How does the night vision assistant work in the Audi A7?

I'm interested in learning more about the night vision assistant feature in the Audi A7. How does it function and what are the benefits of having this feature?

The night vision assistant uses an infrared camera to detect objects in the dark that may be difficult to see with the naked eye. It can detect pedestrians and animals up to 300 feet away, providing an early warning for potential hazards.

Having the night vision assistant can greatly improve your safety while driving at night. The system can automatically apply the brakes if it senses an imminent collision with a pedestrian or animal.
