Night Dash Cams: How to Choose for Low-Light Driving

They can record useful night footage, but clarity varies with lighting, speed, exposure, windscreen condition and the camera's image processing.

Not by itself. Sensor size, exposure, lens, bitrate and HDR handling can matter as much as output resolution in low light.

Front road cameras normally use visible light. Infrared is most useful for filming a dark cabin, not for illuminating the road through the windscreen.

Reflective plates can overexpose under headlights. HDR and exposure control may help, but speed and angle can still prevent a readable frame.
