4. What your first thought about building security system?

5. What is Building Security System ? • protect from unwanted incident • safeguard personnel • assures safety • freedom from risk or danger

6. What are some of the conventional building security methods exist in Malaysia?

7. PADLOCK

8. SECURITY DOOR LOCK

9. Spikes atop a barrier wall

10. Defendius Labyrinth Security Lock Every time you open the door that makes you solve a maze to unlock it

11. Do you know what is the most common home security method among the Chinese in Malaysia?

13. Safety and security??

14. Safety vs security • There is a very thin line that separates safety from security in buildings • Definition (safety and security) • “safety is taken to mean the protectionof the occupants of the building (and a lesser extent their possessions) from accident; while security is assumed to mean protection from willful attack those occupants, their possessions and the actual property they occupy” – Marsh (1985)

15. Safety vs security Therefore the difference between safety and security is very much depending on situations – one is unintentional while the other one is intentional. e.g. In case of a fire - Normally it is unintentional – therefore it involves safety - If it is an inflammable (combustible) – it involves security

16. 2.0 PURPOSE OF BUILDING SECURITY - To control intruders from entering the buildings or the properties - To protect valuable belongings which the effectiveness is dependable on the building design

17. 3.0 LEVEL OF BUILDING SECURITY • Depends on several factors • - Location of buildings • - Purpose of buildings • - Socio economy of surrounding neighbourhood • - Equipment/system installed • 3 levels of security • - Low level security • - Medium level security • - High level security

18. i. Low Level Security - Normally for residential and small scale commercial buildings - Additional locks at main entrance, chain etc. as well as for windows - Alarm system only for 1 or 2 zones within the premise - Fire alarm is separated from the security systems since the possibility of fire is higher compared to intrusion

19. ii. Medium Level Security • - Applied to medium size industrial and commercial buildings • Use of keys in buildings is monitored and controlled • - Stand-alone card reader for certain areas in buildings • - Anti-vandal protection equipment & anti-bandit glazing at high risk area such as exhibition area • - Use of CCTV at entrance point

20. iii. High Level Security - Applied to big scale commercial buildings and industrial building complex - Advance and extensive entrance monitoring system plus recording system - Integrated & centralized security management & monitoring system - Centralized system directly connected to authorities - Automatic intruder sensors, fire alarm & comprehensive CCTV

21. What level of security needed? High level

22. What level of security needed? Medium level

23. What level of security needed? Medium level

24. What level of security needed? High level

25. What level of security needed? Low level Medium level

26. This place need a security system? ? Low level

27. What level of security needed? High level

28. 4.0 SECURITY SYSTEM COMPONENTS • Outer Perimeter control • Lighting • Access control • Pedestrian traffic control • Intrusion detection (alarm) • Video Monitoring

29. 4.1 Outer Perimeter Control Man-made structural protective barriers (such as fences, walls, floors, roofs, grills, bars, roadblocks, signs, or other construction) used to protect a facility's potential access ways, restrict, channel, or impede progress.

30. Why Perimeter Control? • Control access to all building entrances • Enhance perimeter security • Restrict or to channel potential access ways

31. 4.1 Outer Perimeter Control • The most common type of structural outer perimeter barrier is the fence.  • However, it isn’t good enough to simply throw up a fence and call it a day.  • Instead, your fence, a preventive device, should be supported by one or more additional prevention and detection controls.  • The number of controls you implement and to what extent are dependent upon the risks your building or property faces.

32. Fence basics • A fence is both a psychological and a physical barrier.  • The psychology comes into play when casual passers-by encounter it.  • It tells them that the area on the other side is off-limits, and the owner would probably rather they didn’t walk across the property.  • A fence or wall of three to four feet is good enough for this.

33. 4.1 Outer Perimeter Control • For those who are intent on getting to your data center or other collection of information assets, fence height should be about seven feet.  • For facilities with high risk concerns, a top guard is usually added.  • The top guard consists of three to four strands of barbed wire spaced about six inches apart and extends outward at a 45 degree angle.  • The total height, including fence and top guard, should reach eight feet.

45. 4.2 Lighting One of the most basic (and cheapest) components of a security system. Carefully designed and coordinated interior and exterior lighting systems can exert a significant deterrent (prevention) effect

46. Purpose of Lighting? Security lighting may be provided to aid: 1. Detection of intruders 2. Deter (prevent) intruders 3. Simply to increase the feeling of safety.

47. Types of Lamps • Types of Lamps Used in Outdoor/Indoor Lighting: • Incandescent • Fluorescent • Metal Halide • High Pressure-Sodium • Low Pressure Sodium

48. Types of Lamps • Incandescent • most familiar to homeowners • used for the majority of residential lighting, both indoor and outdoor. • commonly used in applications where such low outputs are needed and where the lighting is often switched off and on. • Advantages: low capital cost for lamps and luminaries, wide availability, wide variety of both lamp and fixture types, lack of hazardous wastes. • Disadvantages: short lifetimes, low efficiency with resultant high per-lumen energy use and life cycle cost, attraction of insects

49. Types of Lamps • 2) Fluorescent • predominate in indoor retail and office uses, and are occasionally seen in outdoor area lighting • available in the so-called "compact" styles • Advantages: low life cycle costs, high efficiency compared to incandescent, no warm-up period, good colour rendition, and long lifetimes • Disadvantages: higher initial costs compared to incandescent lamps, large lamp size, low efficiency, poor output maintenance

50. Types of Lamps • 3) Metal-Halide • Light is produced by the passage of an electrical arc through a small tube filled with mercury vapour and metal halides at 2-4 times atmospheric pressure. • Advantages: a wide variety of moderate to high luminous output lamps, high efficiency compared to incandescent and mercury vapour, and good colour rendition. • Disadvantages: lower efficiency and output maintenance compared to high- and low-pressure sodium, shorter lamp lifetime compared to high-pressure sodium, colour changes, ultra-violet output if not adequately filtered
