70mai A810 4K Dash Cam Front and Rear, Dual Dash Camera for Cars with Starvis 2 HDR Night Vision, 4G LTE Support, ADAS, Built in GPS & WiFi, 24/7 Parking Mode, AI Motion Detection, Time-Lapse

A Smart, Sharp, and Reliable Road CompanionAfter testing several dash cams over the years, the 70mai A810 4K Front and Rear Dash Cam stands out as a true gem. From the moment I installed it in my Cadillac XT4, I knew I’d found something special. Stunning 4K Footage That Doesn’t Miss a BeatThe front camera captures razor-sharp 4K video with HDR, making every detail—license plates, road signs, even raindrops—crystal clear. One rainy evening, a car cut me off dangerously. The A810 caught everything in perfect clarity, which made filing an insurance claim smooth and stress-free. Rear Cam + Parking Mode = Total Peace of MindA few days after installing the hardwire kit, the rear cam recorded someone bumping into my parked car and driving off. Thanks to the footage, I had the license plate and time stamp—no more mystery damage!Easy to Use, Even for Non-TechiesSetup was quick, and the app is intuitive. I love being able to download clips straight to my phone without fiddling with SD cards. GPS and Bluetooth are built-in, and the 3-inch screen is bright and responsive.

This was the most affordable camera I could find with the IMX678 sensor. It may not be the absolute best camera you could buy but I am taking price point into consideration when giving it 5 stars. The IMX678 sensor is key to getting clear true 4k resolution. Some cameras say they are 4k but use the IMX675 sensor then scale it up. Others do not even tell you what sensor they use and I would steer clear of those. I bought 2 such cameras before this one and returned them. The only thing that could really be better than this is if the rear camera was also 4k with an IMX678 but I would not expect that it this price point, that is going to cost you another $100. The 1080P rear camera is fine. The menus are easy to navigate, the app works well, the wifi/Bluetooth connect easily, and you do NOT have to have it connected to your phone at all times for it to work as somebody else said in their review. I tried to use a different brand of parking cable and it did not recognize it, you have to use the 70mai cable. This is no big deal, but I wish they had been more clear about that in the information. If you use the cigarette lighter plug and it receives power when the car is off, there is an option to have it automatically shut off so it does not kill your battery. Someone else was complaining it killed their battery and there is no reason for this if you know what you are doing. The same applies to the parking cable, if you don't know what you're doing leave it to someone who does so you don't kill your battery. Both cameras mounted well, even in the cold. the audio quality is fine I guess, wasn't really an important factor to me.

Outstanding Dash Cam – Packed with Premium Features!I've been using the 70mai A810 4K Dash Cam (Front and Rear) for a few weeks now, and I couldn’t be more impressed. The 4K front camera paired with the rear cam provides crystal-clear footage, both day and night. Thanks to the Sony Starvis2 HDR night vision, license plates and road signs are incredibly sharp even in low-light conditions.One of my favorite features is the 4G LTE support, which lets me check footage remotely and receive real-time alerts. It’s peace of mind, especially when I’m parked in unfamiliar places. The built-in GPS & Wi-Fi also make transferring files and tracking routes super easy.The ADAS (Advanced Driver Assistance System) is a game-changer—it gives helpful alerts for lane departure and potential collisions. I also really appreciate the 24/7 parking mode with AI motion detection. It automatically records any suspicious activity, and the time-lapse mode is great for conserving memory while still capturing everything.Installation was straightforward, and the companion app is user-friendly. Overall, this dash cam is a powerhouse—perfect for daily driving and long road trips alike. Highly recommended!!!!👏👏👏👏

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 linesSoftware 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 clipI 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 :)
