摘要
The surveillance and remote alarm system for persons subject to limitation of freedom of movement comprises a fixed unit placed in the area within which the person can move and a personal bracelet element attached to the person subject to limitation of freedom of movement. The fixed unit is arranged to establish an electromagnetic connection with the personal element and a connection via a telephone line to an operations centre. The fixed unit is equipped with a control unit CPU (7) associated with a fingerprint reader (10) and a radio receiver (9) arranged to interact with a similar radio transmitter (4) fitted in the personal element together with a CPU that controls its operation. Means are provided, under the control of the CPUs, to detect any interruption and/or anomalies in the connection between the fixed unit and the personal element and to send an alarm to the operations centre; methods (5) of detection of tampering or sabotage are also fitted.
