This perimeter intruder detection system (PIDS) is a system applicable to surveillance and perimeter control of areas of responsibility where risks are assessed, like swimming-pools, school precincts, museums, embassies, warehouses, and the like. It consists of a string of an arbitrary number of spaced but communicated micro-controllers, each one driving infra-red (IR) and/or ultrasound emitters and digital output transducers. The system uses radar effect and it carries continuous perimeter patrol by performing sequential surveillance of detector outputs as well as distributed pattern recognition analysis. All micro-controllers support a common code which includes turning the emitters sequentially on and off, pattern recognition routines, and serial transmission of alarm byte. Butterfly alarms are avoided via software and adequate geometrical configuration of the emitter beam net. One master micro-controller closes the string synchronizes and conducts the others. When the master micro-controller receives the "intruder" signal, it triggers the physical alarm, its next order being to restart patrolling.
