Overview
The 70mai A810 Lite is a dual channel dash cam recording 4K up front and 1080p from the rear, with a built in 4G LTE modem and 5GHz Wi-Fi 6 for remote viewing and quick clip transfers to a phone.
It runs on a supercapacitor rather than a battery, which 70mai positions as more stable in temperature extremes, and its compact body is meant to tuck behind the rearview mirror without blocking the view. Full 24 hour parking mode is supported but requires one of the UP03, UP05 or UP06 hardwire kits, sold separately, and paid installation help is only offered in New York and California.
- 4K front, 1080p rear dual recording
- 5GHz Wi-Fi 6 plus 4G LTE remote access
- 3 mode GPS: GPS, GLONASS, BDS
- Supercapacitor design, 18 month warranty
Who it's for
Commuters and rideshare drivers who want sharp front footage and the option to check the car remotely over LTE. Less suited to anyone who wants full overnight parking coverage without buying a hardwire kit.
Strengths and trade-offs
Drawn from this product's published specifications.
- 4K front recording with 1080p rear for dual coverage
- Wi-Fi 6 for fast clip transfer without removing the SD card
- Built in 4G LTE for remote live view
- Supercapacitor build rated for temperature extremes
- 24 hour parking mode needs a separately sold hardwire kit
- Paid installation support is only available in New York and California
Performance notes
The F1.55 aperture and HDR processing are aimed at keeping headlight glare and dark shadow areas readable at night, while the 3 mode GPS (GPS, GLONASS and BDS) logs speed and route for playback. Parking mode combines G-sensor impact locking with time lapse recording so it can run for long stretches on low power once wired in.

Questions about the 70mai A810 Lite-RC21-64GB

Yes, but 24 hour parking mode needs the separately sold UP03, UP05 or UP06 hardwire kit.
What resolution is the rear camera?
1080p, while the front camera records at 4K (3840x2160).
Does it use a battery?
