Recommended settings for different architectures of the cameras

Positioning the Vehicle:

- Ensure the vehicle is within the region of interest so that the license plate occupies enough area for detection and recognition.

License Plate Size:

- Access the camera's system settings and navigate to the Orientation menu.

- Enable the pixel counter and verify that a single-row license plate is at least 130 pixels wide, while a two-row license plate should be at least 70 pixels wide.

- Adjust the camera's position if necessary to meet these size requirements.

Autofocus:

- Set the autofocus area on the license plate and click Autofocus. 

- If the license plate is not in focus, fine-tune using the manual focus.

Wide Dynamic Range (WDR):

- Disable WDR to prevent overexposure in high-contrast scenes.

Aperture:

- Turn off the Lock Aperture setting to allow the iris to operate in automatic mode, especially useful when the vehicle faces direct sunlight.

IR-Cut Filter:

- Set the IR-Cut Filter to "Auto" so the camera can automatically adjust based on lighting conditions.

Recommended Settings for Different Processor Architectures

ARTPEC-7:

- Shutter Speed:1/500

- Max Gain: 24

- Contrast: 50

- Local Contrast: 20

ARTPEC-8:

- Shutter Speed: 1/500

- Max Gain: 20

- Contrast: 65

- Local Contrast: 65

- Tone Mapping: 20

These settings generally provide stable performance without needing further adjustments.
However, if they do not meet the client’s specific needs, additional adjustments may be required based on environmental factors, lighting conditions, etc.

Explanation of Key Settings:

Local Contrast:

- Reduces noise during nighttime while maintaining visibility of license plates.
Adjust higher for better night visibility, but note that it may increase noise levels.

Max Shutter:

- Controls the shutter speed of the camera lens to optimize image sharpness and clarity.

Max Gain:

- Helps reduce motion blur and control noise levels. If license plates are overexposed, decrease this setting.
