All rights reserved. Page 2 To increase the licence plate recognition accuracy, you need to install the LPR camera in the proper way to capture the qualified plate images. When you install the LPR camera, there are certain criteria to meet, including the plate size, the lighting condition and the angle of the camera. In this document, we provide the qualified image examples, and the unqualified image examples, which are generated when the LPR camera is set in an improper way.

Page 7 The plate is in shadow: Example Try to: Avoid placing the camera where it can be subjected to direct sunlight or reflections.
Visible shadow edges in the camera view may degrade the recognition accuracy. Ensure to install the camera to meet the following conditions. In this way, the height of the captured plate characters would approximately fall between 30 and 35 pixels.
To avoid capturing unnecessary contents in the image, the camera should be installed in a higher position to capture the front part of the vehicle only. It is normally used on freeway recognition where the vehicle speed is high. Page 11 www. Page 12 9F, No.
