Abstract
A system for monitoring objects and individuals. In this system, a monitoring station is remotely accessible through a user interface. The interface is adapted to provide a visually cognizable rendering of an area and a tool useful for selecting at least a portion of said area, and to communicate a first request signal to provide location coordinates of a first tracking device. The first tracking device comprises a first transceiver adapted to receive the first request signal, and to transmit a first reply signal that comprises a first identification code. In addition, a second tracking device having a second transceiver is adapted to receive the first reply signal, compare the first identification code to a stored identification code, and communicate to the monitoring station a second reply signal that comprises location coordinates of the first tracking device in part responsive to verification of the first identification code.
