70mai 4K Dash Cam Front and Rear A810S, 4K+1080P Dual STARVIS 2, HDR Car Dash Cam with Night Vision, WiFi APP Control, 146°Wide Angle, 4G LTE, ADAS, Parking Mode with Voice Control and 128GB SD Card

Overall I am really pleased with this dash cam, it has a nice design, a good app, and clear video quality. The video quality was probably the most important factor in my choice, and so this seemed the best option given it has the top Sony sensor but is still somewhat affordable. The rear camera quality is definitely not as good, but It serves its purpose fine and is nice and small. The installation was fairly simple, apart from running the cable for the rear camera, but that's unavoidable no matter the design. I like that it comes with a 128gb micro Sd card in the box, but it could do with the CPL filter as the reflections from the windscreen do somewhat obscure the edges of the video. My only gripe would be that the footage transfer from the dash cam to the app is very slow, and so I have a micro sd card adapter in my glovebox that connects directly to my phone. Ultimately, it's a good dash cam at a reasonable price.

Best dashcam for the price , easy to install and has all the required features that’s necessary in the UK. The acceleration sensor has improved from being sensitive in older models to this one. The adas feature is a bit wavered but that’s what a camera can do. Overall a good product

Decided to upgrade from budget dash cam to something with 4k, rear camera and parking/collision detection. After watching hours of YouTube review the 70mai was chosen. To be clear if you need it want parking monitoring it requires the separate installation kit for around £20. PROS... Included 128gb micro SD. Camera is very compact and modern. Interface is easy to use Lots of settings to tweak based on personal taste, like screen on duration or audible chimes during start up ect... Comes with sticker so that dash cam isnt fixed direct to the glass if you wanted to change it in the future. Camera slides easily off it's mount so you can clean it. Cables supplied seem to be well made and long enough for the vast majority of vehicles. CONS To interact with the camera and alter advanced settings you need to activate the device hotspot within the camera and connect your phone as if it were a WiFi network. (Although the interface is pretty good once connected). The required hardwire kit really should be supplied with piggyback fuse spurs. I have to buy these separately (trust me for a constantly working connection you need these in your life!) SUMMARY This camera is in competition with other flagship models from VIOFO,VANTRUE and nextbase. For less the £200 including the hardwire kit Seems like a very fair price for piece of mind and top end dash cam functions.

I've been using the 70mai 4K Dash Cam A810 for a while now, and its video quality is simply superb. The footage comes in crisp and clear, making it reliable for recording everything from everyday drives to unforeseen incidents. The kit is impressively complete and ready to install right out of the box, and the inclusion of a memory card adds extra convenience, eliminating the need to purchase additional accessories. In terms of value, the A810 is a strong contender in the affordable dash cam category. It manages to pack in premium features without a steep price tag, making it an attractive choice for those seeking high-quality performance on a budget. However, one notable drawback is the calibration of the ADAS feature; it proved extremely challenging to set up, and for that reason, I ultimately disabled it. Another important point to highlight is the battery life. The device's internal battery life is very short, so it's crucial to have it continuously tapped into your car's power supply to ensure uninterrupted operation—relying solely on its battery is not an option. On the bright side, the night mode performs adequately, ensuring decent recording quality even in low-light conditions. Overall, the 70mai 4K Dash Cam A810 offers excellent value through its stellar video quality, comprehensive kit setup, and a range of premium features, even though its ADAS calibration and short battery life may require some workarounds.

Excellent quality day and night

Had this for a while now. Great front and rear dashcam that was easy to fit and records good quality images. Cables are all long enough to reach the rear camera threaded along the trim, plus the cigarette lighter as a temporary power point. Will add a permanent connection to the fuse board later. Link to your phone and the recordings are viewable. Very happy to recommend to others.

Great dashcam. Took a little work to fit, mainly because I wanted to hide all the wires as much as possible. But was worth the effort. Once fitted, setting it up was simple and took seconds. Video looks clear and easy to store as well.

Superb I am amazed by the quality of the hardware and the glare free 4K image, especially for a brand that I haven’t heard of before. Installation was simple. The microSD card is even included so no worrying about buying the right one The only disappointment is that the optional 4G only works in the US
