1. A method of operating an electronic house arrest monitoring (EHAM) system so as to automatically assess a prescribed fee to a responsible person or entity that has consented or been assigned responsibility to pay monitoring fees for an individual whose presence or absence at a monitoring location is being monitored by the electronic house arrest monitoring system, said method comprising the steps of:

  • (a) installing a field monitoring device at the monitoring location and coupling an electronic detection circuit to the individual to be monitored at the monitoring location;

    (b) detecting whether a prescribed event occurs during a first predetermined period of time;

    (c) generating a detection signal within the field monitoring device in the event the prescribed event is detected as occurring during the first predetermined period of time;

    (d) accessing a communications network with the field monitoring device using a fee-based communications mode that has a prescribed fee associated therewith that is automatically assessed to the responsible person or entity when the communications network is accessed using the fee-based communications mode; and

    (e) transmitting information indicating whether the prescribed event was detected in step (b) from the field monitoring device to a central monitoring system through the communications network, whereby the central monitoring system receives information indicating whether the prescribed event occurred during the first predetermined period of time.
