Alarm for your MacBook

If you've recently bought a new Mac laptop, the last thing you want is for it to get stolen. Apple doesn't really offer any monitoring program to protect your MacBook, so iAlertU comes as a blessing.

This open source program makes smart use of both motion sensor and iSight to protect your MacBook. Once activated, it will trigger an alarm as soon as your MacBook is moved or your keyboard/trackpad is touched.
It can also automatically take a snapshot of the robber with the iSight camera and send it automatically by email.
iAlertU is very easy to use and can be activated just by using the Apple Remote.
You can access all it's settings directly from the menu bar and choose what sort of alarm to trigger.
Obviously you'll have to choose well when to activate it, as you don't want the alarm to go off every time someone gets close to your Mac.

iAlertU is the first of its kind alarm system for your Apple MacBook computer. Basically iAlertU is a car alarm for your Apple Mac. iAlertU uses the built in sudden motion sensor (SMS) device to detect movement of your Apple MacBook and triggers an audible and visual alarm.

The alarm can also be triggered by keyboard and mouse/trackpad movement. The alarm is designed to continue sounding even after the Apple MacBook screen has been closed.

iAlertU is activated and deactivated using the infrared remote control included with every Apple MacBook computer. User adjustable settings let you decide which type of alarm triggers you would like to use, the duration of the alarm, and motion sensor sensitivity.

iAlertU also features functionality which utilizes the built in iSight camera to photograph the would be thief and then email the photo to a user specified email address.
