70mai A810 4K Dash Cam with Night Vision

The 70mai A810 is a dual-channel 4K dash cam built around a Sony STARVIS 2 IMX678 sensor, the same imaging sensor family used in several higher-end dash cams on this list. It records the front channel at up to 3840×2160 (4K) with a 150° field of view and an f/1.8 aperture, paired with a 1080p HDR rear camera, and supports 60fps, 30fps, and 25fps frame rates depending on mode.
