    Study Notes

    Physical Security

    • Physical security is the system of barriers between intruders and the protected assets.
    • It aims to prevent unauthorized access, espionage, sabotage, damage, and theft.
    • Safeguarding personnel from criminal acts is also included in physical security.

    Principles of Physical Security

    • Physical measures are essential to deny unauthorized access due to persistent threats.
    • Enemy agents actively seek information, and no barrier is truly impenetrable.
    • Defense-in-depth involves multiple barriers to enhance security.
    • Surreptitious entries are difficult to detect and pose greater security risks.
    • Each installation has unique challenges and requires tailored security measures.

    Barriers Defined

    • Barriers are physical structures that restrict, deter, or prevent unauthorized access.
    • Building walls, fences, and bodies of water serve as perimeter barriers.
    • Bodies of water alone are insufficient as primary barriers.

    Additional Protective Measures

    • Top guard is an overhang barbed wire placed on the perimeter fences for added security.
    • Guard control stations are manned posts at perimeter entrances for surveillance.
    • Towers provide psychological deterrence and improve visibility.
    • Signs and notices convey information, directions, and warnings.

    Perimeter Guard

    • Fixed post guards are stationed at specific locations within the compound.
    • Patrol guards actively move around the premises for regular surveillance.

    Security & Protective Lighting

    • Lighting provides illumination for identifying persons or objects and acts as a deterrent.
    • Perimeter lighting is an essential part of security systems, working alongside fences and guards.

    Purposes of Protective Lighting

    • Provides sufficient illumination during hours of darkness.
    • Improves visibility for guards and intruder identification.
    • Creates a psychological deterrent against intrusion.

    Importances of Protective Lighting

    • Serves as a deterrent to violators.
    • Assists the security force in surveillance and apprehension.

    Intrusion Alarms

    • Alarms are activated by various methods to alert security personnel.
    • Foot rail activators allow tellers to trigger an alarm without raising suspicion.
    • Bill traps are placed in teller drawers and trigger alarms when currency is removed.
    • Knee or thigh buttons are activated with pressure for discreet alarm activation.
    • Foot buttons provide safe activation with hands in view of the intruder.
    • Double squeeze buttons require pressure on both sides to minimize accidental activation.

    Types of Alarm Detection System

    • Central Station System: Connects to a remote panel at a private owned protection Service Company. Alarm signal is transmitted over telephone lines.
    • Local Alarm-By-Chance System: Sounds a bell or siren for a local response.
    • Dial Alarm System: Automatically dials a preset number when activated, with a recording of intrusion.

    Three Parts of an Alarm System

    • Sensor or Trigger Device: Detects the intrusion.
    • Circuits: Carry messages to the signaling apparatus.
    • Signaling System: Communicates the alarm.

    Desirable Characteristics of Intrusion Alarm Systems

    • Able to be activated by human personnel.
    • Provides audible and visual signals, indicating the location of the incident.
    • Has a fail-safe feature that signals when a system malfunction occurs.
    • Difficult to tamper with or disable.
    • Monitoring console with operational controls, with wireless or wired transmission.

    Perimeter Protection

    • First line of defense against intruders.
    • Intrusion alarm devices are placed on doors, windows, vents, skylights, and other openings.
    • This type of protection is crucial as most break-ins occur through these openings.

    Area and Space Protection

    • Detects intrusions inside the building.
    • Indoor detection devices utilize motion detectors.
    • Motion detectors use infrared or microwave technology to detect movement.

    Intrusion Detection System (IDS)

    • Electronic devices used for detecting entry or attempted entry of intruders.
    • Provides 24-hour surveillance, reducing the need for constant patrolling.
    • Can be used with closed-circuit television (CCTV) systems.

    Limitations of IDS

    • Susceptible to circumvention if not carefully selected or installed.
    • May have high false alarm rates.
    • Requires skilled maintenance.

    Perimeter Intrusion Detection System (PIDS)

    • Electronic devices used to detect entry or attempted entry across the outer perimeter.
    • Offers similar advantages as IDS.

    Limitations of PIDS

    • Prone to high false alarm rates.
    • Expensive to install and maintain.
    • Vulnerable to deliberate alarming.
    • Can be bypassed by knowledgeable intruders.

    Types of Perimeter Intrusion Detection System (PIDS)

    • Linear Microwave System: Uses a microwave beam between a transmitter and receiver, covering distances of up to 150 meters.
    • Radiating Cable System: Coaxial cables are buried 2 meters apart, with radio frequency transmitted through apertures. Intrusions disrupt the frequency field, triggering an alarm.
    • Vibration Sensors: Detects forced entry through walls, ceilings, doors, and other rigid structures.
      • Inertia Switches: A ball inside a capsule moves with vibration, breaking electrical contacts.
      • Geophones: A spring-loaded magnet moves relative to a coil, inducing a current when vibration occurs.
