POSSIBLE IR RESTRICTIONS:
The license/number plate is quite close to the frame boundary.
You may notice a vignette effect.
The license/number plate is closer to the centre of the
frame. The plate is illuminated much better.
Pay special attention to IR vignette effect (see illustration on the left) when setting up recognition zone. The closer to the center the more
even illumination is.
Also, in this particular case the real pixel width of the license/number plate is critically small.
The Automatic Gain Control effect will be illustrated in camera exposure settings section.
