Intrusion detection system
Burglary and assault signaling systems or intrusion detection systems (IDS) are widely used signaling systems in both commercial and private facilities. This protection protects the object against the intrusion of unauthorized persons, as well as against vandalism. In addition, the systems perform control functions, thanks to which their operation can be flexibly adapted to the needs and preferences of the user and the specifics of the protected object.
Intrusion detection systems can be implemented in both wired and wireless technology, and can also be equipped with the function of mobile control and system control from the level of a dedicated application for smartphones or tablets.
Burglary and assault signaling systems can protect one or several zones of the object, and can also be used to protect the interior of a building as well as external zones lying in the open area adjacent to the protected building.
Elements of the burglary and assault signaling system
Burglary and assault signaling systems consist of detection, signaling and executive devices. Among them, the most important elements are the control panel, detectors and control modules.
Central control panel
The intrusion detection system central collects data collected by detectors, analyzes them and, based on processed information, controls the operation of control and executive elements. The control panel is also responsible for the alarm and notification functions. The operation of the intrusion alarm system control panel is based on the previous configuration of how the system works. The system control panel is selected based on the number of zones and outputs, the size of the installation, the expected functionality, as well as the required degree of security of the facility.
There are many detectors used in intrusion detection systems, among which the most common are: infrared detectors, microwave detectors, reed switches, vibration detectors and bruises, PIR detectors and dual detectors.
Active infrared detectors
Infrared detectors can be used both indoors and outdoors. They work by creating an invisible infrared barrier between the transmitter and receiver. Violation of the barrier will trigger an alarm.
Passive infrared detectors (PIR)
These are passive infrared detectors used as motion detectors. Their operation boils down to detecting changes in thermal radiation in the detector's field of operation. Detection of warmer elements that stand out from the heat emitted by the background causes the detector to be excited.
Microwave detectors (MW)
Microwave detectors detect movement in the room based on the emission and reception of microwave waves. If a given object violates moving waves, the detector will activate the intrusion detection system. The advantage of microwave detectors is that they are insensitive to temperature changes.
Dual detectors combine two types of detection elements - e.g. microwave detectors and passive infrared detectors. These detectors allow for precise detection of threats and maintain high resistance to false alarms.
Reed switch contacts are also magnetic detectors; openings that detect the opening of windows or doors. If they are opened, the electromagnetic field disappears and the alarm goes on.
Breakage detectors react to the acustic emission associated with breaking glass and detect vibrations occuring during physical violations of the object during drilling, impacting or balancing.
The advantages of IDS:
- closing selected zones,
- automation of the area process,
- security of surveillance lines,
- cooperation with other systems.
