Abstract

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 and initiates one of the plurality of output signals when the processor recordings exceed at least one of the threshold values. In another embodiment there is provided a system for detecting disturbance of a fence, comprising a plurality of motion sensor modules, each motion sensor module comprising a processor in communication with the motion sensors for distinguishing between a benign motion event and a fence disturbance event, and a wireless transmitter in communication with the micro-processor for transmitting signals when a possible fence disturbance event is detected; and a receiver at a command center for processing signals from the wireless transmitter and for signaling a possible fence disturbance event.
