Camera position

In order for the ANPR cameras to read the license plates, they must be positioned correctly.
INCLINATION ON THE HORIZONTAL PLAN
For the reading of the characters to work correctly, it is important that the plate is as horizontal
as possible. Be careful to rotate the camera appropriately so that the angle of the license plate in
the shot does not exceed 5 °
SIZE IN THE PLATE
Adjust the zoom so that the license plate is as large as possible in the frame. For the reading to
take place, the size in the image must be at least 130x70 pixels.
FRONT OR REAR PLATE
You can pick up both the front and rear license plates of the vehicles. If it is possible to choose,
the rear license plate is preferable because the rear lights give less glare.
INCLINATION WITH RESPECT TO THE SENSE OF RUNNING
It is necessary to maintain an angle of about 30 ° with respect to the direction of the vehicles. In
the optimal situation, the 30 ° angle should be maintained both horizontally and vertically. The
30% inclination with respect to the direction of travel is important to avoid the glare of the
headlights in the night shot.
