The 70mai 4K A800SE-4G is a dash cam that records in true 4K resolution - no interpolation, no compromise. Record, monitor and protect your car from anywhere in the world, day or night, while driving or parking.

Sharp images in all lighting conditions
The front camera captures images at a native resolution of 3840×2160 at 30 frames per second - without any scaling. Every license plate and road sign is captured with photographic accuracy. Hardware HDR processes the image directly on the sensor, bringing out details in both dark tunnels and blinding backlighting.

Full protection for the front and rear of the car
Connect the RC22 rear camera for smooth 30 FPS recording - front in 4K and rear in 1080P. Aggressive rear-end collisions, parking lot collisions or fleeing the scene of an accident - the rear camera captures every situation reliably and in full quality.
The RC22 rear camera is an optional accessory for the A800SE 4K DVR and is sold separately.

See more than others after dark
A proprietary image processing algorithm reduces noise and controls glare in real time. The F1.55 aperture lets in 78% more light than standard F2.0 lenses, providing brighter, sharper nighttime images. Hardware HDR extracts detail from dark and bright areas simultaneously, maintaining a natural look in tunnels and extreme lighting conditions.

Your car is always within reach
With 4G connectivity, you can see your car live - whether it's parked or driving with another driver. Instant alerts let you know about collisions and suspicious incidents. Geo-Fence alerts you when your vehicle leaves a designated area. Live GPS Tracking tracks your route in real time, Find My Car guides you to your car in crowded areas, and important alerts are automatically uploaded to the cloud.
Requires 4G hardware kit, sold separately.

Records the entire event, not just the moment
Emergency buffered recording system records up to 3 minutes before a collision and 30 seconds after the event. Clips are automatically saved in a dedicated "Emergency Video" folder where they cannot be overwritten by standard looping recordings. This provides full context of the event - indispensable for insurance disputes and post-accident investigations.

Record continuously, without worrying about location
The recorder automatically overwrites older files with the latest recordings, ensuring there is always plenty of space on the card. Emergency and parking recordings are stored in separate "Event" and "Parking" folders and are permanently protected from deletion by standard looping recordings.

Four satellite systems in one
The built-in GPS simultaneously supports four systems: GPS, Galileo, GLONASS and QZSS, ensuring high positioning accuracy in any terrain. Routes, speed and position are automatically recorded and accessible via the 70mai app.

Five alerts that could save your life
ADAS is an advanced five-alert system that works for you 24/7 to keep you informed:
Lane departure
Vehicles in front of you
Distance between vehicles
Pedestrians on the road
Cyclists in a blind spot
It's like having an experienced instructor who never sleeps and is constantly watching the road. They won't replace your attention, but they will be your extra eye that can prevent an accident before it happens. Safety is not just about recording - it's about anticipating danger.

A collision in a parking lot? The camera will record it
When a collision occurs with a parked car, the G-sensor instantly triggers a 30-second recording from both cameras. After restarting, the dash cam alerts you with a voice message that the event has been recorded and secured.
Parking mode requires the 70mAi Hardwire Kit UP03, which is sold separately.

Day and night parking monitoring
Time-lapse recording at 1 FPS (frames per second) records both channels even when the dashcam is at rest, compressing the footage to a manageable size. In parking mode, the camcorder automatically adjusts exposure, gain and noise reduction to capture clear images even in near total darkness in a parking lot or on darkened streets.
Parking mode requires the 70mai Hardwire Kit UP03, sold separately.

More space for important recordings
The dashcam supports microSD cards from 32GB to 512GB, greatly extending continuous recording time and reducing the risk of accidentally overwriting important footage before you can review and secure it.

Works in extreme temperatures
Instead of a traditional battery, a supercapacitor is used that operates in a temperature range of -10°C to 60°C and lasts up to 500,000 charge cycles. This ensures reliable and continuous operation.
