An Integrated Monitoring System Using Intrusion Dectors

A personnel intrusion detection system, using passive infrared intrusion detectors, is described for monitoring unoccupied or seldom occupied areas of safeguards interest. The data from the detectors are analyzed and stored in a microprocessor-controlled, tamper indicating Data Collection Module. The data may be examined but not altered at any time through the use of a portable Inspector Display Module, which contains a numeric keypad, functional keyboard, and a printer. If the Data Collection Module detects a signal from any passive infrared intrusion detector indicating an alarm condition exists, it triggers a portable television system to record several video frames of the scene of interest for later viewing by the Inspector.
