70mai Dash Cam 4K A800SE + Rear Camera 70mai RC22

About the 70mai Dash Cam 4K A800SE with RC22 Rear Camera

Record every trip with true 4K video at 30 fps on the front and Full HD 1080p on the back , combining hardware HDR , F1.55 optics , and a proprietary algorithm to balance light and shadows. The system is powered by a supercapacitor —reliable from -10°C to 60°C—and adds Wi-Fi 6 and multi-constellation GPS for fast downloads and recording of route, speed, and coordinates. 

Dual recording: 4K + 1080p

The front camera maintains 3840 × 2160 px resolution even in dual mode, while the RC22 rear camera covers 130° at 1080p, ensuring front impact resistance and rear reach without loss of detail.

Enhanced night vision

The large F1.55 aperture and Super Night Vision  software increase light capture by up to 78% compared to F2.0 lenses, reducing noise and highlighting license plates in night scenes.

24/7 protection with extended buffer.

In the parking lot (requires hardwire kit), a G-Sensor activates 30-second clips and retains up to 3 minutes of prior data , preserving the context before and after any impact. 

Connectivity and storage

2.4 GHz Wi-Fi 6 speeds up previewing and downloading in the 70mai app; USB mode makes copying easy without removing the microSD card. Supports U3 cards from 32 GB to 512 GB and loop recording.

Five-mode ADAS

It includes alerts for frontal collision, lane departure, forward collision, pedestrians, and cyclists , with voice warnings that anticipate risks and reinforce active safety.

Our expert’s opinion

The dual set of the 70mai Dash Cam 4K A800SE extends the coverage of the “front-only” model without sacrificing 4K definition, placing it above alternatives such as the Viofo A229 Duo (4K + 2K) or the Nextbase 522GW + Rear, which lack a 3-minute buffer and the robust supercapacitor. Compared to the previous A800S, it adds Wi-Fi 6 and hardware HDR, while maintaining its competitive price-quality ratio . For drivers seeking comprehensive coverage, reliable night vision, and discreet installation, the A800SE Duo offers a balance that’s hard to match, with the option to further enhance protection through a hardwire kit and advanced surveillance modes.
