True 4K with Hardware HDR

The 4K A800SE records true 4K UHD (3840x2160) at 30FPS, delivering sharp, vivid footage of crucial details. Its hardware-level HDR ensures balanced, natural video by perfecting shadows and highlights, ideal for all lighting conditions, including challenging scenarios like tunnels or night driving. This means clear, confident, and uncompromised evidence when it matters most.

Super Night Vision

A proprietary image tuning engine designed for low-light conditions. It reduces noise, balances exposure, and controls glare, enabling the dash cam to deliver clear night footage with enhanced color accuracy consistently.
Compared to standard F2.0 lenses, the ultra-wide F1.55 aperture captures up to 78% more light for brighter, sharper night footage.
Hardware-level HDR pulls detail from both dark and bright areas,ensuring natural, balanced footage in tunnels, glare, and nighttime.

Buffered Emergency Recording

The Buffered Emergency Recording system now captures up to 3 minutes before a collision, along with 30 seconds after the impact. This ensures you don't just record the accident — you capture the full context leading up to it and what happens next.

Loop Recording

The 4K A800SE records in a loop, automatically overwriting older files with the latest recordings, ensuring uninterrupted footage without storage concerns. Crucially, all emergency and parking surveillance videos are protected in separate "Event" and "Parking" folders, preventing them from being overwritten by regular loop recordings.

24H Smart Parking Surveillance

When parked, if the G-Sensor detects a collision, the dash cam automatically records a 30-second incident video. You'll receive a voice alert about the recording upon restarting your car.
When paired with a rear camera, the 4K A800SE supports dual-channel parking time-lapse recording at 1 FPS. This compresses footage for efficient storage and quicker incident review. In this mode, the camera also automatically adjusts exposure, gain, and noise, ensuring clear visibility and usable footage even in dimly lit parking lots or shadowy streets. This means you can confidently review what happened around your parked car, even at night.

Supercapacitor

Unlike traditional batteries, the supercapacitor excels in high-temperature—supporting full operation from -10°C to 60°C and withstands up to 500,000 charge cycles. Its robust design offers
safer, greener performance and ensures nonstop protection when it matters most.

Wi-Fi App Control

Effortless control, flexible transfers. The 4K A800SE features built-in Wi-Fi 6 (2.4GHz) for faster, more stable connectivity. Simply connect your phone to the dash cam's hotspot via the 70mai App to preview, download footage, or adjust settings in real time—no cables needed.

USB Data Transfer

For PC users, the USB flash drive mode makes file transfer easy without removing the SD card. Just plug and go.

Up to 512GB Storage Support

More space for what matters. The 4K A800SE supports microSD cards up to 512GB, allowing for extended recording time and reducing the risk of overwriting important videos.

Built-in GPS

Equipped with built-in GPS supporting four satellite systems (GPS, Galileo, GLONASS, and QZSS), the 4K A800SE offers enhanced positioning accuracy and coverage. It logs your driving routes, speed, and location, perfect for travel logging, business mileage tracking, or accident verification. All data is easily accessible via the 70mai App.

Super-Sensing ADAS

Equipped with a 5-mode ADAS system, the 4K A800SE actively minimizes driving hazards. It provides advance warnings for lane departure, forward vehicle start, and forward collision, and now includes pedestrian and cyclist identification for an extra layer of safety on your journey.

Does parking surveillance function support sensitivity setting?

The difference between each level of sensitivity is in the judgment of collision recognition, the higher the sensitivity setting, the easier to trigger.

What is the purpose of GPS (global positioning system) on the dash cam?

With the dash cam's built-in satellite positioning module, the vehicle's current location information can be retrieved in real time, allowing for the following additional safety functions:

  1. Watermarking information such as speed, latitude, and longitude on the video screen provides evidence records with a reference.
  2. Dash cams record every trip your vehicle takes and summarize that information into a driving route that can be used as a reference for historical trip statistics.
Why is the video data stored in the dash cam not readable when it is directly plugged to the computer?

Please use a data cable with a data transmission function. The dash cam is equipped with a power cord without data transmission function.
