CRIME-PREVENTION SYSTEM AND CRIME-PREVENTION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a crime-prevention system and a crime-prevention program for more easily monitoring a burglary operation without worrying about the dead angle of a camera.

SOLUTION: This crime-prevention system includes: a plurality of radio communication terminal devices 2 which have acceleration sensors (vibration detection parts) 5 each arranged at a branch of a tree for detecting the vibration quantity of the branch and communication parts 6 having relay functions for configuring an ad hoc network N with each other for transmitting/receiving the vibration quantity; and a determination device 3 which has an arithmetic part 7 for processing the received vibration quantity and a determination part 8 for determining whether the occurrence of acceleration generated at the branch is caused by an artificial operation or a natural state by comparing the scale of the worked vibration quantity with that of a predetermined threshold relating to this vibration quantity.
