3.2Determining the Angle

The maximum mounting angle of the license plate camera to the car is 40° for speeds up to 160 km/h (100 mph), both horizontally and vertically. This angle limits the amount of skew of the letters on the number plate. If the letters are skewed too much they will start to become unrecognizable and will reduce automatic software recognition rates.

For maximum performance ensure the mounting angle is as narrow as possible. To capture vehicle speeds up to 225 km/h (140 mph) the horizontal and vertical mounting angle should be less than 30°.
