FIELD: information technology.
SUBSTANCE: method consists in analytical calculation of the direction of movement of an intruder based on the a priori known speed of the intruder and the recorded time delay in arrival of alarm signals from three detachable linear parts deployed on an area as a single signalling secure boundary with given geometric dimensions. The method includes a preparatory step for deploying linear parts of detachable means of detection with orientation thereof on the area and relative each other on a set scheme and practical determination of the probable speed of the intruder through the secure boundary and the main step which begins from the moment the intruder crosses the secure boundary. During the main step, time intervals between alarm signals when the linear parts are broken are recorded. Based on said time intervals and the a priori known speed of the intruder, the direction of movement of the intruder is calculated and indicated on the scheme.
EFFECT: less time spent on determining the direction of movement of an intruder, remote, automatic and real-time determination of the direction of movement of the intruder.
