iAlertU is the first of its kind of alarm system for your Apple MacBook computer. Basically iAlertU is a car alarm for your Apple Mac. iAlertU uses the built in accelerometer and other sensors to trigger an alarm and the iSight camera to capture an image of the thief. iAlertU can be configured to email details of the alarm event to a specific email address. In addition to this you can tell iAlertU to execute an Applescript when the alarm goes off. Some people use this to generate SMS alerts. With v0.71, the developers of iAlertU added a new interface that can be used by an external, authenticated application to control iAlertU, request photo’s, and other information captured by iAlertU. The first such application is uAlertMe, an iPhone app available on Apple’s app store (for more information, visit the developers webpage at http://www.pkclsoft.com/pkclsoft/ualertme.html).
