70mai 4K Dash Cam Front and Rear A810S (4K+1080P) with STARVIS 2, HDR, WiFi App Control, ADAS & Parking Mode
Product description
Key takeaways
The 70mai A810S is a dual-channel dash cam built around a “good evidence in the real world” idea: it pairs a 4K front camera with a 1080P rear camera and leans on STARVIS 2 sensors, wide-angle lenses and HDR for clarity in both daylight and harder lighting. It also brings features beyond simple recording—GPS trip data with ADAS voice alerts, plus parking monitoring that’s positioned as more than a basic timer.
That said, it’s not perfect for everyone. The parking recording capability depends on a separate hardwire kit, so if you’re hoping for full functionality straight out of the box, you’ll want to double-check what you actually need before committing.
The essentials
This is a front-and-rear dash cam package designed to cover what’s happening both in front of you and behind you. The front camera uses a Sony STARVIS 2 sensor (IMX678) at 4K Ultra HD, while the rear uses a Sony STARVIS 2 sensor (IMX662) at 1080P. On paper, this combination is meant to keep fronts sharp while still giving you usable context on the rear channel.
For people who drive in mixed conditions—city stops, night commuting, and the occasional dark stretch—it’s the low-light approach that stands out. The listing highlights an F1.7 aperture (front) and a “Night Owl Vision” approach with dual HDR that aims to balance bright highlights and darker areas. In practice, this tends to be the difference between footage that’s merely recorded and footage you can actually make sense of when there’s a dispute.
There’s also WiFi app control, which makes it easier to view or manage footage from your phone without having to rely entirely on removing the card.
What you’ll notice day to day
The A810S is aimed at drivers who want safety prompts and event protection rather than only passive recording.
ADAS safety alerts are included, with voice alerts for collision risks and lane departures. This isn’t the same as having a full driver-assist system, but it can help you stay aware of specific hazards while you’re on the move.
Emergency video pre-recording is another practical inclusion. The system is described as stitching footage before and after an event, with the ability to capture a window from 10 seconds to 3 minutes before the trigger and create an emergency video file up to 210 seconds before the accident occurs. That “before” context is where many basic dash cams feel a bit too late.
A small, realistic caveat: features that sound impressive on paper only help if they’re enabled, triggered correctly, and set up cleanly in your vehicle.
Key features for clarity, evidence and control
The camera setup is built around broad coverage and visibility.
- Wide-angle lenses: the front lens is listed as 146° and the rear as 130°, which should help reduce blind spots compared with narrower setups.
- HDR handling: dual HDR is positioned to cope with contrast extremes—night roads, tunnel exits and glare from headlights.
- Loop recording: it supports seamless loop recording so newer footage can overwrite older footage when the storage is full.
- Built-in GPS support for trip reports: quad-mode GPS supports GPS, GLONASS, Galileo and BeiDou and records speed, location and time, syncing to the 70mai App.
If you care about having time/location context alongside the video—useful for personal records and potentially helpful in claims—this is one of the more meaningful additions.
Parking mode: where it gets interesting (and where buyers should be careful)
The A810S includes 24H AI parking surveillance with time-lapse recording. The AI motion detection can identify suspicious activities and automatically start recording. Time-lapse is described as compressing longer parking hours into viewable clips (for example, 1 minute from 15 minutes), using low power consumption.
However, the listing is clear that parking monitoring mode requires a 70mai hardwire kit (sold separately)—it names UP04, UP03 and UP06 options. So, if your plan is “fit it like a standard dash cam and forget it”, you may find the parking features don’t fully unlock without extra parts and installation.

Should you buy it?
A solid pick if you want a dual-channel dash cam that prioritises low-light clarity, includes HDR/night-focused tech, and gives you more than just “record after the fact” thanks to emergency pre-recording. It also makes sense if you’re likely to use the companion app for viewing/control and you value GPS trip context plus ADAS voice alerts.
It might not be a great match if you only want basic recording without any extras, because the parking monitoring mode depends on buying a compatible 70mai hardwire kit separately. Also, if you’re sensitive to the idea of setup and enabling features, you’ll want to be deliberate with installation and configuration.
