Unlike conventional dual-channel dash cams, the A229 Ultra-W records in full 4K Ultra HD with both cameras, while its waterproof rear camera can also be mounted on the exterior of the vehicle. Thanks to Sony STARVIS 2 sensors, HDR technology, and the F1.5 aperture, license plates and important details remain clearly visible during the day, at night, and even in rain or snow.
