How to track your laptop or Android cell phone if it's stolen.
There are obvious reasons to like Prey. Chief among them, it's free to use for up to three devices of any kind, from computers running Windows, Mac, or Linux to Android devices. But that wouldn't mean anything if the tracking Prey provided wasn't really solid. It's not fool-proof, especially if the thief wants to entirely wipe your computer or phone, but if that's not the case, it gives you a fighting chance.
We'll tell you why in readable text, being a blog and all, but we think our video walkthrough, embedded above, tells the tale even better—with old-timey music, too, courtesy of Incompetech.
On a laptop with a webcam, a Wi-Fi chip, and Prey installed, it's a good bet you'll have a photo of your thief and an approximate location on them just as soon as they have your computer running for a few minutes. You don't have to actively search, either—devices with Prey installed in the background "phone home" to your web-based account every 20 minutes by default (you can decrease this interval), spilling their guts about everything they're doing.
Because it's tracking software that doesn't want to be seen, Prey is almost invisible when it's running on your system, without any configuration or executable files to be seen. In fact, once you've deleted the installer, you shouldn't be able to find Prey at all in your system, because that's the idea. It quietly and quickly checks in with Prey's servers in the background, at an interval you decide, to see if the owner has logged in and marked it as stolen. That's all it does—until you flip the switch on Prey's servers to note that it is, in fact, stolen, or ask for an update on the hardware profile.
