    High quality, easy to setup and use.

    I purchased this dashcam to replace an aging dashcam that was having issues. I have to say this was a huge step up in multiple ways!To start the picture quality is gorgeous. Every detail is crisp and easy to read. Keep this mind as you purchase a SD card since the files it makes are large I would recommend going with the highest it supports which at the time I saw 128gb, but apparently it does 256gb now. It looks fantastic both day and night, the quality doesn’t go away at night.For installation it uses a static cling sticker both on the front and back and then an adhesive to the sticker for t

    Good dashcam

    After looking for many dashcams, I decided to stick with the 70mai A810S. The first reason is its well-known brand. Secondly, it uses a supercapacitor instead of a lithium battery, which helps me worry-free about fire, especially in the heat in my place. The camera delivers exceptionally sharp 4K front and 1080P rear recordings that capture license plates and road details clearly, even at night. The Sony STARVIS 2 sensors and HDR technology significantly improve low-light performance, while built-in GPS accurately records speed and location for every trip. Installation was straightforward, the

    One of the best Entry Level 2-Channel STARVIS 2 Dual Sensor Dashcam

    First impressions: It comes in a sturdy, well-designed box. Inside, there is a pouch containing a 128GB microSD card (a fantastic bonus given current memory prices), along with window film and a manual. Beneath that layer, you will find the main camera unit, the rear camera, power and connecting cables, a car adapter, and a plastic trim tool.The built quality of the dashcam feels premium. Seems like it’s built to last, there are a lot of vent holes to help keep the unit cool as it runs throughout the season. It attaches to a mount that sticks to your windshield and you slide the dashcam up to

    Excellent images, wireless connection to phone app

    The video is AWESOME, day or night. I'm especially impressed by the nighttime resolution and clarity. I plan to decrease the frame rate to decrease the file sizes, because who needs 60 fps anyway?Installation required some common sense intuition. The mounting instructions have images but few words, which would be fine, but the various images were not consistent. Should the rear camera look through the electrostatic film, or around it? Different images were inconsistent on this, and there were no words saying which was right. I opted to mount so it looked around the film. The electrostatic film

    Pleased with the camera so far

    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

    Best Dash cam!!!

    I’ve been using the 70mai A810s 4K Dash Cam, and I’m genuinely impressed with its performance. The 4K video quality is incredibly sharp, making it easy to read license plates and road signs, even from a distance. Night recording is excellent as well, thanks to the Sony STARVIS 2 sensor and HDR, which produce clear footage with minimal glare.For the price, I honestly think it’s one of the best value 4K dash cams available. The combination of excellent video quality, reliable performance, and useful smart features makes it easy to recommend. If you’re looking for a dependable front and rear dash

    Good initial impression

    This is my first ever dash cam and first impressions are pretty good. Install was easy enough, I was able to get it working pretty quickly. I plugged it into an existing USB port on my car and routed the wires around to the plug. The back camera was also easy enough to install. I tucked the extra wiring into a panel where nobody knows it is there.I pulled the card to look at the video and it looks pretty clear both day and night. The rear isn't as clear, but it is also a lower resolution so that is expected. I don't see a way from the app to get a combined front/rear video but I can use extern

    USB C

    This one has a USB C port. All the other ones seem to have a mini USB port that is outdated from what I saw. I gave it four stars because I have the setting for it to shut off after 5 minutes when the car is idle but if you do that it won't turn on once you leave. I need something that detects when the car is in motion so that I won't have to turn it on manually. I put the setting to never shut off the screen now because anything can happen even when you're pulling off a supermarket parking lot.I got it to connect to my phone easily and I even updated it through the phone as well.
