Anti-Theft Feature

There is a piezoelectric sensor attached to the locker for the Anti-Theft feature. Whenever someone tries to break the locker or move it from its original position, the locker will detect the vibration and send SMS to the owner stating Locker under threat. Since SMS is tend to be ignored sometimes, the locker will subsequently call the owner to aware him about the emergency situation.
