True 4K. As It Should Be.

Your go-to true 4K dash cam — built for drivers who want crystal-clear footage, essential smart features, and everyday dependability.

With true 4K front and 1080P rear recording at 30FPS, the 4K A800SE captures great details on the road — from license plates to road signs — with exceptional clarity.

Its hardware-level HDR, large F1.55 aperture, and Super Night Vision algorithm work together to deliver sharp, well-balanced images in any lighting condition, whether you're driving under bright sunlight, through tunnels, or at night.

Dual-Channel Clarity in 4K 30FPS + 1080P 30FPS

Compatible with the RC22 rear camera*, the 4K A800SE supports dual-channel recording at 30FPS. Accidents and incidents don't always happen in front of your vehicle. The 4K A800SE allows you to connect a 1080P rear camera to monitor what's happening behind in real-time.

*The RC22 rear camera is an optional add-on for the 4K A800SE Set and sold separately.

Super Night Vision

The 4K A800SE combines advanced optics and a proprietary image algorithm to deliver excep-tional night vision performance — giving you clear, detailed recordings even on the dark roads.

Super Night Vision

Self-Developed Algorithm – Engineered for the Night

It features a proprietary image tuning algorithm 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 accurac consistently.

F1.55 Large Aperture – Brighter Night Footage

Compared to standard F2.0 lenses, the ultra-wide F1.55 aperture captures up to 78% more light for brighter, sharper night footage.

2G4P + IR Optical Lens – Sharper, Cleaner Imaging

The 6-layer lens structure reduces image distortion and improves contrast.

Buffered Emergency Recording

The 4K A800SE features a Buffered Emergency Recording system that 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.

*The buffer length depends on the collision's timing within the loop recording and the selected loop duration. The default loop duration is set to 1 minute, but you can adjust it to 2 or 3 minutes if needed

Loop Recording

The 4K A800SE records in a loop, automatically overwriting older files with the latest recordings, ensuring uninterrupted footage without storage concerns.

Built-in GPS

Equipped with built-in GPS supporting four satellite systems — GPS, Galileo, GLONASS, and QZSS — for enhanced positioning accuracy and coverage.

It logs your driving routes, speed, and location, ideal for travel logging, business mileage tracking, and accident verification.

Super-Sensing ADAS

The 4K A800SE is equipped with a 5-mode ADAS system that warns you in advance to minimize driving hazards: lane departure, forward vehicle start, forward collision, and adding identifications on pedestrians and cyclists to provide an extra layer of safety for your journey.

24/7 Around-the-Clock Parking Protection

G-Sensor Collision Detection

While your car is parked, if the G-Sensor detects a collision, the dash cam will automatically trigger a 30-second recording to capture the potential incident from both front and rear cameras.

*The 70mai Hardwire Kit UP03 is required and is sold separately.

Time-Lapse Recording*

When paired with the rear camera, dual-channel time-lapse recording at 1FPS during parking is supported , compressing footage for efficient storage and faster incident review.

Additionally, in this mode*, the 4K A800SE automatically adjusts exposure, gain, and noise to ensure visibility around the vehicle even in near-total darkness.

*The 70mai Hardwire Kit UP03 is required and is sold separately.

*Rear Cam RC22 is sold separately.

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.

*Please use a U3 memory card, 32GB~512GB for A800SE (there are more inferior products for this class of card on the market, with poorer durability and performance. It is recommended to use TF cards from our store which have been tested or brand cards).

Supercapacitor

Stay protected in extreme climates with a supercapacitor-powered design — from freezing -40°C to scorching 85°C (-40°F to 185°F)*.

Unlike traditional batteries, it offers a longer lifespan with up to 500,000 charge cycles, ensuring lasting reliability over time.

The large-capacity supercapacitor ensures your videos are automatically saved even during power loss, providing continuous protection and peace of mind.

*This is the working temperature of the supercapacitor component, not the overall working temperature of the A800SE.

Wi-Fi App Control & USB Data Transfer

Access and control your dash cam however you like — use Wi-Fi and the 70mai App to preview, download, and manage settings on the fly, or plug into your PC via USB for fast backups without taking out the SD card.
