and watches the individual enter. The person places any hand-carried objects
in the material inspection station, steps into the IDS area, and stops in
front of the identification console. As the person walks into the IDS area,
the SNM and metal detectors take measurements to sense for and indicate to
the operator the presence of SNM or metal. While the individual is being
identified, the explosives detector samples the air around the individual and
indicates to the operator the presence of explosive vapors. After the
individual has been identified and if no alarms have been signaled by any of
camera can be used to examine material which has caused a metal detector to
alarm. The individual removes items from his pockets and places them in the
material inspection area. The operator at the control console pushes a
button and views the material on the television monitor. The person in the
enclosure again passes through the metal detector. The material inspection
area is large enough to view lunch boxes, briefcases or packages.

types of sensors available and typically deployed. Sources of more detailed

Function and Location
Overview. For security guards to respond to an intrusion, threat
detection either by security personnel or remote systems IDS is required.
The function of an exterior perimeter IDS is to detect a threat and initiate
the security system response timeline at the exterior perimeter of the site.
IDS performance parameters of concern include:
Completeness of coverage.
False and nuisance alarm rates.
Probability of detection.
Zone at which the alarm occurred.
