Factors which Affect sensor Selection for intrusion Detection System

Areas which require physical protection systems are usually those in which very valuable material, potentially dangerous material, or strategic information is stored. The primary purpose of the physical protection systems for such areas is to prevent theft or sabotage of the protected items. Intrusion detection is one of the essential elements of a physical protection system. It is essential that any new or to-beimproved intrusion detection system be carefully planned and analyzed to ensure that it will reliably perform its intended function in the specified environment and that the system be identified and understood. Details about particular types of sensors and how they operate are given in the references listed and are not repeated here. The performance of intrusion detection sensors is influenced by a complex interrelationship of a large number of factors. Some of these factors for exterior and interior sensors to be used in intrusion detection systems are identified and discussed. 1s strengths and weaknesses
