FIELD: information technology.
SUBSTANCE: method consists in analytical calculation of the point of intrusion based on the recorded time delay in arrival of alarm signals from three detachable linear parts deployed on an area as a single 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 the main step which begins from the moment an intruder crosses the secure boundary. During the main step, time intervals between alarm signals when the linear parts are broken are recorded, and the point of intrusion is calculated with indication thereof on the scheme based on relationships between the measured time intervals and known geometric dimensions of the secure boundary.
EFFECT: high accuracy of determining the point of intrusion with detachable means of detection in real time, remotely and automatically.
