Built around a powerful Sony IMX 415 CMOS image sensor, the A800S dash cam records 4K UHD videos with a wide-angle 140° FOV. Combined the optional rear cam*, every important detail in the front or rear of the vehicle can be recorded clearly to provide irrefutable video evidence or capture the landscape along your journey with cinema-quality video.

Outstanding Image Quality

The A800S uses 7 pieces of high quality glasses with F1.8 Aperture and Sony IMX415 Sensor that process frames faster to deliver a more clear and vivid image.

Super Night Vision with 3D DNR

The A800S achieves stunning video and vivid, clear images even in low-light conditions using a 3D DNR (Dynamic Noise Reduction) tech, F/1.8 aperture lens and a smart algorithm that significantly reduces image noise and automatically adjusts the exposure balance. The result is enhanced night vision with greater details.

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 the space between your cars to prevent forward collisions during driving.

GPS Built-In

A GPS built-in dash cam processes the data more efficient and faster. It acts as an accurate trip computer and can be viewed in 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.

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 70mai app if an incident happens.(No motion sensor)

*Since firmware v1.0.6 you need to install 70mai hardware kit.

In-app Control & Footage Sharing

Sharing is not a problem anymore with 70mai A800S. 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 A800S 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, 70mai hardware kit

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

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.

Starting with firmware 1.6.0, to activate the parking mode, you need a proprietary special cable – “70mai hardware kit”

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

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:
“Settings (three dots on the top right) – Monitoring a parked car – On high sensitivity”

    Посылка приехала за 5 дней, лично в руки. 15го декабря заказал, 20го курьер привез. Упаковано было отлично, ничего не помялось, коробка целая. Всё проверил, работает отлично. С телефоном связывается без проблем: обновил с прошивки 1.0.3 до 1.0.10, никаких танцев с бубном, всё с телефона. Боялся лотереи, в форумах пишут, что многие образцы “мылят”. Мой образец снимает чётко. Чуть расстроился, когда почитал 4pda уже после покупки – оказывается к этому регистратору всё таки подходят другие камеры заднего вида 70mai, которые имеют внешнее исполнение. Можно было купить без этой камеры заднего вида и докупить другую. Ну уж что купил, то и буду использовать. Регистратор отличный, продавца рекомендую!

    Month to Ukraine. Quality at altitude, best offer. I installed both cameras myself for about an hour. All the cables are hidden. Very satisfied, the quality of the video from both cameras is very cool. Advice, if you need monitoring in the parking lot, then take a complete set with the “Park kit”. I recommend it.

  22. K***n

    Регистратор очень хорошего качества. Запись видео как с хорошей камеры

  23. X***n

    Finally I have hardwired the A800S with the hardwire kit into my Honda Pilot. To my surprised, the Parking Surveillance function not works. It just said no surveillance cable connected and refused to turn the option on. You should stop put the false information in your ads. Also, the sensor is too sensitive and keep fire false alarm and start emergency recording while I driving normally.
