Inventing Safe or Sound

Safe or Sound (SOS) is a revolutionary product security alarm. It locks to the product with reinforced steel without causing any damage.

When the product is moved a certain distance from a fixed transmitter, the alarm on the product sounds. This alerts the shop/security personnel and also scares the thief.
