1. A system for monitoring a secured facility that includes at least one door electronically controllable by a control system, the monitoring system comprising:
a plurality of first portable wireless communication devices configured to be individually physically associated with individual members of a first group of persons to be supervised, where at least one of the first portable wireless communication devices is physically associated with a first person that is a member of the first group; at least one second portable wireless communication device configured to be individually physically associated with individual members of a second group of supervising persons when accompanying members of the first group of persons to be supervised; a plurality of wireless detectors placed at predetermined locations of the secured facility and configured to wirelessly communicate with in-range portable devices of said first portable wireless communication devices and the at least one second portable wireless communication device; and a computer system that includes at least one hardware processor, the computer system being configured to:
monitor at least a location the portable devices via the plurality of wireless detectors based on wireless communications with the portable devices;ascertain, based on monitoring portable device locations, when the first person of the first group is in proximity to the at least one electronically controlled door of the secured facility;determine whether the first person, who is a member of the first group, is authorized to use the least one electronically controlled door to access another area of the secured facility based, at least in part, on whether or not at least one person from the second group of persons is also co-located with the first person in proximity to the at least one electronically controlled door of the facility; andresponsive to a determination that the first person is authorized, send an electronic instruction via a control system to permit the at least one electronically controlled door to operate.
