How does the infrared camera in the 2021 Audi A5 work?

I've heard that the 2021 Audi A5 comes with an infrared camera, but I'm not sure how it works. Can someone explain it to me?

The infrared camera in the 2021 Audi A5 is used for the night vision assistant feature. It detects heat signatures to help you see better in low visibility conditions. In my experience, it works really well on dark roads with no street lights.

The infrared camera uses thermal imaging to detect and display objects that may not be visible to the naked eye, such as animals or pedestrians. My friend has this feature in her Audi A5 and it has definitely helped her avoid accidents at night.
