ASSESSING THE CAUSE OF AND THE APPROPRIATE ACTION TO TAKE IN RESPONSE TO A SECURITY SYSTEM ALARM SOUNDOFF CAN INCLUDE A VARIETY OF MEASURES BUT FINAL DETERMINATION MUST DERIVE FROM OBSERVATION OF THE ALARM AREA.
Abstract
INFORMATION ON CAUSE CAN BE DERIVED THROUGH PROPER APPLICATION AND PROCESSING OF SENSOR DATA, BUT DIRECT OBSERVATION CAN BE PERFORMED BY SECURITY PERSONNEL FROM THE PERIMETER, OR REMOTELY BY CLOSED CIRCUIT TELEVISION, REAL TIME COINCIDENT WITH THE ALARM, OR DELAYED POST-EVENT ANALYSIS. AT THE REFERENCE SITE, TWO OBSERVATION TOWERS PROVIDE VISUAL ACCESS TO THE ENTIRE PERIMETER. SENSORS PROVIDE INFORMATION TO ROVING PATROLS FOR DELAYED ASSESSMENT. MULTIPLE ALARMS MAY CREATE AN OVERLOAD SITUATION FOR REAL-TIME ASSESSMENT, AND THE RECORDING OF THE SCENE MAY BE REQUIRED. THIS IS HANDLED THROUGH USE OF A VIDEO DISC SYSTEM. THE BASIC CLOSED CIRCUIT TELEVISION SYSTEM AND ADEQUATE LIGHTING EQUIPMENT MUST BE SELECTED TO PROVIDE SUFFICIENT RESOLUTION OF THE OBSERVED AREA. THE VIDEO TRANSMISSION LINES ARE SUPERVISED BY MONITORING THE QUALITY OF THE VIDEO PICTURE. ASSESSMENT CAN REPRESENT A LARGE FRACTION OF THE INSTALLATION COST OF A PERIMETER INTRUDER DETECTION SYSTEM, AND THE ASSESSMENT SUBSYSTEM IS CLOSELY RELATED TO THE SENSOR SUBSYSTEM. ILLUSTRATIONS AND REFERENCES ARE PROVIDED. (TWK)
