These guys at Simplehelp.net have figured out a way to hook up a webcam and and PC and use it as a security video camera. How cool is that. All you need is:
” 1. a PC running Windows 98, ME, 2000, XP (the software is untested on Windows 95 and NT, but should work)
2. a webcam (or two, see advanced)
3. Dorgem – an open source (free) webcam utility.
To upload images ‘off-site’ (in case someone steals your computer) you’ll need an FTP account. See the Advanced section when you’re done the initial setup.”
Great tutorial going step-by step with lots of screen shots.
