Consider Prey for your laptop...
PDF version
Prey is an open source application, available for Windows, Mac, and Linux, that can help you out when your laptop is stolen.
Prey takes an ingenious approach to laptop recovery; because once it is
installed, it will send timed reports to a configured email address
containing information describing its whereabouts.
- The information collected includes:
- Status of the computer
- List of running programs and active connections
- Detailed network and WI-FI report
- Screenshot of running desktop
- A picture of the thief (if the stolen laptop is equipped with a Webcam)
