The A800S pushes the limits of image quality with the industry's highest resolution standard—up to 4K Ultra High Definition of 3840x2160—delivering incredibly clear frames when you are on a road trip. The A800S uses seven layers of high-quality glass lenses with an F1.8 aperture and a Sony IMX415 sensor that processes frames faster to deliver images with better clarity and vividness. Compatible with the RC06 rear camera, the A800S can achieve dual-channel recording, providing all-around protection so you can drive with peace of mind. The A800S is also compatible with the FC02 interior dash cam, giving you a full HD view of your cabin. With the lane-departure warning system and the forward-collision warning system, the ADAS detects your surroundings and uses voice alerts to warn you of safety concerns.
