FIELD: monitoring systems.
SUBSTANCE: invention relates to security monitoring methods of area. Method consists in deploying in place of convergence of three roads in one of two detection means (DM) according to a scheme providing separation of useful signal with different depth and modulation sign in receiver (PRM) of each facility when crossing security zone (SZ) by intruder and application of corresponding algorithm, which determines movement of intruder on each of four roads convergence point by number of DM, issued alarm signal, indicating unit (units) of threshold, which registered useful signal, and by obtained combination of two roads, on which intruder was detected.
EFFECT: enabling detection of all twelve directions of intruder displacement through the point of convergence of three roads into one.
