New Zealand Ministry of Justice's The Seven Qualities for Well Designed, Safer Places

Avoid using elements that create a poor image or a fortress like appearance. Integrate security features intrinsically, unobtrusively.

32

Garages

Threats - crime and vehicles hitting pedestrians. Use CCTV. Lighting 10-12 foot candles over parked cars and 15 to 20 foot-candles in walking and driving aisles. Exterior lights - 12 feet above ground and point downward and paint walls white to reflect light. And lights should be strategically placed to reduce dark corenrs where criminals or attackers could hide. elevators and walups should be in a lobby outside of a controlled space.

33

Infrared

Can not be seen by human eye, covert surveillance

34

Primary function of Access Control System (ACS)

Ensure that only authorized personnel are permitted inside the controlled area. Goal is to limit the opportunity for a crime to be committed.

35

Magnetic strip cards

Are easily duplicated

36

Proximity cards

Use embedded antenna wire connected to a chip within the card

37

Smart Cards

Credential cards with a microchip embedded in them. Can provide PIV - Personal Identity Verification

38

CCTV

Provides immediate output, can be used for surveillance, assessment, deterrence, evidentiary archives

39

3o frames per second

higher than what is needed for evidentiary and investigative purposes

40

MPEG - Moving Picture Experts Group

most common compression algorithm - ration 10 to 100

41

DVRs

Typically have 8 or 16 port versions - equals number of cameras that can be used

42

Balanced Magnetic Switch - BMS

Uses a magnetic field to determine if an alarm signal is initiated - not susceptible to external magnetic fields, used on doors and windows

43

Motion activated cameras

sends an alarm when intruder enters field of view

44

Acoustic sensors

activated when building is secured and unoccupied

45

Infrared linear beam sensors

a focused infrared red light beam is projected from an emitter and bounced off a reflector that is placed at the other side of the detection area

46

Passive Infrared Sensors

most common - no beam is why it is called passive - picks up heat signatures - motion detector will not detect person standing still, also used a automatic request to exit locked doors

47

Dual technology sensors

helps lower false alarm rates - integrated, redundant devices must react at the same time to cause an alarm

48

Anti - passback

card reader is utilized on both entry and exit

49

rim lock

associated with a dead bolt type of lock

50

mortise lock

lock or latch that is recessed

51

locking cylinders

pin tumbler contained within plug

52

cipher lock

typically 5 to 10 digits

53

false rejection

failure to recognize a legitimate user

54

false acceptance

erroneous recognition - accepting an imposter

55

hand geometry

tends to give high false accept rates

56

iris scanning

most accurate and secure, people timid about having eyes scanned, throughput is 2 seconds

57

retinal scanning

blood vessels back of the eye - takes 10 seconds - typically used in high end security application

58

vascular patterns

ultimate palm reader - difficult to forge, contact-less, many and varied uses, capable of 1:1 and 1:many matches

59

MTBF - Mean time before failure

latent damage of equipment - weakened by stress
