5 - Intrusion Detection Systems (IDS)
Characteristics
Automated or manual systems designed to detect an attempted physical intrusion, breach, or attack, the use of an unauthorized entry, or the occurrence of some specific event at an unauthorized or abnormal time
Synonym: burglar alarms
Examples
Simple circuit dry contact switch
Windows may include an internal wire grid or a surface-mounted foil strip that detects when the glass has been broken
Motion detectors
Digital motion detector (e.g. smart security camera)
Passive infrared (PIR) / heat-based motion detector
Wave pattern motion detector / microwave motion detector (low ultrasonic signal)
Capacitance motion detector (change in the EM field)
Photoelectric motion detector (changes in visible light)
Passive audio motion detector
Dual-technology sensors == 2 combined types to improve efficiency
Perimeter Breach detection
Contact devices (for window/door opening detection)
Based on Balanced Magnetic Switch (BMS)
Window closed = electric circuit closed
Infrared linear beam sensors / Light beam-based tripwire mechanism to detect entry
Intrusion alarms
Deterrent alarms (engage additional locks, shut doors)
Repellent alarms (audio siren, bell and turn on lights)
Notification alarms (record data about the event and notify admins)
Location categorization
Local alarm system (broadcast an audible sound)
Central station system (offsite monitoring agents)
Auxiliary alarm system (fire, police, medical services)
Secondary verification mechanisms
Additional alarms must be checked to reduce false positives
Requirements
Battery backup with enough stored power for at least 24 hours of operation
Incorporate a heartbeat sensor to ensure the connection remains effective
