information, a group setting unit for setting a group of monitor
terminals of persons to be monitored who are allowed to be mutually
grouped, and a first transmitting unit for transmitting the obtained
position information and group setting information to the information
managing apparatus. The information managing apparatus has a first
receiving unit for receiving the position information and the group
setting information, a management information storing unit for storing
attribute information on the person to be monitored and a condition for
determining a monitor level of the person to be monitored, a mutual
distance recognizing unit for calculating a distance between the monitor
terminals from the position information, and a monitor level determining
unit for determining the present monitor level based on the calculated
distance, the attribute information, and the monitor level determination
condition.
