  1. PHYSICAL SECURITY • A system of barriers placed between the potential intruder • It is the matter to be protected

  2. Protective Barriers • Structural • Human • Animal • Natural • Energy

  3. Types of Fencing • solid • full - view Barbed Type • fabricated from a steel strip with 500 pounds breaking system • Over – all width is ¾ of an inch Top Guard • is an overhang of barbed wire along the top of the fence

  4. Chain – Link Fencing • The most frequently used fencing for security purposes Doors – Special Features • Security of a fire door is enhanced by use of audible alarms

  5. Windows • burglary – resistant glass • protective iron or steel brass • a good grade of heavy steel mesh • chain – link fencing Miscellaneous • sidewalks elevators • utility tunnels • operational tunnels • storm sewers • storm doors

  6. ALARM SYSTEM Actuator • A magnetic switch or thermostat that will cause system to alarm Annunciator • It is the visual of audible signalling device Capacitance • Two or more object which enables them to store electrical energy

  7. Capacity Proximity Sensor • Used to detect attempted penetration into safer or storage cabinets Conductor • Material which transmit electric current Control Unit • The terminal box for all sensors

  8. False Alarm • Activation of sensors for which no cause can be determined Intrusion Detection System • Combination of components including sensors, control units, and monitor units Intrusion Detection Sensors • An alarm signals by sensing the stimulus, change or condition

  9. Local Audible Alarm • An electronic bell for outdoor or indoor use in the vicinity of the protected area Monitor • A device that senses and reports in the condition of a systems
