LPR Camera distance

The distance between the camera and the subject is important for two reasons:

LPR ZKTeco distance 30 pixels height ZKTeco LPR camera

Dimension of the characters
The dimension of the characters of the number plate must be 30 pixels high or higher

IR Lights
The illumination power of the IR lights is affected by the distance; the near the better.

Place the camera as near as possible (between the recommendation)

LPR Camera angle

The recognition of the plate is affected by both vertical and horizontal angle. Lane straight as possible: Curve installation will reduce the aqccuracy of the camera.

Vertical Horizontal

The angle of inclination of the vehicle's number plate must not exceed 5°. Position the camera with the smallest possible tilt angle.
