[H] Using a webcam for security

[Thane Sherrington]

I have a customer who works for a Salvation Army Centre who wants to 
setup an old PC with a webcam and record the front of their building 
where they are having a problem with vandalism.  He wants to record 
the video (or stills taken every second or two) to the hard drive but 
only when there's motion outside.  He also wants to be able to login 
over the net and see what the webcam is recording currently at any 
time.  Anyone ever set anything like this up and have suggestions?
