedicated hard drive for video storage. 80GB drives are dirt-cheap
these days and should hold a good bit of video, depending on various
record settings (constant vs. motion record, resolution, frame rate,
compression level, etc.)
