IIT Camera System Manual
16 Installation Preparation
Figure 6. Typical Over Lane Site Layout Plan
The Light Sensor and Flash shown in Figure 6 are optional.
If over lane mounting is not possible the camera can be mounted at the side of the road as close to
the road as possible.
2.2 Performance of Trigger and Light Sensor function
As mentioned in section 2.1.1 the performance of the camera is dependent on respecting
installation parameters. These performance conditions have influence on both the trigger and the
light sensor function.
Various weather caused conditions may also influence the performance. A wet license plate has less
retro-reflectance than a dry one and the same applies if it is covered with dirt or snow. Some
license plates have reduced retro-reflectance due to wear and tear.
