1. An electronic monitoring system for monitoring compliance of a protective order, said protective order being imposed to restrain a first person from coming near a second person, said electronic monitoring system comprising:

  • a transmitter tag, said transmitter tag including transmitting means for periodically transmitting a first identification signal over a first range, and means for securely attaching said transmitter tag to said first person, whereby the first identification signal generated by the transmitter tag uniquely identifies said first person to whom the transmitter tag is attached;

    a monitoring device located proximate said second person, said monitoring device including;

    receiving means for receiving said first identification signal,verification means for verifying that said first identification signal comprises the identification signal that is transmitted by the transmitter tag attached to said first person, andmeans responsive to said verification means for promptly establishing a telecommunicative link with a central processing unit (CPU) located at a central monitoring location remote from said monitoring device, and for sending to said CPU a notifying signal through said established telecommunicative link indicating that said first identification signal has been received and verified by said monitoring device, whereby said CPU is put on notice that a distance of said first range is all that separates the transmitter tag, and hence the first person to whom the transmitter tag is attached, from said monitoring device, and hence that said first person has likely violated said protective order; and

    a sensor positioned to sense the presence of an individual who has entered a zone protected by said protective order, said sensor being activated by said verification means, said sensor generating a sensor signal that is coupled to said monitoring device;

    whereby a violation of said protective order by said first person may be confirmed through the receipt of said first identification signal and the generation of said sensor signal.
