Orbicule has released a beta version of TheftSensor, its innovative alarm software for the MacBook Pro.

The software uses the Mac's built-in Sudden Motion Sensor software as part of an alarm system, which works just like a car alarm.

MacBook Pro owners can enable the TheftSensor software by pressing the play button on their Apple Remote. When enabled, TheftSensor will sound a loud alarm whenever the MacBook is moved, lifted or when its lid is closed. The alarm can be disabled by pressing the play button a second time.

More information on the product and a movie demonstration are available online. The beta is available as a free download to encourage feedback from Mac users.
