CRIME PREVENTION SYSTEM
Document Type and Number:
Japanese Patent JP3812572
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a crime prevention system by which the action of an invader is effectively inhibited without causing annoyance or suffering on a close neighborhood or a living environment.
SOLUTION: A controller 9 transmits a lightning control signal to a lighting fixture 4 at an entrance when a shading section 2 is in a shading state and a detection signal informing the detection of the invader is received from an unusual state detection section 8, and transmits a light-out control signal after elapsing several seconds. After the eyes of the invader invaded an entrance area EA are adapted to a bright environment for several seconds, the eyes of the invader are suddenly exposed to a dark environment. Thus, an environment requiring dark adaptation to the invader in the entrance area EA is created to temporarily take away the sight of the invader, thereby inhibiting the action of the invader.
