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
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
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.

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:
- Watermarking information such as speed, latitude, and longitude on the video screen provides evidence records with a reference.
- 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.
