METHOD OF PROTECTING CONTROLLED ZONES AND SECURITY ALARM SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2024 - IPC G08B21/22 

FIELD: security alarm systems.

SUBSTANCE: method of protecting monitored areas is implemented by a security alarm system comprising a plurality of frequency-modulated continuous radiation radar sensors, configured to scan space in front of them at an angle of at least 120° and operate in range of 5.8–24 GHz, connected through the controller to the security post, a plurality of radio frequency scanners configured to measure the power of the radio signal coming to them, a plurality of digital radio labels with identification data recorded on them, made with possibility of their placement on employees located on the territory of the facility, and possibility of sending data pre-registered on them to said radio-frequency scanners, wherein said radar motion sensors and radio frequency scanners are connected through a controller with a communication module to a central observation station, which includes a data module, an incoming signal processing module, response signal processing module and user interface.

EFFECT: high accuracy of detecting an intruder in controlled areas of a secure facility.
