This is pretty cool: preyproject.com.
You install a small piece of software on your laptop or phone. If you lose the device, log in to the Prey web site and change the device’s status to Missing. The software will capture a screen shot, webcam shot, geographical location (using GPS or WiFi triangulation), and a bunch of system and network info. You can even sound a loud siren through the speakers if you think the device is nearby. I tested it on a laptop and it geo-located it within one house!
Up to three devices are free; Pro plans are available. Works with Windows, Mac, and Android.
I read about Prey in the article 4 simple steps to bulletproof laptop security. Besides, theft and loss recovery, the article also describes strong passwords, fingerprint readers, and full-disk encryption, all of which I’m already using.
