AN ELECTRONIC SECURITY SYSTEM WHICH USES TELEVISION CAMERAS, AUTOMATED SCENE ANALYZERS, AND ELIMINATES MUCH HUMAN ERROR IS DESCRIBED.
Abstract
ALL SECURITY SYSTEMS, INCLUDING ELECTRONIC, INVOLVE SURVEILLANCE, DETECTION, ASSESSMENT, AND RESPONSE. SURVEILLANCE SHOULD COVER THE SECURITY SYSTEM ITSELF AS WELL AS WHAT IS BEING GUARDED. DETECTION SHOULD INCLUDE FEW FALSE ALARMS, AND ASSESSMENT OF AN ALARM SHOULD BE AS RAPID AND ERROR-FREE AS POSSIBLE. FINALLY, A SECURITY SYSTEM SHOULD TELL PERSONNEL WHERE AN INTRUSION HAS OCCURRED AND WHETHER THE ALARM IS TRUE OR FALSE. IN A SECURITY SYSTEM WHICH USES CONVENTIONAL TELEVISION CAMERAS AND MONITORS, SELECTION OF CAMERA SITES IS IMPORTANT, WITH OUTDOOR SURVEILLANCE VIEDO INFORMATION WITH A DIGITAL SCENE ANALYZER ACHIEVES DETECTION AND ELIMINATES THE NEED FOR PERSONNEL TO MONITOR VIEWERS; THIS METHOD ALSO LEADS TO GREATER VIEWING ACCURACY. THE DIGITAL SCENE ANALYZER IS ACTIVATED WHEN AN ALARM IS REGISTERED. THE VIEW OF THE DIGITAL SCENE ANALYZER'S CAMERA IS AUTOMATICALLY DISPLAYED ON A SCREEN FOR SECURITY PERSONNEL AND A RECORD IS MADE OF THE ALARM; THE SYSTEM ALSO DETECTS OTHER ALARM SYSTEMS BEING USED AND ITS OWN ACTIVITIES AS WELL AS INTRUSIONS. WHEN WELL MAINTAINED, THE SYSTEM IS 95-TO 99-PERCENT ACCURATE. PERSONNEL ASSESSING AN ALARM ARE AIDED BY FLASHING MAPS. HOWEVER, PROBLEMS ARISE IF LARGE NUMBERS OF CAMERAS ARE ALARMED SIMULTANEOUSLY. THE SYSTEM GIVES SECURITY PERSONNEL GREAT ASSESSMENT CAPABILITIES AND SUMMARIZES ALL OF ITS ACTIVITIES IN PERIODIC REPORTS. CHARTS AND PICTURES ARE INCLUDED.
