All dash cams record at night, or whenever light level gets low (ie. in the tunnel or underground parking). Of course, the quality of the recording varies from brands to models, but you’ll see more or less the same technical terms: WDR, HDR and Super Night Vision. What do they mean?
Say, you’re driving on an overcast day with little sun and few shadows, and since they won’t be many areas of deep dark or extreme bright spots, the range will be fairly low. But on a sunny day, you will see more extreme sunny spots as well as distinct shadows.
WDR, or wide dynamic range, means that the camera will auto-adjust to accommodate the difference between the brightest and the darkest areas so that the particularly bright and the particularly dark will be adjusted so that they can be seen clearly at the same time.
HDR, or high dynamic range, means that the camera will auto-adjust the images by adding more dynamic illumination rendering, so that the photos are not overexposed or underexposed - and what you’re left with is an image that is not too bright or dark.
Night vision is a term used to describe the dash cam’s recording capabilities under low light conditions, which is made possible by extremely high light-sensitivity Sony image sensors.
