<p>A method, apparatus, and system for remotely monitoring the location of a monitoree within a monitored area. The method includes the steps of: securing to a monitoree by a harness a closeable housing containing a transmitter for transmitting an identification signal for identifying the transmitter; locating within a monitored area a receiver for receiving the identification signal; measuring the signal strength of the identification signal received at the receiver; and comparing the signal strength to a predetermined signal strength threshold to determine whether the transmitter is located within the monitored area.</p> |
