This system is also one of the subsets of electronic protection. By using the available equipment, you can control the entry and exit of personnel using personnel cards or fingerprint systems to manage this issue. Also, with the help of existing software, it is possible to determine the level of access in different layers for personnel.

The Intrusion Detection System uses real separators (fences, barbed wire, and walls) and virtual separators (camera image processing) to prevent intruders from entering. In general, the use of virtual fences has a relative advantage over older separators in terms of cost and points, although they are not a good alternative to older separators complement them. Virtual fencing is made possible by the use of camera image processing, and several brands have equipped their cameras with image processing (analytic). By processing images, the system is notified of people entering the predetermined area and displays it as an alarm.

Fire alarm systems are divided into two categories. Analog and Addressable. Analog systems, which have older knowledge, use several zones supported by the central device to communicate with detection sensors and alarms and flashers. The addressable system uses a more limited number of zones and communicates with more sensors with the help of two-wire communication (RS485). And its advantages over analog systems include increasing the number of connected sensors and accurate information about the activation of sensors based on the exact zone and position of the detector, as well as reducing the cost of infrastructure required. Of course, the new generation of fire alarm systems are completely wireless, which has these advantages over older systems: The use of wireless communication, Internet connection, connection places with other network-based systems, as well as the lack of cable use, makes it possible to install these systems anywhere.
