Abstract: The objective of this paper is to solve the “simplicity” problem that can be reduced to the existing CPTED effect by developing (and improving) a CPTED equipment and maximize the effect. We have developed image project and voice guidance system for crime prevention based on CPTED strategy, it uses a sensor (P-IR or Microwave) to detect the human movement and projects the image on the ground and simultaneously playback the voice. It also used high brightness 20W LED and was developed to be able to attach it to facilities such as CCTV pole, street lamp by developing separate bracket. The developed equipment is a combination of an image projection device and a voice guidance system, and when the motion sensor is detected movement, an image of a separately produced image glass is projected on the ground and CPTED alters is broadcasted. Since the device usually installs at a wide variety of location, we divided into the short-distance projection and the long-distance projection, and the voice guidance system is basically powered and playback by the response of the sensor, but it is also can operate on a separately developed scheduling basis to improve the independence of the apparatus. This is because the power can be supplied from a separate port provided in the CPTED alters voice guidance system for crime prevention. Therefore, it has versatility to use both the functions of the scheduling base and the functions of the sensor base, so it is excellent in utilization according to the situation, and the image glass of the image projection device can be changed. In addition, it can be used for various purposes by replacing the sensor, it is possible to construct a line-up (e.g., smoking detection) with various products, which can actively respond to various demands of the market.
