I've been using dash cameras in 4 different cars over the last 10 years. When picking out cameras in the past, I would read the reviews and would pick them out not only based on good reviews, but affordability as well. It wasn't until recently when I went to pull the footage off of one of my cameras, that I found it hadn't been recording even though it said it was! I decided to check my other vehicles and found that another camera, different brand and design, had been doing the same thing! In the past, I had considered camera features when choosing cameras, but had really only considered things like that it was recording in 4k, but most cameras with the fancier features seemed to be out of my price range. After having had these 2 cameras fail me in what mattered most, I decided that I was no longer going to leave something so important up to cheap cameras. I looked into more features and decided to raise my price limit, knowing that it would be worth it to pay more for a camera knowing that in doing so, it could save me thousands of dollars some day. About this camera: Materials - The camera itself is a solid unit. It doesn't feel cheaply made. It is a smaller unit so it doesn't take up a ton of space on the windshield, but it isn't so small that you can't see or read what is on the screen. Mounting - Mounting it to the window was a bit more complicated than the cheap cameras with rubber suction cups, but if you follow the directions and watch the videos, it isn't bad at all. Once it is installed, it doesn't move or vibrate, so it gives a much better quality picture. Picture - The picture is excellent! The wider angle is great to make sure you don't miss anything, and the picture is crisp and smooth. No choppy video and nothing blurry at all! Night Time - The night recording is also decent, picking up lots of detail my other cameras did not. Rear Camera - Having the rear view camera is an added level of protection that I only had on 1 of my previous dash cameras, and on my old camera it only worked for a couple of weeks before breaking. The rear view camera on this one records better than the forward facing cameras on all of my previous cameras. Connectivity - Once you set up an account, it makes it easy to manage multiple cameras between different vehicles, and it is then super easy to pull footage from the camera when you need it. No need to remove the SD card or plug in a cable; it's all wireless! Memory - This thing supports a huge memory card. My previous cameras were limited to mostly 32gb, one allowed up to 64gb, but this one will handle up to 256gb! Features - The GPS capability is cool, but honestly I don't know a lot about it. I do know that it has a strong connection in my area. Also, the G sensor definitely works to lock footage when it detects an abnormal event. I may have it too sensitive even as it sometimes locks footage when I hit a big bump in the road, but that can easily be adjusted. Overall, the only thing I could mark this down for is the price as it is over $100, but honestly that is a small expense if it gives you quality footage of an event that saves you tens of thousands of dollars where a cheap camera would have failed you. Even being as "expensive" as it is, for the features it has it is actually pretty affordable compared to similar cameras. It's worth it, you don't want the regret of going with a lesser camera.

I have tested a few dash-cams before settling with the 70mai 810 4K. This is a well built camera all around. It gets mounted very easily if you choose to use the cigarette lighter adapter and only use the front camera. If you choose to hardwire and add the rear camera it takes a little more effort but not very difficult to get it done by yourself. It took me less than hour running cables trough headliners and under the panels. the quality of the front camera is very good both day time and night time. The 4K resolution gets the frame rate reduced to the 25 fps but it does not make any significant impact. The rear camera though is not as good as you would expect since it supports HD resolution only. I wish it was supporting 1440p resolution on the rear camera. This camera has a nice ADAS features which probably taxing the processing power hence the reduced frame rate in 4K and low resolution in the rear cam. If your car does not have a ADAS features, it is nice to have such a feature but it may get annoying since the lack of native integration to your vehicle. for example, it will keep throwing lane departure warning even when you change lance intentionally because the camera does not know your blinker is on. the other weird thing with the ADAS is the warning messages does not make sense. only lane departure warning make sense. when the forward collision detection kicks in the voice warning announce it like "front threat car" which does not make any sense. It seems to poor translation from Chinese to English. I turned it off since my car has quite well ADAS system but for an older vehicle it may be useful to use. the app is very nice and unlike the other cameras the app is capable of doing firmware upgrades over wifi without any manual steps with an SD card which is a great convenience. other unique feature of the App is providing recorded videos in a timeline and marks the events with color codes. If you have a ring doorbell or camera you would know what I mean. This is the hands down best app to find and see recorded events, very intuitive. over all I really like the camera and how it performs so far. But there are a few things that needs improvement to my openion. - allow 30fps recording when the ADAS is turned off - improve the rear camera to support 1440p (quad HD) resolution - use standard interfaces all around. the rear camera connector is proprietary instead of usb-c as most of the vendor chose to use. - use standard signaling for the parking mode. the parking mode should be operating when it is used with a 3rd party or an existing hardwiring kit. just an important heads up if you are planning to hardwire or contemplating to keep using an existing hardwire kit with any 70mai cameras. the parking mode will not if it is not a 70mai hardwire kit which makes it difficult for many users. either you have to rerun a new hardwire kit for the parking mode and you need to fine without parking mode. in my case, I chose not to use the parking mode to be able to keep using the existing hardwire kit on my car. simply I didn't want to waste another hour to replace perfectly working kit with an exact same one just because 70mai chose signaling parking mode differently on their cameras. This is something you need to keep in mind

