Image Quality Issues

  • Poor Lighting: Insufficient or uneven lighting can make it difficult for the system to accurately identify characters on the license plate.
  • Obstructed Plates: Dirt, mud, snow, or other obstructions on the license plate can hinder recognition.
  • Camera Angle and Positioning: Incorrect camera angles or positioning can lead to blurry or distorted images of the license plate.

​
License Plate Design and Format Variations:

  • Non-Uniformity: Different regions and countries have varying license plate designs, fonts, and formats, which can pose challenges for the recognition system.
  • Tampering and Alterations: Some individuals may try to alter or obscure their license plates to avoid detection.

​
RFID

Vehicles with metalized windshields or those containing chromium oxide can pose challenges for RFID readers. This is because these materials can interfere with the radio waves used by RFID systems, making it difficult to read the tags attached to these vehicles.

Other models may also have headlamp installations that can interfere with the rfid readers.
