A DESCRIPTION OF THE J-SIIDS AND ITS COMPONENTS PLUS GUIDELINES FOR THE SELECTION OF INTERIOR INTRUSION DETECTION DEVICES FOR SECURE AREAS.
Abstract
THE J-SIIDS IS DESIGNED TO GIVE IN-DEPTH SECURITY TO THE PROTECTED ROOM OR BUILDING. IT IS DESIGNED TO MEET THE THREAT POSED BY THE SEMISKILLED INTRUDER WHO CAN BE EXPECTED TO ATTEMPT ENTRY WITHOUT DETAILED PLANNING OR SOPHISTICATED EQUIPMENT AND MAY WORK INDIVIDUALLY OR AS A MEMBER OF A SMALL GROUP. THIS INTRUDER CAN BE EXPECTED TO ATTACK THE LOCKS, DOORS, WINDOWS, VENTS, WALLS, FLOORS, AND CEILINGS OF THE PROTECTED AREA, OR HE MAY BE A 'STAYBEHIND' TO REMOVE ITEMS AFTER THE AREA IS SECURED. HE MAY BE EXPECTED TO RESORT TO ROBBERY BY CONFRONTING WORKING PERSONNEL OR GUARDS. THE SYSTEM IS DESIGNED WITH THREE LEVELS OF DETECTION CAPABILITY IN MIND. THE FIRST LEVEL IS BOUNDARY PENETRATION DETECTION, THE SECOND IS MOTION DETECTION, AND THE THIRD IS POINT DETECTION. THE OUTERMOST LEVEL, PENETRATION DETECTION, IS PROVIDED BY THE PENETRATION SENSORS AND GIVES THE REACTION FORCE MONITORING THE SYSTEM THE EARLIEST NOTICE OF AN ATTEMPTED INTRUSION. THE MOTION SENSOR PROVIDES THE SECOND LEVEL OF PROTECTION AND DETECTS AN INTRUDER ONLY AFTER HE HAS ENTERED THE SECURE AREA. THUS THE ALLOWABLE RESPONSE TIME GIVEN THE REACTION FORCE IS SHORTER THAN THAT GIVEN BY THE PENETRATION SENSORS. THE INNERMOST LEVEL OF DETECTION CAPABILITY, POINT DETECTION, IS PROVIDED BY THE POINT SENSORS. THESE SENSORS DETECT ATTEMPTED REMOVAL OF PROTECTED ITEMS AND GIVE THE REACTION FORCE AN ALLOWABLE RESPONSE TIME WHICH IS SHORTER THAN THAT GIVEN BY THE FIRST TWO LEVELS OF DETECTION CAPABILITY.
