Dual-Channel with Outstanding Image Quality

The A800S uses 7 layers of high quality glass lenses with F1.8 aperture and Sony IMX415 Sensor that process frames to deliver images with better clarity and vividness.

(Note:Front Cam cable length:3.5M, Rear Cam HDMI cable length: 5.5M)

Super High Resolution of 4K UHD

The A800S pushes the limits of image quality with industry's highest resolution standard–up to 4K Ultra High Definition of 3840*2160P–delivering incredibly clear frames when you are on a road trip.

Powerful Night Vision

The A800S uses an F1.8 aperture lens with 3D DNR (Dynamic Noise Reduction) technology and smart AI algorithm to reduce image noise. This gives the A800S outstanding low-light performance, delivering clear images during any time of day or under certain weather conditions.

Advanced Driver-Assistance Systems (ADAS)

The ADAS will detects your surroundings and uses voice alerts to warn you of safety problems.

Built-in GPS

Monitors and displays real-time trip data including time, speed(km/h,mph), and coordinates. Tracks the exact location of an accident if one should occur, crucial for roadside assistance and insurance claims.

24-Hour Parking Surveillance

Keep monitoring when you are away. The built-in G-sensor can detect sudden shakes or collisions while your car is stationary, and will automatically start recording to capture any potential incidents. If an emergency video is recorded, the dash cam will notify you through voice alert once it's turned back on.

In-app Control & Footage Sharing

The 70mai App supports both iOS & Android systems,allowing you to view and download HD videos in real time through the dash cam's Wi-Fi. It also locks emergency videos to the “Event File” to prevent an overwrite.

Loop Recording

The A800S uses loop recording to continuously overwrite loder footage so your memory card does not run out of space. You can check and download recorded videos in the 70mai App.

70mai Hardware Kit

For Parking Surveillance Mode, the 70mai Hardware Kit ensures power for the 70mai dash cam to continue operating while the car parked.

To ensure the 70mai Dash Cam A800S works well, PLEASE MAKE SURE you have purchased the compatible SD card (Lexar High-Endurance 64GB Micro SD Card).

NOTE:The memory card may become damaged or deteriorated after repeated cycles of overwriting, and this may affect its ability to save video and image files.

lf this occurs, immediately replace it with a new memory card.

  1. M***g

    Shipping was fast and so was the delivery to Italy, unfortunately the package was missing an important part. I have ordered the full set with front camera, back camera and cable for parking surveillance but the cable was missing. I have tried to solve the problem but the store kept telling me that he had shipped everything and was sending me print screens of things written in chinese. Bad experience

  2. Customer

  7. L***a

    Recebi o produto funcionando porém deixou de ligar com menos de uma semana de uso, não passa da tela inicial com os dizeres “70mai”, tive que provar por vídeo ao vendedor que o produto estava defeituoso, mas mesmo assim exigiram que eu ou devolvesse mas o custo de envio é de mais de R$300,00 sem qualquer garantia que chegaria ao destino uma vez que não tem nota pra anexar e a alfândega pode barrar. Resumindo se comprar saiba que se der defeito o prejuízo e todo seu.

    You a nice Dashcam, but that leaves bitter taste, you don’t understand because despite the say consumerebbe too but is absurd since it is standby, but though even being aware of this, I would poterla activate even without cable! In most seen that there is option I wish the assembly cable was at least provided, instead you are obliged to buy it separately. Filming face 4k are excellent, would however was preferred a 170 degree angle because 140 is somewhat limited. The rear camera Full HD I think is to limit dell’accettabile as filming and that everyway is probably more suitable for filming cabin. The Assembly if you have a little practice, is as simple as any other dashcam, otherwise please turn to a refinisher for cables. App good.

    Everything is lovely. I understand the card. Ektri. Others don’t want to work.

  14. A***z

    Fast shipping, I received in 36h since I placed the order. Commenting on parking surveillance still having set up in high sensitivity is very likely that the blow you get in your car will not be recorded, since in order for the camera to start recording on such surveillance, it must have a strong impact (another vehicle, object to your ndent, ro Your ra of crystals if it recorded) In case of scratches, normal blow, theft of pieces, I’m afraid I wouldn’t record anything. Still seems like a very useful vehicle accessory to me. The installation is simple and in about 1h would be finished. If you purchase the parking surveillance kit (continuous power cable) you must install it as follows: [Black Cable = mass]-[red Cable = 12v at all times]-[yellow Cable = 12v only when you want it to start recording, when making contact for example]

  15. P***u
