How to enhance license plate recognition

To better recognize the license plate of a car passing by the camera, you can apply and adjust a number of things.
One option is to use the pixel counter in your camera to set the optimal pixel resolution:
1. Go to Settings > System > Orientation and click
2. Adjust the size and placement of the rectangle in the camera's live view around the area of interest, for example
where the license plates of passing cars are expected to appear. You can then see the number of pixels represented by
the sides of the rectangle.
Note
You can use an object of a known size in the view as a reference to decide how much resolution is needed for recognition.
In addition, you can try to adjust the following to optimize license plate recognition:
• Shutter speed
• Gain
• Zoom

How to monitor long and narrow areas

Use corridor format to better utilize the full field of view in a long and narrow area, for example a staircase, hallway, road, or tunnel.
