FIELD: physics.
SUBSTANCE: invention uses a hybrid distributed sensing element consisting of two types of cable, a metallized fiber optic cable located inside the triboelectric cable, and acting as its central mobile core. Moreover, taking into account the degree of attenuation of the electrical and optical signals, the long OFC covers the entire perimeter of the protected object, and short segments of the TC are located only in the most critical areas. The place of unauthorized penetration of the intruder is determined by the device by the presence of a simultaneous triboelectric and optical signals or by the arrival of an optical signal only to the console.
EFFECT: increasing the functional reliability and reliability of information on unauthorized access to the protected area with simultaneous identification of an unauthorized penetration zone.
