What is the recognition rate?
Recognition rate depends on many factors: ambient lighting, camera setting, exposure and above all camera… It’s crucial to install a proper ANPR camera such our WalzCAM or any similar camera. Intertraff Black Box can read correctly the 98% - 99% of all the license plates passing through the camera field of view.
::
Which is the maximum camera to vehicle plate distance?
It is crucial to set the size of the image correctly, either by changing the lens or by altering the camera aim. The width of a number plate should be approximately 25% of image width at the nominal point where it is to be recognized. With the BlackBox the camera to the vehicle license plate distance should be not higher than 15-20 meters.
