Abstract
A tampering detection apparatus is used to determine the occurrence of unauthorized tampering with a barrier. At a tampering detection apparatus, a quantity during an operation of the movable barrier is sensed without actuating a magnetic switch. The quantity is potentially indicative of unauthorized tampering with the movable barrier. A determination is made as to whether the quantity is within a valid operating range. When the quantity is not within the valid operating range, a warning is issued to a user. The warning indicates a potential tampering with the movable barrier.
