The A800 is more than just a reliable dash cam. The Loop Recording & Evidence Protection function could ensure that in the event of an accident, the video evidence will be captured and then safely secured from overwriting. And after parking, the Parking Mode is automatically activated. Using a 3-axis gravity sensor, A800 can detect any hit-and-run collision and immediately begin recording to capture valuable video evidence.(70mai hardware kit needed to achieve the function)

Dual-vision with the Cinema-quality Video: Built around a powerful Sony IMX 415 CMOS image sensor, the A800 dash cam records 4K UHD videos with a wide-angle 140° FOV.
Super Night Vision with 3D DNR: Comes with 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.
Boosted Driving Safety with ADAS: When you start the car, A800 automatically begins recording and enables the ADAS (Advanced Driver-Assistance System) that will assist you while driving with lane-departure and forward collision warnings that help you avoid accidents.(Only Chinese)
Loop Recording & Evidence Protection: The A800 records video on a loop and stores it locally on a Micro TF memory card (up to 128GB supported) while driving.
In-app Access & Instant Share: It seamlessly connects using its own Wi-Fi for full instant access to stored videos. The dash cam also acts as a digital camera, controlled with your phone to capture any picture or view along your route.​
