So how hard would it be to rig one of these to a motion detector and a timer so that it recorded for, say, 5 minutes every time it detected someone... er.... opening a door?
That's exactly what I was hoping for.
A couple jobs ago, one of my coworkers had someone getting on one of the lab computers after he left for the day, surfing 'inappropriate' websites. For fun, he setup a webcam and some software that detected motion and then started recording just like you described. He also captured the surf history, etc. Sure enough he forwards me the videos of some cleaning crew dude with a vacuum on his back getting on the computer and searching for things like 'paladas vaginas'.
The intense look on his face as he viewed the pages was so damn funny.
I've also had stuff disappear from my desk at work many times. Would be nice to bust someone with a motion detecting cam like that.
