  • Set the minimum plate height for recognition (in pixels)
  • The possible range for the Frames to Detect parameter is from 3 to 100 frames. If a license plate is clearly visible in the frame, it is possible to significantly lower the parameter value to save hardware resources without detection quality loss (e.g. set the value to 5 frames, and set the FPS parameter to 1 in the Hardware tab. The system collects 5 frames within 5 seconds and selects the best one for recognition).
