Review: EXCELLENT PRODUCT AT A REASONABLE PRICE - Installation of the front camera, rear camera and hardwire kit in a RAM 3500 crew cab pickup took about 3 hours. All of the supplied cables were more than long enough to use in a vehicle that size. Getting the cameras up and running after installation was really straightforward. The picture quality, day and night, is excellent and I would buy the 70mai A800S again. That said, nothing is perfect and so I found things that need to be improved. #1 on the improvement list is the setup instructions. During setup the user is given several options. For instance, options for video length and options for how long the camera stays on when you exit the vehicle, however, the instructions give no information to help the user decide why you may want to choose one option over another for your particular situation/needs. #2 on the improvement list is the 70mai app. The app does allow you to connect to the A800S internal WiFi and it does a good job of allowing you to view video saved on the SD card. The issue I have with the app is that it takes way too many keystrokes to be able to view a saved video. It seems that every user command input simply brings up another warning window that the user has to clear to finally arrive at being able to view the saved video. A little information about video playback. On my first attempts to view recorded video from the SD card, both on my iPhone XR and on my laptop, the video quality was lacking. The video had a somewhat 'liquid' look to it, a sort of motion blur. The quality was good enough to show what happened leading to a traffic incident, but impossible to get any detail like a license plate number or road signs. I replaced the SD card with no improvement so I actually thought the camera was defective and requested a replacement from desertcart. Before the replacement arrived I found the answer to getting clean, crisp video from the SD card. I downloaded a VLC media player to my laptop and when I played the saved SD card camera video using the VLC player, BINGO, clear crisp HD video! I have now purchased a Lightning to SD card reader from Apple (about $30 on desertcart) and downloaded the VLC media player to my iPhone and iPad. If I want or need to view clear, crisp HD video I simply remove the SD card from the camera, insert in into the Apple card reader and play it through the VLC player on the phone or iPad.
Review: Good camera for everyday usage. - Easy to install, both front and rear cameras provide good quality both under clear light and in dim/dark conditions. Menu is easy to navigate. I cannot judge about camera's G-sensors' work, because camera is connected to the third party security system installed on a vehicle which turns cameras on and off based in its own sensors. What I dislike: you have to register in xiaomi site to use all features of mobile apps, also a lot of functionality is available only through wifi connection, so if your phone is connected to car's system using wifi (in my case it's Uconnect by Sellantis), then to download videos you need to disconnect the phone form the car and to reconnect to the camera. This makes things boring. As about ADAS and other systems installed on camera - I have tested them, and they seem working, though I keep them off as I do not need them. So overall impression is good camera with a lot of of optional functionality which may or may not be used.

### ⭐⭐⭐⭐⭐ The firmware update allows this to record events for days without killing my car battery
*by B***G on March 10, 2026*

Love this dash camera, especially after it received a firmware update for low power mode which allows it to record for days now. The quality of the video footage is a huge improvement over the unit in my other car with easily readable license plates even at night.
