70mai Dash Cam 4K A810

70mai is one of the world's largest dash cam brands (backed by Xiaomi), and the A810 shows why. 4K front recording with an optional 1080p rear camera, ADAS (Advanced Driver Assistance Systems) with forward collision and lane departure warnings, and built-in GPS — all for $120. The Sony STARVIS 2 sensor handles night recording well, and the companion app is one of the better dash cam apps available. 70mai has sold millions of dash cams globally, and the reliability data backs it up. Car and Driver highlighted 70mai as a strong value alternative to pricier options.
