Super High Resolution of 4K UHD

The A800 pushes the limits of image quality with the industry’s highest standard up to 4K Ultra High Definition* of 3840*2160 delivering incredibly clear frames when you are on a road trip.


Outstanding Image Quality

The A800 uses 7 pieces of high-quality glasses with an F1.8 Aperture and Sony IMX415 Sensor that process frames faster to deliver a more clear and vivid image.



Dual-Vision of Front & Rear Camera

Equipped with an RC06 rear camera, the A800 can achieve dual-vision recording which allows you to capture both the road ahead of you and behind, adding another pair of eyes on the road so you can drive without fear. Install the rear camera easily without connecting cables or plugging in ports.

*In Dual-Vision mode, front camera up to 3840*2160 (4K) and rear camera 1920*1080.

Super Night Vision

The A800 uses an F/1.8 aperture lens with 3D DNR (Dynamic Noise Reduction) technology and a smart AI algorithm to reduce image noise. This allows the A800 to have outstanding low-light performance, delivering you the clearest image during any time of day or certain weather conditions.



The Advanced Driving-Assistance System (ADAS)

The Advanced Driving-Assistance System (ADAS) detects your surroundings and has real-time voice alerts to warn you of safety problems. The Lane-departure Warning System will alert you when the car starts drifting from your own lane by monitoring lane marks on the road. The Forward-Collision Warning system can recognize and monitor vehicles ahead of you, calculating their speed and space between your cars to prevent forward collisions during driving.


24-Hour Parking Surveillance

Keep monitoring when you are away. The built-in G-sensor can automatically detect sudden shakes or collisions and will start recording so that you can capture any incident while parked. You will get a notification to check your event recordings in the 70mai app if an incident happens.(No motion sensor)

*It is necessary to install the 70mai hardware kit start from firmware v1.0.6.


GPS Built-In

A GPS built-in dashcam processes the data more efficiently and faster. It acts as an accurate trip computer and can be viewed in the 70mai app. The data includes mileage, range, average speed, max speed, duration, etc. It’s great for long trips to track the exact location of an accident if one should occur.


In-app Control & Footage Sharing

Connect the 70mai APP with the dash cam’s own WiFi, you can set and control the camera within the app as well as manage, download and share your footage.

Sharing is not a problem anymore with 70mai A800. Share the footage to your insurance provider right after having an incident. Share your photos or videos to social media platforms including Youtube, Facebook, Instagram, VK, etc. Save your memories of anywhere you go and anything you see in the trip.


Loop Recording

The A800 uses loop recording to continuously overwrite older footage so you don’t need a new card once the card fills to capacity. You can check and download recorded videos in the 70mai APP.







 ❕ About parking mode, special cable (70mai hardware kit)

  1. In this model, the parking mode works only from the shock sensor (it does not work from motion ) and starts recording only a couple of seconds after the impact. Writes for 1 minute and turns off.
  2. Starting with firmware 1.6.0, to activate the parking mode, you need a proprietary special cable – “70mai hardware kit”
  3. Parking mode activation (if there is a cable) is still possible only in the DVR menu or through the Chinese application 70mai 1.9.0
  4. Parking mode is still available without a cable when manually disconnected with a button on the side. You can turn it on only in the Chinese application 70mai 1.9.0 in the settings when connected:
  5. “Settings (three dots on the top right) – Monitoring a parked car – On high sensitivity”

  7. Tandy Hoyte

    Initially I wanted to buy the previous model 70 mai cam Dash Pro. The advantage of this Registrar is that two cameras! When installed, it is not noticeable and does not interfere with the review. it came literally for a week and a half.

  8. Lakisha Mullenix

    Took the replacement dash cam pro. What I have noticed: of the pluses-it is a built-in GPS, since in pro, Luft appeared for a year and began to lose a signal from the GPS module; the ability to connect the rear camera (the camera is wired, has not yet installed). On quality while on comparison. Of the minuses, it’s a park. The mode will only work with special. Cable. In general, while satisfied. The card took 128. How do I connect everything to add feedback. Thank you seller.

    Many thanks to the seller for the prompt sending of the Registrar. Delivered extremely quickly, despite the fact that at the time of the order there was no rear camera! Packed very qualitatively and accordingly the parcel came without damage. While I checked only completeness, all in stock. After installation and test, I will add a review. I highly recommend this store, thank you!!!

  13. Eleri Barnes

  14. Franchesca Schwebach

    Recorder fire!
    I took the standard, if I buy the composite ones, immediately poured the firmware with 4pda, passed without problems, although it comes with the Russian language, but the root. On the picture there are no questions, but the flash drive is necessary good.

  15. Kawano Tanyu

    Delivery took as much as 2 months (still true and not all parcels to the RB for today have arrived), of them, 3 Weeks went to belmail after passing customs. At my request, the seller pointed to the parcel low value of the registrar’s value and no questions at the Russian customs office-no duties. This has become as long as the most expensive purchase: my kit on sale 11.11 came out at $105. Packing and packaging is worthy of famous brands, to which Xiaomi with its 70mai and refers. I will not paint advantages, because. There are many reviews on this topic on the Internet. Connected, installed in the car, poyuzal application 70mai and everything works. If something is wrong, I’ll add a tip. Seller respect and respect! Recommend.
