70 Mai Dash CamA800S + Rear | 4K UHD Resolution | Built in GPS

Overview

The 70mai Dash Cam A800S + Rear (model A800S with RC06 rear camera) is a budget dual-channel dash cam from 70mai (Xiaomi’s automotive sub-brand), emphasizing true 4K UHD front recording for sharp evidence capture, built-in GPS for location/speed tracking, and ADAS safety alerts. Launched in 2022 with firmware updates through 2025 (latest improving Wi-Fi stability and GPS accuracy), it’s ideal for commuters seeking all-around protection without premium pricing. The Sony STARVIS IMX415 sensor delivers vibrant daytime footage and solid low-light performance via 3D DNR, while the rear provides basic 1080p coverage. At ~$130-160 for the bundle, it’s a steal for 4K dual setup, though the rear cam’s night vision is average and parking mode requires a hardwire kit (~$20). No major hardware changes in 2025, but OTA updates keep it reliable.
