Hey .
Prey is a lightweight application that will help you track and find your laptop and android phone if it ever gets stolen. It works in all operating systems and not only is it Open Source but also completely free. so basically you install a tiny agent in your PC or phone, which silently waits for a remote signal to wake up and work its magic.
Prey Features:
- Prey uses either the device's GPS or the nearest WiFi hotspots 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.
- Wifi auto-connect If enabled, Prey will attempt to hook onto to the nearest open WiFi hot-spot when no Internet connection is found.
- Watch their movements : Grab a screen shot of the active session -- if you're lucky you may catch the guy logged into his email or Facebook account!
- Scan your hardware : Get a complete list of your PC's CPU, motherboard, RAM, and BIOS information. Works great when used with Active Mode.
- No unauthorized access : Fully lock down your PC, making it unusable unless a specific password is entered. The guy won't be able to do a thing!
- Light as a feather : Prey has very few dependencies and doesn't even leave a memory footprint until activated. We care as much as you do.
- Keep your data safe: Hide your Outlook or Thunderbird data and optionally remove your stored passwords, so no one will be able to look into your stuff.
- Full auto updater: Prey can check its current version and automatically fetch and update itself, so you don't need to manually reinstall each time.