Seems like a great little dashcam. I bought it two months ago but only got around to installing recently since I wanted to do the hardware install and wasn't immediately up for pulling apart the car's interior. I've only installed the front camera so far, because similarly routing the cable for the rear camera to the window on my car's rear hatch will involve more contortions, and it's too hot here in central CA for that right now. Pros: 1) The image quality is great. Daylight is fine; haven't tried at night. 2) It's very simple to operate. The menus are intuitive. 3) The LCD screen is easy to see, even in bright sunlight. 4) Power consumption is nominal. When both camera are on they appear to draw about 600mA max. 5) I really like the Android app. Cons: 1) The electrostatic mount didn't work. After the camera fell off for the third time, I just stuck it to the windshield. 2) This is more for the UP03 hardwire kit, but instead would be a great option to incorporate into future cameras. The hardwire kit has a 11.8V cut-off to avoid draining the 12V battery. We have a Ford Mustang Mach-E with a 35aH 12V AGM battery. Letting the camera run in parking mode and draw the battery to 11.8V would kill the battery. I had to build my own cut-off circuit to raise the cut-off to around 12.5V. An adjustable cut-off is something that should be included in the camera itself.

I’ve been using the 70mai A810 dash cam for several weeks now, and I’m genuinely impressed with the performance, especially considering the price point. If you’re looking for a reliable, high-resolution front-facing dash cam, the A810 should absolutely be on your radar. There are a couple of Pros: Crystal-Clear 4K Video: The Sony Starvis 2 sensor really shines here. Daytime video quality is extremely sharp, and license plates are easy to read even at a distance. This is a noticeable step up from typical 1080p cams. Excellent Night Vision: Low-light performance is surprisingly good—headlights and streetlights don’t blow out the image, and it maintains good detail in shadows. HDR Support: Helps balance exposure between bright skies and shaded road areas, so video looks natural and well-lit in a wide range of conditions. Smart Features: Voice control works decently, and the AI-based motion detection for parking surveillance is a great bonus. GPS & ADAS: Built-in GPS tracks speed and location. ADAS features like lane departure and forward collision warnings are a nice touch—helpful without being overly intrusive. Sleek Design: Low-profile and well-built; it doesn't obstruct your windshield view and feels like a premium device. App Integration: The 70mai app is straightforward, and connecting over Wi-Fi is relatively painless compared to some other dash cams I’ve tried.

The 70mai dash cam is really worth it! The video quality is crystal clear, especially at night. The mobile app is intuitive and easy to use, and downloading videos is very quick. The memory card works reliably, and loop recording ensures I never miss any event. Installation is simple and tidy, perfectly fitting my car. Very satisfied and would definitely recommend to friends.

I was shopping for "front+rear" dashcam and initially did not think this will become the "trial and error" experience for me. After getting some rear camera quality issues with top of the line WolfBox (returned) and then discovering totally unusable parking mode in VIOFO (high current draw in standby, returned), I watched half of YouTube and settled on 70mai A810. Please understand me well: I was not up to research project, I wanted to buy, install and be done... but given my prior experience in professional surveillance video market, I could not bend my mind into accepting first two brands limitations or quality concerns. A810 is not completely flawless in my assessment, yet it seems to be as close as it gets in the category of reasonably priced front+rear dashcams with Starvis2 sensors. Frontal 4K camera on A810 is flawless! Picture quality, dynamic range and motion fluidity are very very good. Rear camera is "OK", yet still very reasonable. The application for Android is the best from 3 brands I tested, yet I would not rate it as "great", more like "adequate". Still, it is usable and I see that programmers made their homework around optimizing control flow when connecting/disconnecting and getting around the recorded footage. If 80mai keeps improving it (which I greatly hope) - it may definitely get into "great" at some point. Now, some grievances. Installation is relatively straight-forward, but company hardware designers made some mistakes which could easily be avoided: - wires are quite thick, for no apparent reason (power cord caries 3 thin conductors, which would flow through half as thick cord easily, surprisingly rear camera cord is thinner, while likely having shielding to carry) - thick wires make for unnecessary hard to push between panels or next to roof-liner - rear camera cord made into right angle (very rightfully so!), yet power is straight USB-C (why?? it makes cord routing much harder!) - rear camera distance from the glass such that it's not trivial to get between the heater lines Software had its own set of issues: - I was not able to download SOME of fragments when bench-testing dashcam - I suspect this is happening around the "partial clip" recordings, as in-the-middle clips loaded fine to phone - Download speed over WiFi was abysmally slow: 2 minutes to download 1 minute clip I had the issue reported to manufacturer (not expecting much and preparing Amazon return), but it was promptly followed, they guided me through diagnostics download and informed next day that bug was identified and will be resolved in the next update. To me it sounded better than I expected and quite reasonable, especially considering that I can take SD card off and have my video-clips downloaded/merged on my PC. At this point, I decided that to compare to other two(highly review rated) brands I tried, I'm getting reasonably good hardware, tested work-around for the issue at hands and manufacturer who seem not to ignore customer concerns, so I decided it's a keeper. I hope not to get mistaken :)
