70mai 4K A800S Dash Cam Car DVR 2021 Smart DVR Built-in GPS with ADAS UHD Image SONY IMX415 140FOV 24H Parking Monitor

Dual-Channel with Outstanding Image Quality

The A800S uses 7 layers of high quality glass lenses with F1.8 aperture and Sony IMX415 Sensor that process frames to deliver images with better clarity and vividness.

Super High Resolution of 4K UHD

The A800S pushes the limits of image quality with industry's highest resolution standard–up to 4K Ultra High Definition of 3840*2160P–delivering incredibly clear frames when you are on a road trip.

Powerful Night Vision

The A800S uses an F1.8 aperture lens with 3D DNR (Dynamic Noise Reduction) technology and smart AI algorithm to reduce image noise. This gives the A800S outstanding low-light performance, delivering clear images during any time of day or under certain weather conditions.

Advanced Driver-Assistance Systems (ADAS)

The ADAS will detects your surroundings and uses voice alerts to warn you of safety problems.

Built-in GPS

Monitors and displays real-time trip data including time, speed(km/h,mph), and coordinates. Tracks the exact location of an accident if one should occur, crucial for roadside assistance and insurance claims.

24-Hour Parking Surveillance

Keep monitoring when you asre away. The built-in G-sensor can detect sudden shakes or collisions while your car is stationary, and will automatically start recording to capture any potential incidents. If an emergency video is recorded, the dash cam will notify you through voice alert once it's turned back on.

In-app Control & Footage Sharing

The 70mai App supports both iOS & Android systems,allowing you to view and download HD videos inreal time through the dash cam's Wi-Fi. It also locks emergency videos to the “Event File” to prevent an overwrite.

Loop Recording

The A800S uses loop recording to continuously overwrite loder footage so your memory card does not run out of space. You can check and download recorded videos in the 70mai App.
