ABSTRACT:
A personal security system including features for monitoring guard tours and other surveillance by security personnel. The security system includes a plurality of hand-portable transmitters, a plurality of fixed receivers and a control station. The transmitters are actuated to emit radio frequency signals including a class code that identifies first and second sets of the transmitters. The first set is assigned to security personnel and the second set to system subscribers. The receivers decode the signals from the transmitters and provide an output representing the receiver and the received class code. The control station identifies the location of the transmission using information from the receiver output, and records the time of the transmission. If the class code represents a security-assigned transmitter, the control station reports the information as a security function, such as a guard tour. If the class code represents a subscriber, the control station initiates actions appropriate for a subscriber transmission.
