A Microcomputer Based System for Intrusion Detection Display and Assessment

A system has been developed to aid in assessing intrusion alarms. Capabilities include color graphic and text displays, prioritized alarms, a high-speed dual loop communications system, a customized function keyboard for operator input and microprocessor controlled Closed Circuit Television (CCTV) and videodisc recording subsystems. The system, which is implemented on an DEC LSI-11/23 utilizing RSX-11S, is designed for use by an operator with no knowledge of computers. Most of the assessment functions can be performed with single keystrokes. During multi-alarm situations, the system manages the display, presenting information about the highest priority alarms to aid in operator assessment. Although the system prioritizes alarms, the operator is free to assess alarms in any order. The system supports multicenter operations. One center is responsible for assessing all alarms and is monitored and backed up by another center.
