Is your roommate like me, always stealing your food and clothes? Now you've got another way of catching him (or an actual criminal) with a Mac and iPhone duo from iVigilo. Keep tabs on your room and gear remotely.

The setup's pretty simple: install the iVigilo $5 app on your iOS device, ditto for your Mac, and then let your computer's camera keep an eye open for you. It'll beam video or timelapse pics over WiFi or 3G, and sports a motion trigger in case anyone tries to make off with the computer itself. Or, an enterprising thief can just close your laptop lid and plunder as he pleases. But it's better than having your friend sit there and watch out for you the entire time, I suppose. [iTunes]
