The system contains a motion sensor. In one embodiment a clock is in communication with the motion sensor. A processor is in communication with the motion sensor and the clock. The processor records a volume of motion sensed by the motion sensor as a function of time received in communications from the clock. An output device has a plurality of output signals. A plurality of threshold values stored in a memory is correlated with the output signals. A comparator is in communication with the output device, the memory, and the processor. The comparator compares the processor recordings to the threshold values stored in memory. Another embodiment of the system that detects disturbance of a fence includes motion sensor modules, a wireless transmitter, and a receiver at a command center. |
