※ Camera and surrounding area configuration considerations:
3. Auto-focusing should not be enabled for line crossing detection.
4. Avoid scenes with trees or scenes with light changes (such as flashing headlights). The ambient brightness
of the scenes should not be too low.
5. Cameras should be mounted at 9.18 feet (2.8 meters) or higher.
6. Keep the mounting angle of the camera at about 45°.
7. Detected objects should not be less than 1% of the entire image or more than 1/8 of the entire image.
8. Make sure cameras can view objects for at least 2 seconds in the detected area for accurate detection.
9. Adequate light and clear scenery are crucial for line crossing detection.
