Automation systems in the security of industrial facilities

This paper presents selected electronic and mechanical technical security systems used in the perimeter protection of industrial facilities. Modern systems incorporating the latest technological solutions utilize computer video detection, electromagnetic detection, fiber-optic detection systems, as well as detection systems using sensor cables. The purpose of the presented systems is to detect and provide early notification to users about potential threats.The paper discusses technical security systems used in the perimeter protection of industrial facilities particularly exposed to the risk of burglary and assault. The reason for protecting these facilities has been the rapid increase in threats and the value of stored property in recent years. Significant development of modern technology and its accessibility (solutions cited in this paper are particularly important) have found practical application in our country, despite the significant costs associated with their implementation.
Perimeter protection (boundary protection) most often constitutes a system aimed at early notification of the presence of an intruder approaching the protected facility. In terms of utility, perimeter protection devices can be divided into:
– mechanical systems, – electronic systems.
In the group of electronic systems, based on physical phenomena, one can list:
– passive infrared systems, – microwave systems, – fiber-optic detection systems, – piezoelectric systems, – electromagnetic motion detection systems, – video detection systems with computer image analysis, – integrated systems, – microphone cables, – other systems.
2. PERIMETER PROTECTION SYSTEMS USING INFRARED DEVICES
The most popular systems of this type are devices that create active infrared barriers with a modulated beam emitted by a transmitter. (…)
