If your laptop or Mobile (Android) has been stolen, then there is a way you can get it back right away and catch the stealer (thief) red handed. This program uses internet connection to send you information of stealer's whereabouts and if thief is not connected to internet, the program attempts to connect to the nearest open wifi access point available. This gives you a better chance to locate the device. Prey helps you locate your missing laptop or Mobile by sending timed reports with a bunch of information of its whereabouts. This includes the general status of the computer, a list of running programs and active connections, fully-detailed network and wifi information, a screenshot of the running desktop and — in case your laptop has an integrated webcam — a picture of the thief (a picture of the guy who’s using the computer). What more could you ask.
