I think that video would be preferable unless there were a large number of
stills taken per minute.  I would certainly hate to miss some action becuase
it happened between frames.  You are right though that a still picture can
have a much higher resolution that a single frame from a video feed.  Maybe
one decent sill per second would be better than 30 FPS video, I don't know.

When I was talking about using a PC, I would referring to a current
generation PC loaded with a large hard drive, a gig of RAM and plenty of
excess processor time running a stable version of XP - that is to say, as
stable as Microsoft is able to get it!  A high speed Internet hookup opens
up the opportunity to back up any images remotely, further increasing
security. The truth is, every decision in life comes down to tradeoffs in
one way or another.  Yes,  the PC might not be as reliable as a dedicated
DVR server but if dollars prohibit purchasing a DVR for home use, perhaps a
PC that is already sitting there in the office, doing nothing much of the
time is a cost effective alternative.  If it is up 80% of the time, you're
still better off than not having any system.

Thanks for your input.
