1. A crime prevention system comprising:
a thermal image acquisition device acquiring a thermal image of a balcony;
setting circuitry setting an outside area corresponding to an outside of the balcony and a balcony inside area corresponding to inside of the balcony in the thermal image;
heat source detection circuitry detecting a heat source in the thermal image;
intrusion determination circuitry determining that “there is an intrusion” if a central position of the heat source with the number of pixels and a temperature equal to or greater than thresholds moves from the outside area to the balcony inside area in the thermal image; and
a determination result output device outputting a determination result of the intrusion determination circuitry.
