PROBLEM TO BE SOLVED: To provide a telephone system capable of detecting a moving route of an invader, without using a monitoring camera under a crime prevention mode. SOLUTION: Each of a plurality of telephone terminals constituting a telephone system includes a human sensitive sensor. When an invader is detected by a human sensitive sensor in a state under a crime prevention mode, a telephone terminal sends to a control apparatus sensor detection information including at least identification information of the telephone terminal's own. The control apparatus stores map information in which an area indicating the detection area by the human sensitive sensor, is made corresponding to identification information of the telephone terminal having the relevant human sensitive sensor. The control apparatus recognizes a position, at which the invader is detected, and an invader detection time from the received sensor detection information. A moving route of the invader is detected from the detected invader positions and the invader detection times. COPYRIGHT: (C)2011,JPO&INPIT |
