The catch
70mai A810 Lite
Parking recording only works with the separately powered hardwire setup.
Side by side
70mai A810 Lite vs ROVE R2-4K Dual Pro: A 2K rear view and an included card are what ROVE adds to the front-camera decision
Quick verdict
Go for the A810 Lite if your main needs are native 4K front video, a clear screen and quick phone transfers. Go for the ROVE if you want a 2K rear view and care about the 128GB card, the polarizer and the 1TB storage path.
Before you buy
Why, and what it costs you
Where these two really part ways
70mai A810 Lite is the better match for “I want the camera to sit tucked in behind the mirror” and “I want footage that starts before a parked impact”. ROVE R2-4K Dual Pro is the better match for “Long driving shifts come before I can save footage” and “The windshield shows reflections of my dashboard”.
Where this comes from
This lines up the current strong and useful fit ratings for the exact products. It does not roll them into one overall score.
The catch
ROVE R2-4K Dual Pro
Routing the rear cable through a hatch or headliner still takes care.
