Prey - Anti-theft Software For Windows, Mac, Linux & Android Phones

Prey is a free and open-source software, it helps you keep track of your phone or laptop at all times, and will help you find it if it ever gets lost or stolen.

Latest Prey features include wifi autoconnect, an alarm system, screenshot grabbing, hardware scanning and webcam capturing, etc. All of these functions are managed as modules, which can be activated on demand by the user, and new functions can be added by adding new modules.

 How it works
  1. First of all, you need to install Prey in your PC or phones.
  2. Set Reporting mode and create your Prey account, then it will run silently and wait for a remote signal to wake up.
  3. Once you device is lost, you should login to Prey web control panel and report your device is missing.
  4. After that, Prey will send you informations regarding the device's location, hardware and network status, etc.
Note: The free account only free for 3-device and 10-reports. Anyway, this is just a software (and network connection is needed), it'll fail to work once your operating system is damaged, do not forget that.
