How does in-Camera Night Vision work in the Audi A8?

I am impressed with the in-camera night vision feature in the Audi A8, but I am unsure of how it actually works. Can someone explain it to me in more detail and how it differs from traditional night vision systems?

The in-camera night vision in the Audi A8 uses a thermal imaging camera to detect and display objects, pedestrians, and animals up to 300 meters ahead of the vehicle. This system works by capturing infrared radiation emitted by objects and using it to create a real-time image of the environment.

Unlike traditional night vision systems, the in-camera night vision in the Audi A8 does not rely on an infrared light source to illuminate the road. Instead, it uses the natural infrared radiation emitted by objects to create a clear image, providing a more realistic and accurate view of the surroundings.
