This article identifies types of facilities that use various kinds of intrusion detection devices and considers influences on current intrusion detection sensor design, types of intrusion detection devices, and the future for such devices.

Abstract

Users of intrusion detection devices are high-valve industrial facilities (nongovernment sites whose penetration would endanger national security), commercial low-value industrial facilities, and residential facilities. High-value facilities use intrusion devices that include buried cables and 'triggered' fencing systems. Closed circuit television (CCTV) systems for general surveillance and assessment are also prevalent in such industries. The commercial low-value industrial sector is dominated by CCTV's and passive infrared devices. Vision systems built into CCTV's should increase. This will enable cameras to signal when objects not typical for the observed area enter the picture. Passive infrared sensors detect infrared radiation emitted by intruders. Interior microwave systems are currently limited to select applications in the commercial low-value sector. Microwave beams penetrate walls to detect movements. Sonic, shock, and vibration sensors detect early signs of intrusion attempts in open areas or through barriers. This article considers the likely future for each of the aforementioned types of devices.
