70mai A810 — Best Single-Channel

Price: ¥599 ($82) on JD.com | Rating: 4.6/5 (50,000+ reviews)

The 70mai A810 is the best-selling premium budget dash cam on JD.com. Its 4K Sony IMX415 sensor captures exceptional detail for reading license plates, even at highway speeds. The built-in GPS logs speed and location, and the ADAS (Advanced Driver Assistance System) provides lane departure and forward collision warnings. Night vision is excellent thanks to Sony’s STARVIS technology.

“I upgraded from a 1080p dash cam and the difference is night and day. I can read license plates clearly at 60km/h. The parking monitoring has caught two minor parking lot incidents. Great value at ¥599.” — JD.com user

Best for: Drivers who want the best video quality from a single front camera, with full GPS and parking monitoring features.

Viofo A229 Plus — Best Dual-Channel

Price: ¥698 ($96) on JD.com | Rating: 4.5/5 (20,000+ reviews)

The Viofo A229 Plus offers the best dual-channel setup under ¥728. The front camera records at 2K resolution while the rear captures 1080p, both at 30fps. The Sony STARVIS sensors in both cameras provide excellent low-light performance. The capacitive touch buttons are more reliable than touch screens in hot cars, and the supercapacitor design (no battery) handles summer heat far better than lithium-ion-powered dash cams.

“I bought this specifically for dual-channel recording after a rear-end accident where the other driver lied. The rear camera footage saved my insurance claim. Video quality on both channels is excellent, even at night.” — JD.com user

Best for: Drivers who need both front and rear coverage, especially in busy traffic areas or for rideshare drivers.

Xiaomi 70mai M300 — Best Budget

Price: ¥249 ($34) on JD.com | Rating: 4.4/5 (30,000+ reviews)

The 70mai M300 (rebranded as a Xiaomi ecosystem product) is the best ultra-budget dash cam. At just ¥249, it records 1080p with a 130° wide-angle lens and has a compact, display-free design that mounts discreetly behind the rearview mirror. Video quality is acceptable for daytime use and reasonable at night, though plate reading at speed is less reliable than higher-resolution options.

“For ¥249, I wasn’t expecting much, but the M300 delivers solid daytime footage. Night quality is acceptable for the price. It’s so small and discreet that it’s virtually invisible from outside. Perfect as a basic insurance companion.” — JD.com user

Best for: First-time dash cam buyers or budget-conscious drivers who want basic reliable recording.

Xiaomi Mijia 2S — Balanced Mid-Range

Price: ¥499 ($69) on JD.com | Rating: 4.5/5 (15,000+ reviews)

The Xiaomi Mijia 2S records at 2K resolution with a Sony IMX675 sensor and built-in GPS. It has a clean, minimalist design that matches Xiaomi’s aesthetic and features a magnetic mount for quick removal. The Xiaomi Home app integration makes it easy to view, save, and share footage. Parking monitoring works via impact detection and time-lapse recording.

“The Xiaomi app integration is great — I can check footage without removing the SD card. The 2K video is sharp enough for plate reading in good light. Night quality is decent but not as good as the 70mai A810’s 4K.” — JD.com user

Best for: Xiaomi smart home users who want seamless app integration and a clean, minimalist design.

70mai A500S — Affordable with Parking Mode

Price: ¥359 ($49) on JD.com | Rating: 4.4/5 (8,000+ reviews)

The A500S offers 1080p recording at 60fps (smoother than the standard 30fps) with built-in parking monitoring via a hardwire kit (sold separately). The Sony IMX335 sensor provides decent night quality, and the 140° wide-angle lens captures a broader field than most competitors. The optional 4G module enables remote live-viewing through the 70mai app.

“I wanted parking monitoring without spending ¥600+, and the A500S delivers. The hardwire kit installation was straightforward, and the parking mode caught a hit-and-run in my apartment lot. The 60fps recording is noticeably smoother than my old 30fps cam.” — JD.com user

Best for: Drivers who want parking monitoring features at the lowest entry price point.

Installation and Power Options

Cigarette Lighter Power: Simplest option — plug and go. Most dash cams include a long USB cable and charger adapter.

Hardwire Kit (¥30-50): Powers the dash cam from your car’s fuse box, enabling parking monitoring 24/7. Recommended for the A810, A229 Plus, and A500S.

OBD Port Adapter: Alternative to hardwiring for parking mode — draws power from the OBD-II diagnostic port. Less installation work than hardwiring.

Battery Packs: External dash cam battery packs provide parking monitoring without draining the car battery. More expensive but safer for the car’s electrical system.
