The WallAlert detects vibrations caused by attempts to disturb solid structures including fixed warehouses, bank vaults, safes, and perimeter walls. The WallAlert can be installed in new or existing security systems and offer a higher level of protection and false alarm immunity than traditional shock sensors, which often lack the ability to discriminate between ambient vibration and real attacks. The WallAlert Sensor cable is an ideal system for all types of walls and drywall to detecting mechanical vibration transmitted along the wall as an intruder attempts to break through the wall.
