The build quality is middle of the road and most of the gear is of plastic construction.
The secondary camera is only 1080p resolution and comes as a separate piece of hardware in the set.
Colors aren’t as vibrant and it struggles in tricky lighting conditions.

The A810 contains a range of extra surveillance features including night vision, parking mode, and GPS tracking.
All of these make it a great option for security-minded drivers.

The USB-C-to-USB-A and car-charger adapter will keep the dash cam powered when driving.
This is essential for making use of the parking surveillance feature.
This smaller gadget has all the features of the A810, minus 4K resolution and dual video recording.
The A810 build quality is pretty modest, with all the body parts being plastic.
This results in a noticeably lightweight unit but, at the same time, doesnt feel particularly robust.
The gear is also not particularly attractive or modern in terms of design.

The 3-inch screen has a resolution of 640 x 360.
A small lip around the screen would more adequately protect the screen from an unexpected drop or impact.
The camera can be rotated 90 degrees around the vertical orientation but this is manually operated.

Rotating it felt a little like forcing the camera in ways that it didnt feel natural to be moved.
One of the most important features of any dash cam is video quality.
The picture is crisp, with bold and vibrant colors throughout.

The backup camera doesnt, in any way, match the quality of the primary camera.
The standout feature of the A810 is its 4K video resolution at 30fps.
This video quality is down to the built-inSonyStarvis 2 IMX678 Core Chip.

The Sony chip benefits from the technology around it that captures the light.
Alongside IR functionality and a large f1.8 aperture, it can deliver great results even at night.
This is made possible by the highly sensitive image sensor and wide dynamic range.
The built-in GPS means that every route can be logged and tracked.
This is ideal for providing evidence of your vehicles location for legal or insurance purposes.
The additional hardware kit opens up a couple more features, including time-lapse recording and smart parking guardian mode.
The smart parking guardian mode tracks impact and motion around your vehicle.
This requires the hardware kit because it needs a constant power supply to function.
The additional snapshot functionality helps to capture specific incidents when youre not with your car.
The gadget is easy to set up right out of the box.
The box includes the windscreen mount, as well as the cables required for power and the secondary camera.
The mount has a well-engineered, sticky backing strip that’s easily removed and placed on the windscreen.
This mount locks securely into the dash cam and provides a very satisfying click when its in place.
All of 70mais previous dash cams had app functionality, and the A810 is no different.
The 70mai app is available on both theAppleApp Store andGoogle Play Storefor wide-ranging accessibility.
The app was straightforward to download, and connecting it to the dash cam was no trouble at all.
The app lets you control the dash cam, as well as view and download recordings.
A two-way setup would make for a far superior experience.
I see no need to limit user interaction to either the app or the gear.
Should you buy the 70mai A810?
You want a built-in batteryThe A810 needs to be plugged in to power up.
Battery-powered dash cams are available if you want to avoid the trailing cables.
I made good use of both the unit and the associated app, controlling its features through both avenues.
