Entry-Control Approaches
(Chapter 4 Entry-Control Technologies, Continued)

Once entrances to a facility are limited in number, the process of allowing or denying access is generally accomplished through one of four approaches. The first and most common approach is manpower intensive, and the remaining three employ technology devices. The level of actual security achieved is generally believed to be from 1 to 4, lowest security to highest security, but this is subject to many other variables. These four approaches are:

A security guard controls entry; ID cards or other means of identification may be checked. (WHO lets you in)

A special ID card/badge with automatic readers. (What you HAVE)

A PIN number for entering on a keypad. (What you KNOW)

A biometric device for feature recognition. (Who you ARE)

Who you ARE

An electronic device verifies the identity of a person through the use of a personal attribute, such as hand or finger shape, fingerprint, voiceprint, signature dynamics, retinal pattern, or iris pattern (exhibit 4.4). These devices, known as biometric identifiers, can be very accurate. The chances of such devices mistakenly allowing an unauthorized person into a facility is usually much lower than the chances of a guard inaccurately matching faces to picture badges. Biometrics are commonly used in high-security applications where unauthorized access into a facility is unacceptable. Recently, two elementary schools in New Mexico have been using hand geometry systems to verify custodial parents, as the abduction of a child by a noncustodial parent is one of their greatest vulnerabilities.

An identification alarm—a portable device that identifies the owner of the device.

An identification/location alarm—a portable device that identifies, locates, and tracks the person who activated the duress alarm.

. The Global Positioning Satellite (GPS) technology that is currently identifying, locating, and tracking everything from military soldiers to car rental vehicles has not been shown to be as successful when used inside buildings or around large or tall buildings. GPS requires an unobstructed signal from the ground transmitter unit to an Earth-orbiting satellite. Some advanced duress systems use a hybrid design that tracks outside personnel with GPS technology and RF or infrared systems for tracking personnel inside facilities.
