Determination of the Degree of Protection.
Each type of IDS is
designed for a specific type of protection. Therefore, security personnel
must analyze and make a determination on the degree of protection.
Protection is dependent upon the following factors:
a. The threat.
What criminal activity is being deterred, burglary,
b. The value of assets?
c. Location of the building, room, open area or closed area.
d. Construction of the building or room.
e. Degree of physical security afforded by safes, cabinets, racks,
locks, and other supportive security measures.
f. The effectiveness of the intrusion detection system.
g. The responsiveness of the reaction force to the reported intrusion.
Intrusion detection alarm systems should be inherently stable. They should
be durable, reliable, and maintainable.
These devices are designed to
detect, not prevent; they should be used as an adjunct to, not a substitute
for, the security force. There are various types of alarm systems. All of
them have certain advantages and disadvantages.
of an alarm system include the following:
a. A detection unit or detection components (normally called sensors).
These are located at the protected area. They are designed to initiate an
alarm upon intrusion of an intruder into the area. They will alarm, also,
upon the approach of a human to a protected object.
These lines conduct the alarm signals
from the protected area to a central annunciator panelboard.

components. This panelboard announces by both visible and audible signals.
It alerts upon intrusion into protected areas and the structure of location
d. Fail-safe features.
These give a signal at the annunciator
panelboard when abnormal operating conditions keep the alarm system from
e. Other features.
These are features which make this system less
vulnerable to agents trained to circumvent detection. Such features should
