Overexposure During the Day

Because the sun is hitting the license plate, it is directly reflected off the camera lens, causing the image to be overexposed.

There are several general strategies:

• 

  Try to avoid east-west direction in installation

• 

  Do not install the camera in the direction where the sun is just reflecting back. It is recommended to install the camera on the B side of the road, not the A side

• 

  Use automatic aperture lens

• 

  Enable WDR

Overexposure At Night

There are several kinds of common overexposure issues in the evening. Here are some general recommendations if you encounter issues with Overexposed Picture using the camera:

• The influence of the vehicle headlights, resulting in the inability to see the license plate

• 

  Enable WDR

• 

  Turn on the supplementary light of the camera

• Other vehicles have their license plates irradiated, resulting in overexposure

• • Avoid headlight reflection angles
  • Try to select parallel lanes for installation

• The camera's own light is too bright or the Angle is affected

• 

  Reduce the brightness level of the camera light itself

• 

  Reduce the number of lights on

• 

  Decrease the shutter and gain parameter values appropriately (generally default values are recommended)
