VAT included.
In stock
The 70mai Dash Cam 4K A800SE is a 4K dashcam with great value for money. It films in true 4K with HDR and offers a wide 140° view. The bright F1.55 aperture keeps license plates readable even in the evening. The built-in GPS records your route and speed, and on the 3-inch screen you can instantly replay a recording. With the RC22 rear camera, it also films what's behind you.
The ANWB noticed this too. In the 2025 Dashcam Test, ten 4K dashcams were tested, and the A800SE finished third with a 7.7. That earned it the "Best Value" rating. The two models ranking above it cost one and a half to three times as much.

ANWB Dashcam Test 2025 Award Winner
In 2025, the ANWB tested ten dashcams that record in 4K or higher. The test team evaluated the footage in bright daylight and in the dark, and also looked at ease of use and the parking mode. The A800SE earned the title Best Value, with a final score of 7.7 and four stars.
During the day, according to the ANWB, the A800SE is among the three dashcams that clearly stand out from the rest: high contrast, sharp and with lots of detail. It also performs well in the dark. License plates often remain readable in low light.
When it comes to performance, according to the ANWB, it leaves more expensive dashcams behind. You can read the full test report on the ANWB website.
Three reasons to have a dashcam
In a collision, in the parking lot, and on the road during your holiday.
In the event of a collision
Not sure who's at fault? Let the footage do the talking. The emergency recording saves up to 3 minutes before the crash, including your route and speed.
In the parking lot
A dent and no note under the windshield wiper? The collision detection captures it, 24 hours a day. For that, you'll need the separately available 70mai Hardwire Kit UP03.
During a road trip
You want to keep that coastal road from your vacation. The camera is already recording anyway, and thanks to WiFi 6 and the 70mai app, the clip lands straight on your phone.
Real 4K with HDR and a 140° viewing angle
The A800SE films in 3840 x 2160 pixels, without upscaling. That's why license plates and traffic signs stay readable even a few car lengths away.
HDR keeps light and dark in balance. Think of exiting a tunnel, oncoming headlights or a road with harsh shadows.
The bright F1.55 aperture and Super Night Vision keep the footage usable at night. The lens has a wide 140° view, so you capture the full width of the road.
3-inch display and built-in GPS
On the 3-inch screen you line up the camera perfectly right when mounting it. After an incident, you play back the recording on the spot, without having to grab your phone first.
The built-in GPS uses four satellite systems and records your route, location and speed alongside the footage. In case of a claim, you'll have more than just a video clip.
The Super-Sensing ADAS driver assistance has five modes and warns you in advance about traffic situations. Via wifi 6 and the 70mai app, you view and download your recordings right on your phone.
Expandable with the RC22 rear camera
With the RC22 rear camera you also capture what happens behind you. It films in full HD with a viewing angle of about 130°, and HDR too.
Front and rear come together on a single microSD card. With the A800SE Front + Rear Camera version, the RC22 is already included. With the A800SE Front Camera you buy it separately later on.
With the separately available 70mai Hardwire Kit UP03, the camera also keeps an eye on your parked car. Collision detection and time-lapse then run 24 hours a day, with five sensitivity settings.
How does the Xiaomi 70mai Dash Cam 4K A800SE compare?
Three dashcams that record in 4K at the front, all with GPS and WiFi 6. The A800SE was named Best Value Pick in the ANWB Dashcam Test 2025 and can be expanded with a full-HD rear camera. The A900 and A900 Ultra also record in 4K at the rear.
