Looks nice.  There is a similar thing available (though probably less
sophisticated) from http://www.atmltd.co.uk/ms32bspp.html
which might be
worth a look.  I don't think it has motion detection software, but I know
one place where it is being used, switching with PIRs.

The software I'm using is motion for linux.  There's source available at
http://motion.technolust.cx, if
you fancy trying to port it to
Windows!  Another neat feature on it is that the motion masking is defined
by a colour 'overlay' (other programs just let you define rectangles of
'sensitive areas'), so you can have varying sensitivity on each pixel, for
intensity and even colour of the movement image!

At the moment, I just have it masking off a main road in the corner of the
picture, with a simple black and white overlay.  Only snag is that I can't
switch the overlay when I change cameras without getting in to the source
to change the code and get Comfort to tell it which camera it is
viewing.  It's not really a big issue, so I'll probably just live with it!
