Dash cam 70mai A810S 4K Ultra HD, 3840×2160, 146° FOV, 3 inch IPS, Wi‑Fi 6, GPS, MicroSD up to 512 GB, cigar lighter power

70mai A810S is a single‑camera dash cam that records in 4K Ultra HD (3840×2160) with a 146° field of view and a 3" IPS display. Built‑in GPS logs location, speed and time while Wi‑Fi 6 and Bluetooth enable fast file transfer and remote control via the companion app. The unit accepts MicroSD cards up to 512 GB and uses the vehicle cigar lighter for power. The dash cam employs Sony STARVIS 2 sensors and 70mai image processing (MaiColor Vivid+ and Night Owl/Lumi Vision) to preserve detail in both bright and low‑light conditions, and it includes AI motion detection, buffered emergency recording and a supercapacitor for improved temperature tolerance.

Advantages

The A810S provides high‑resolution 4K footage for clearer identification of vehicles, road signs and license plates while adaptive image algorithms enhance exposure and color in backlit, tunnel or nighttime scenarios. Built‑in GPS and ADAS add context to recordings by logging precise position, speed and providing driver alerts. AI Motion Detection and parking surveillance capture suspicious movement and synchronized dual‑channel recording for fuller evidence. Wi‑Fi 6 enables quick downloads and live streaming via the app, while the supercapacitor increases reliability in extreme temperatures.

How to use

Mount the dash cam on the windshield using the supplied bracket so the lens has an unobstructed view of the road. Insert a compatible MicroSD card (up to 512 GB) and connect the power cable to the vehicle cigar lighter socket. Configure time, date and GPS in the device menu, then pair the camera with the 70mai mobile app via Wi‑Fi or Bluetooth to enable live view, remote recording and settings adjustments. Use the app to stream video, download files over Wi‑Fi 6, receive instant incident alerts and access Find My Car and live route tracking features. For parking surveillance enable AI Motion Detection and connect an optional hardwire or 4G kit if remote 24/7 monitoring is required.

Recommendations

Use high‑endurance MicroSD cards rated for continuous dash cam recording and format the card in the device before first use. Set appropriate G‑sensor sensitivity and enable buffered pre‑event recording to capture the full sequence around incidents. Keep firmware and the companion app updated, and if you require uninterrupted remote monitoring pair the camera with a suitable hardwire kit or 4G module. For optimal night results, leave automatic night modes active; position the lens to avoid reflections from the dashboard and check GPS lock after installation.
