Something I’ve learned over the past several years is that although most dashcams look similar, every one of them is different. The specs on all of these cams sound pretty similar, but it’s not until you’ve hooked one up and used it a few times that you can really determine whether or not it’ll stay on your windshield or wind up in a junk drawer.
I’ve spent the past few weeks testing the A810 Lite dash cam, a dual-camera system from 70mai that includes two cameras: a forward facing 4k dash cam and a 1080p rear facing camera.
What’s in the box?
70mai actually sent me two separate products to test. The first was the A810 Lite 4k dash cam, which comes with everything you need. Both cameras some with mounting brackets and 3M adhesive that allows you to attach the cameras to the inside of your front and rear windshields. The main camera is powered by USB-C, and included is a 12v-to-USB adapter. Also in the box is a trim tool for tucking wires into your vehicle’s interior, and a handful of small cable routing mounts. The rear camera connects to the front camera with a generously long cable. I was able to run the cable from the windshield of my Ford E-250 van up the windshield, over to the driver’s side, all the way down the entire length of the van, and over to the rear window. Videos are recorded locally to a Micro-SD card, and a 64gb one is included.
The second product 70mai send me to test was their 4g wiring kit. Once wired directly into your vehicle’s fuse box, this device allows your cam to be accessed from anywhere at anytime. The kit is not required and you’ll need to provide your own sim card and service to use it, but if you want to turn the A810 Lite into a 24 hour security system that can be accessed from anythere, this is how you do it.
Installation and Use
Installing the A810 Lite is as simple as sticking the cameras to your front and rear windshields, hiding the cables, and connecting power to either a USB-C port or using the included 12v-to-USB adapter. Once powered up, the A810 starts recording — it’s that simple. On the bottom of the camera there are four physical buttons that can be used to navigate menus, stop and start recording, and perform other functions.

70mai also offers an app, which makes setting this camera up and accessing its functions to much more convenient. The app is available for both Apple and Android (QR links are included in the manual). The app can connect to the camera using WiFi and allows you to perform all the configuration options, view your recorded clips, and download your videos and photos directly to your phone’s camera roll.

Wiring up the optional 4g wiring kit is a little more involved, but if you’ve ever wired up a car stereo or any simple electrical kit you’ll have no problem. The device comes with pre-attached wires that need to be run to your vehicle’s fuse box so it has power even when the vehicle is turned off. This kit turns the A810 Lite into a 24-hour security system that can notify you if someone bumps your vehicle while you’re away from it and also allow you to check your footage from anywhere you have a cellular signal.
Quality and Ease of Use
To be honest, I don’t know if I have ever tried or used a simpler dash cam. While the menu and app offer tons of features with things like time-lapse recording, adding and removing watermarks, and flipping the video vertically and horizontally, once you apply power to the unit it starts recording and really that’s all you need to do.

The A180 Lite gives you true (not upscaled through software) 4k video from the front cam and HD 1080p from the rear. I found the quality of both cameras more than acceptible. Especially through the 4k camera I was able to make out license places of cars off in the distance and all kinds of detail. By design the 1080p camera is less detailed, but we’re still talking 1920×1080 resolution. Both cameras looked good to me.
At night, the cameras struggle a bit in low-light situations. For the most part I found they worked okay, especially when there were street lights or other lights nearby, but there were times when it was dark that I found the picture to be a bit washed out and/or muddy. That being said, this is a sub-$100 4k dash cam which is an incredible deal. For one with advanced low-light recording, expect to pay 2x-3x this amount.
What Could Be Better
My only real complaint with the unit was the included 64gb Micro-SD card. With both A810 Lite cameras recording in native 4k and 1080p, the SD card was able to store around 185 one-minute video clips (approximately three hours) for each camera. For in town trips this is probably fine, but if you want to retain more footage, you’ll either want to spring for a larger SD card (up to 512gb cards are supported), sign up for 70mai’s cloud storage service, or lower the resolution of the front cam from 4k to 1080p.
Overall Quality and Value
There’s no question that this dash cam is a great value. For under $100 you’re getting two cameras, one 4k and one 1080p, along with all the cables and hardware needed for installation, an SD card, and the free app that allows you to view your cameras in real time, access pre-recorded clips, configure the system, and download all your footage.
Most of the other dash cams I’ve tested always have a deal breaker. Either the software doesn’t work (or worse, requires you to circumvent security settings to install), or the 4k footage is really 1080p footage being upscaled via software, or it’s a hassle to hook up. The A810 Lite 4k dash cam from 70mai has none of those issues. It’s a solid 4k dash cam solution for less than $100. You’ll be seeing a lot more of this dash cam in future episodes of Big Rob’s Van.
