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.

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
