How does the Night Vision feature work in the Audi A8?

I want to learn more about the Night Vision feature in the Audi A8 and how it detects obstacles in low light conditions.

The Night Vision feature in the Audi A8 uses thermal imaging technology to detect heat signatures and display them on the Audi virtual cockpit.

In low light conditions, the Night Vision feature in the Audi A8 can detect pedestrians, animals, and other vehicles up to 300 meters ahead and display them as yellow or red outlines.

The Night Vision feature in the Audi A8 can also detect and highlight road signs and lane markings to help the driver stay on the correct path in dark or foggy conditions.
