Dash cams are increasingly popular today, partly because prices have dropped significantly while the technology has improved. Among the most interesting models on the market is the 70mai A810 4K HDR, which promises high-definition video, remote control, AI features, and surveillance capabilities—all for under €200 (1400 DKK).
Here’s how my one-month trial went.
70mai A810 4K HDR: Our Pros & Cons
The 70mai A810 is an impressive Dash Cam, an all-rounder positioned as “accessible premium.” This is evident in both its sleek packaging and its extensive features. Its main strength lies in its front camera, capable of recording 4K UHD videos with outstanding visibility, even at night, thanks to HDR technology. This feature is rare in its price range and ensures clarity even in challenging conditions, like rainy days with high contrast.
While the secondary camera doesn’t match the same quality, the A810 compensates with a comprehensive hardware setup that, depending on the configuration, supports parking surveillance features. The main drawbacks are the lack of a touchscreen, which impacts ease of use, and the absence of an integrated battery, making the Dash Cam reliant on the car’s power.
What we like:
- The 4K resolution is a real plus.
- Easy to install.
- Includes everything you need.
What we don’t like:
- The secondary camera falls short.
- Connecting to the app disables screen controls.
- The materials are not of the best quality.
Prices in Scandinavia
The 70mai A810 4K HDR is available online only with Euros prices. It starts at €193.99 (1446,79 DKK) for the front camera with its display. Adding a secondary camera for rear or interior recording raises the price to €228 (1700,44 DKK).
We tested the full set, including two Dash Cams, the hardwiring kit with an OBD2 cable (for continuous operation), and an SD card, priced at €246.47 (1838,19 DKK).
A complete kit
The Dash Cam arrived with a premium aesthetic: black packaging with gold-champagne accents.
Inside, the kit includes:
- Dash Cam
- Windshield mount
- Electrostatic adhesive
- Power cable
- 12V adapter
- Tool for concealing cables
- Power cable with USB-C (for the Dash Cam) and USB-A (for the car)
If your vehicle only has USB-C ports, you’ll need an adapter.
Another box contained the 70mai UP03 Hardwiring Kit, useful for parking surveillance and connecting to the app. Speaking of the app, it’s user-friendly but has a drawback: once connected, you lose control of the Dash Cam via its integrated display, which led me to disable the app eventually.
The “premium” feel is mostly aesthetic. While well-built, the device is entirely plastic, making it lightweight but seemingly fragile. Its pyramid-like design allows easy windshield positioning, with the camera adjustable up to 90 degrees. Ports for USB and the SD card are on the right, and navigation buttons are below the screen.
The 3-inch screen has a resolution of 640×360—lower than the device’s video output but generally clear in most conditions. Installation is straightforward, and the power cable can be easily concealed under the car’s trim.
Approved video quality
The 70mai A810’s standout feature is its video quality. The front camera supports two resolutions:
- 3840×2160 (4K UHD), highly recommended
- 1920×1080 (HD) at 60 fps
The 4K resolution delivers sharp, vibrant images, allowing users to zoom in on footage—essential for identifying license plates. HDR ensures clarity in low-light and high-contrast scenarios, making plates readable even in challenging conditions.
The impressive video quality is thanks to the integrated Sony Starvis 2 IMX678 Core chip. Its wide-angle lens (150°) captures a broad field of view, with seven layers for ultra-high-definition light transmission. Combined with IR functionality and an f/1.8 aperture, the Dash Cam performs exceptionally well at night.
The secondary camera, however, is limited to 1080p and struggles with color reproduction, though it retains HDR, which helps in low-light conditions.
AI Features
Beyond video resolution, the 70mai A810 includes several smart features. The integrated GPS logs routes, which is helpful for legal or insurance purposes. However, the sensitivity settings require calibration, as even minor bumps can trigger emergency recordings.
The additional hardware kit unlocks features like:
- Time-lapse recording: Captures long periods in smaller files, though it risks missing key moments between recordings.
- Guardian mode: Monitors impacts and movement around the car, requiring continuous power via the hardwiring kit.
Snapshot functionality allows capturing incidents when away from the vehicle.
