The 70mai Dash Cam Front and Rear A810 is a budget-friendly dual-channel (front + rear) dash cam from 70mai (a Xiaomi-backed brand), launched in late 2023 and still a top pick in 2025 for its stellar 4K front recording and AI features. It excels in capturing crisp evidence for accidents or insurance claims, with HDR night vision and ADAS alerts for safer driving. The front camera shines with Sony Starvis 2 tech for vibrant, detailed footage, while the rear adds 1080p coverage—though it lags in low light. At under $200 for the bundle, it’s a value champ for daily commuters or families, but the app can feel clunky, and parking mode needs hardwiring. No major 2025 updates, but firmware patches have improved stability.
Key Specifications

- Video Quality: Front captures are “excellent” with rich colors, sharp details (zoomable plates up to 50ft), and quick light adjustments—outpacing some pricier rivals like Cobra SC 400D. Rear is “livable” for coverage but needs post-processing for clarity; drops to 25fps in dual mode (from 30fps single). Overall, great for evidence in varied weather.
- ADAS & AI: Lane departure/forward collision warnings, AI motion detection for parking surveillance (alerts on human activity/impacts). Smart features like route maps and speed logs via app.
- App & Usability: 70mai app (iOS/Android) for live view, downloads, sharing—Wi-Fi connects fast, but UI can lag. Voice commands (“Take photo”) add hands-free ease. Parking mode (with hardwire) offers 24/7 monitoring/time-lapse, but supercapacitor limits unplugged use.
