Prey lets you keep track of your laptop or tablet whenever stolen or missing -- easily and all in one place. It's lightweight, open source software that gives you full and remote control, 24/7.
Basically you install a tiny agent in your PC or tablet, which silently waits for a remote signal to wake up and help you find it. This signal is sent from the Internet, and allows you to gather information regarding the device's location, hardware and network status, and optionally trigger specific actions on it.
You can quickly find out where your computer is located, who's using it, and what he's doing on it thanks to Prey's powerful reports system.
100% Geo-location aware.
Prey uses either the nearest WiFi hotspots or the device's GPS (in case of Windows 8 tablet) to triangulate and grab a fix on its location. It's shockingly accurate.
Know your enemy.
Take a picture of the thief with your laptop's webcam so you know what he looks like and where he's hiding. Powerful evidence.
Watch their movements.
Grab a screenshot of the active session -- if you're lucky you may catch the guy logged into his email or Facebook account.
Keep your data safe.
Hide your Email data and optionally remove your stored passwords, so no one will be able to look into your stuff.
