What does night vision without light mean?
2 Answers
Night vision without light refers to a feature of a dash cam that allows it to clearly capture objects within the lens even in complete darkness. The functions of a dash cam include: 1. Recording various status information of the vehicle's movement and the driver's operations, as well as the vehicle's location and travel route; 2. Automatically issuing continuous alarm prompts when the driver is fatigued but hasn't stopped to rest, and back-end monitoring departments can also contact the driver for a break; 3. Recording the vehicle's driving status, and by extracting the stored data from the dash cam, assisting in determining the responsibility for traffic accidents, thereby making the determination of accident liability more scientific.
Last time I chatted with a friend about night vision systems, I finally understood how no-light night vision works. Simply put, in complete darkness without streetlights, there are several infrared headlights hidden in the front of the car that project special light into dark areas. This light is invisible to our naked eyes, but the camera mounted at the top of the windshield can capture it. The dashboard or central display screen acts like a night vision screen, turning pedestrians and animals in the dark into bright white images, resembling old-fashioned surveillance footage. The night vision system in the Mercedes-Benz S-Class is particularly reliable—on winter nights driving on rural roads, it can clearly show the outlines of pedestrians over a hundred meters away, two to three times farther than the range of the factory headlights. However, using this feature on clear nights can be distracting, so it's best to turn it off manually.
