Dash cams are designed to work in low light and at night. Some dash cams come with night vision capabilities, which use infrared light to illuminate the area in front of the camera. Others may have a wider aperture to allow more light to enter the lens, or use other advanced features to enhance image quality in low light conditions.
It is important to note that the quality of footage recorded at night may not be as good as during the day, as there is less light available for the camera to work with. Additionally, glare from headlights and streetlights can affect the clarity of the footage. But, dashboard cams can still provide valuable footage for documenting accidents or incidents that occur at night.
