PROBLEM TO BE SOLVED: To provide a crime-prevention system for using a light source for both threatening and illumination. SOLUTION: A sensor light 1 is provided with: a call part 12 for call; a human body detection part 13 for detecting a human body within a prescribed detection range; an illumination part 15 for illuminating the detection range; and a radio reading part 14 for reading identification information from an IC tag held by the human body who enters the detection range. A master unit 2 is provided with: a call part 22 for call and a storage part 26 for storing the identification information. After the human body is detected by the human body detection part 13, when any of the identification information stored in the storage part 26 is read by the radio reading part 14 within a prescribed reading period, the illumination part 15 is turned on, and when any of the identification information stored in the storage part 26 is not read by a radio reading part 14, the illumination part 15 is turned on and an alarm sound is issued by the call parts 12 and 22.
