Skip it if
Anyone unwilling to hardwire the camera, since parking mode depends on it; drivers who only need a basic front camera.
Our take
On this page
Our verdict
The A810S set is a good fit for street parkers who want both ends of the car covered and more detail than 1080p. 70mai pairs a 4K front camera on a Sony STARVIS 2 sensor with a 1080p rear camera, built-in GPS and a buffered emergency mode that keeps footage from before a collision, not just after it. A supercapacitor rather than a lithium battery is a sensible design for a car parked in summer sun.
The catch is power: 70mai says all parking features require its hardwire kit, sold separately, and the 4G remote features need yet another kit. The variant trap is the name: 70mai sells the A810, A810S and A810 Lite, and the A810S comes in front-only and front-and-rear versions. This link is the A810S front-and-rear set with a 128GB card.
Installation
The rear camera needs a cable run to the back of the car. Plan the hardwire kit and fitting together, so the cables only go in once.
FAQ
Will parking mode work from the cigarette lighter socket?
70mai says all parking features require its hardwire kit, so plan to hardwire it.
Does it include a memory card?
This listing says a 128GB high-endurance microSD card is included.
