Introduction 13 IIT Camera System Manual The concept of the IIT Camera is to exploit the retro-reflective properties of t he vehicle license plates. A retro-reflective s urface returns the incomi ng light in the same dire ction it comes fr om.
IIT Camera System Manual 14 Introduction Vehicles are detected from both driving directions (front or rear shot s). The system will only work if the license plate is moving through the retro- reflective sensitive region of the picture area. Other parts of the vehicle being retro-reflective can cause generation of triggers.
Installation Preparation 15 IIT Camera System Manual 2 Preparing for installation 2.1 Preparation for installation As mentioned in the previous sect ion is it essential for the function of the I IT Camera that the license plate moves through the sensitive re gion when the vehicle passes the camera.
IIT Camera System Manual 16 Installation Preparation Figure 6. Typical Over Lane Site Layout Plan The Light Sensor and Flash shown in Fig ure 6 are optional. If over lane mounting is not possible the camera ca n be mounted at the side of the road as close to the road as possible.
