Best Overall: 70mai A810 (¥399)

The 70mai A810 is the current benchmark for dash cams in China. The Sony IMX678 sensor captures detailed 4K footage with excellent dynamic range, especially at night. License plates that are unreadable on most dash cams become fully legible on the A810. The ADAS system (lane departure, forward collision warning) works well for a budget system.

JD Verified Buyer — Zhang L. ★★★★★ “Upgraded from a ¥199 dash cam and the night quality difference is night and day. License plates are readable even in dark parking lots. The parking monitoring caught a hit-and-run on my car—police read the plate clearly. Worth every yuan.”

Tmall User — Liu X. ★★★★☆ “Video quality is outstanding. Only downside is the adhesive mount can loosen in hot summer sun above 40°C. Recommend the separate suction cup mount. App connection via WiFi can be slow for video downloads.”

Best Budget: 70mai M300 (¥149)

For less than the price of a tank of gas, the M300 provides reliable 1080P recording with a wide 130° FOV. The Sony sensor ensures decent low-light performance for its class. It lacks GPS and parking mode, but for basic driving recording, it gets the job done.

JD Verified Buyer — Wang F. ★★★★★ “For ¥149, this is unbeatable. Records 1080P clearly in daylight, handles night driving acceptably. The loop recording works perfectly. I bought one for each family member’s car. At this price, no excuses for not having a dash cam.”

Verdict

Dash cams are essential safety equipment in China’s complex traffic environment. The 70mai A810 at ¥399 is the gold standard for budget-conscious buyers who want evidence-quality footage. For absolute basics, the 70mai M300 at ¥149 is better than nothing—and at that price, every car should have one.

Overall Score: 8.6/10
