Multifunctional wireless device for surveillance and protection of persons and method of operation of such device

摘要

The multifunctional wireless surveillance and protection device includes a Personal Unit (1) that sends a signal or data information to the receiver unit (4) when it exceeds the set limits of these sensors or by combining them. The personal unit (1) is activated or deactivated by the Control Unit (2) and can be equipped with a backup signal source. The device further includes a Parallel Unit (3) which monitors the Personal Unit (1), stores information about it and sends a signal or data message to the Receiving Unit or Units (4) when a connection to the Personal Unit (1) or overruns the monitored parameters. The device allows to define geographic areas such that when leaving a predefined area for longer than a specified period, the Parallel Unit (3), independently of the Personal Unit (1) sends a signal or data information to the Receiving Unit (4).
