FIELD: systems for observation and remote alarm signaling. ^ SUBSTANCE: the system has a fixed module placed in the area within which the person can move, and a personal component of a bracelet fastened to the person subjected to restriction of motion. The fixed module is adapted for establishment of an electromagnetic communication with the personal component and communication via a telephone line with the operation center. The fixed module is equipped with a central processor linked with a finger print reader and a radio-receiving device adapted for interaction with a similar radioreceiving device built in the personal component together with the central processor, which controls its operation. At a detection of any interruption and/or anomalies of communication between the fixed module and the personal component an alarm signal is sent to the operation center. ^ EFFECT: enhanced reliability of detection of the presence of the detained person in the building and alarm signaling. ^ 6 dwg |
