Intrusion Detection Systems in physical security

The chapter considers Intrusion Detection Systems (IDS) when applied in the protection of assets as a Defence in Depth strategy. Defence in Depth deters, detects, delays and responds. IDS is an automated technology that deters, detects and communicates the presence or attempted presence of a person or object intruding within a designated zone. Elementary to successful detection are IDS sensing detectors, in which detect is achieved by the geometry of detection through the anticipated intrusion vector. Sensing detectors have a field of view exposed to a designated zone, where the sensor is stimulated when exposed to a compatible person or object through emitted or reflected energy, a pressure wave or molecular decay. There are a taxonomy of sensing detectors, categorized by either the dimension of detection or more commonly, application. Dimension of sensing detectors range from zero to four dimensions, whereas application range from internal or external and mounted, free-standing or buried. Efficacy factors of IDS include their degree of deterrence, the probability of intrusion detection and whether IDS alters deviant behaviour. Finally, application issues include the nuisance alarm rate, electronic security sector and its regulatory regimes, and future trends in IDS are considered.
