  1. Use video cameras with high resolution (720p is recommended).
  2. Frame rate is not less than 24 FPS.
  3. The container speed must meet the camera operation speed. For a better recognition, it is necessary, and it is enough to have 1-2 frames of a container numberThe frame rate from the video camera (FPS) is selected individually and depends on the carriage speed: the faster the carriage goes, the higher the FPS should be, and vice versa. However, the higher the FPS, the greater the CPU load.
  4. It should be possible to set a fixed exposure value (shutter) on a video camera of 1/2000 s or less.
  5. High sensitivity of video cameras (0.01 lx and more).

Licensing requirements based on CPU processing power:

CPU1-core license (FPS)2-core license (FPS)4-core license (FPS)
Intel Core i31-21-41-8
Intel Core i51-21-52-10
Intel Core i71-32-72-14

The optical axis of a video camera must be perpendicular to the plane of the license plate. To simplify the setting, it is recommended to use the varifocal lenses. The focal length variation range should be selected in each case of the system installation.

  1. The position of a carriage or a container in the frame should be strictly horizontal.
  2. Size of the license plate characters in the image must be from 20 to 40 80 pixels, i.e. from 4% of the image height.
  3. The geometric distortion by optics ("barrels" and "pincushions") should be reduced.
