Installation and Initial Configuration
Physical Installation
This section describes the physical installation of a single lane C5 system.
Installation Location Considerations
You can install C5 so that it will capture an image of either the front or rear of a vehicle.
The probable reasons for a rear installation include:
♦
Front installation is not possible due to traffic lane limitations. For example, the front
area is located in a public area in which no installation is permitted.
♦
Vehicles carry only rear license plates. This is true for most of the United States.
♦
Additional installation of a secondary camera in order to increase the recognition
coverage. In this case, two cameras are installed per lane. One is a C5, designated
the primary. The second camera has no internal CPU and is designated the
secondary. Typically, the secondary camera is the SCH3-IR for reflective plates and
the SCH3-Yellow for non reflective plates.
The dual-camera option (primary and secondary in dual enclosure) is not currently
supported.
Step 1 – Determining C5 Location
The location of C5 depends on whether you are installing it to capture an image of the
front of a vehicle or its rear.
Determining Front Installation Distances
♦
Install C5 2.5 meters from the barrier, in the direction of traffic, at the side of the lane
as near as possible to the lane. For non-reflective plates and USA size plates, install
C5 2 meters from the barrier (
B
in Figure 4).
♦
The distance from C5 to the license plate of the car should be 7.5 meters for a plate
length of 50 cm, or 6.5 meters for a plate length of 30 cm (
A
in Figure 4).
WARNING:
A possible problem is that the barrier blocks the effective recognition
view zone, which is the area from the start of detection. In most gates, the
barrier’s height is 0.80 to 1.20 meters, so no blocking occurs. However, this
should be tested and avoided if necessary
