2 Device Installation
2.1 Installation Specifications
2.1.1 Standard Installation
See Figure 2- 1.
Height 1.2 meters
Horizontal distance 4 meters
Snapshot line position
Width ≤3.5 meters
Figure 2- 1
Note:
1. Camera monitoring the scene channel width requirements ≤3.5 m. > 3.5 m, requiring
physical isolation parallel with the camera at 3.5 m spacing, make the passageway to
meet the requirements of ≤3.5 m (Note: Refer to Fout! Verwijzingsbron niet
gevonden.);
2. The camera is mounted on the safety of the island, mounting bracket and channel
boundary spacing should be <0.15 m. > 0.15 m, it will increase the angle of view of
the license plate, the effects of camera algorithm (Note: Refer to Fout!
Verwijzingsbron niet gevonden.).
3. The camera installation height of 1.2 to 1.5 m, 1.2 m recommended;
4. Snapshot camera is mounted on the snapshot line (or coil) pitch (horizontal distance)
from 4 to 6 meters location, recommended 4 m;

5. Scene width adjustment, take a picture of the license plate from 100 to 140 pixels to
identify the best effect.
6. We recommend using a coil to snapshot program.
2.1.2 Before Installation
Many factors affect the camera identification, such as channel width outside the camera
monitoring capabilities, the camera installation point setting unreasonable. These are the
physical factors related vision camera can face up to identify whether the conditions of the
license plate or license plate angle question meets, from a technical level, cannot be
solved. Therefore, in front of the camera installation is a good program, to be
circumvented. The following is a preliminary plan to install cameras Important note:
1. The installation position of the camera in the vehicle into the parking lot should be
planned passage complete turn, straighten the front and then moved back 4 meters
The vehicle has a turning procedure when entering (or exiting) parking lot entrance
channel, when the license plate and the camera is a certain angle, cause the camera
not face license plate or license plate angle is too large, the impact of recognition.
Therefore, the camera should be set up to snapshot the point of complete turn in the
vehicle at the camera front plate. Determine the position of the camera to snapshot
the line, the camera mounting position can be determined by reference to standard
protocols that snapshot the line after 4 meters. See Fout! Verwijzingsbron niet

respond channel do physical isolation, to meet the requirements;

2.2 Coil Cut
2.2.1 Coil Cut Specification
Select coil snapshot scheme system, need to cut coil, see Figure 2- 4.

Figure 2- 4
Note:
1. Coil edge safety distance 30cm;
2. Coil edge depends on lane width;
3. Coil length (vehicle driving direction) 60cm;
4. Coil wind 4 times.
2.2.2 Coil Recommendation
Loop coils are buried beneath the road surface, it is required that it should have good heat
resistance, cold resistance, pull, anti-corrosion performance and flexibility. FVN1.5 ㎡
recommended temperature cables.
2.2.3 Process Requirement
Coil detection system, in order to ensure that the camera is stable coil normal snapshot,
and correct construction process coil is a coil job security. Therefore, make construction
according to process requirements.
Coil cut process is in Figure 2- 5,
