70mai 4K Dash Cam Front and Rear with STARVIS, Built in 5GHz WiFi & GPS Car Camera, Super Night Vision, ADAS, 3'' IPS Screen, 24H Parking Mode, Time-Lapse, Loop Recording, Support 256GB Max (A800S)

I bought this back in August 2024 and have had zero issues with it since. It works exactly as promised. Setup was easy, and the quality is excellent.Pros:The 4K front and 1080p rear recording gives super clear footage, even at nightNight vision is solid.Comes with a 128GB SD card so I didn’t have to buy one separatelyApp connection is smooth and quick to download clipsGPS tracks location and speed, useful for road trips or insuranceParking mode is great peace of mind when leaving the car outsideCons:If you want 24/7 parking surveillance, you’ll need to buy the hardwire kit separatelyThe rear camera's cord was a bit long for my smaller car, but better long than shortThe design is compact and doesn’t block my view. I use the app every now and then to grab cool driving clips or just review trips. Totally recommend if you want a powerful and reliable dash cam.

Let me start off by saying that for the price, I love this dash cam. The video quality is awesome, even at night. I do most of my driving in the dark because of the hours I work at my job so even seeing some reviews saying the night video quality wasn’t the best, I disagree. Installation was straight forward. Clean your glass, stick it up there and hide the wires. It even comes with a small plastic crowbar to hide the wires with. It’s small so it doesn’t take up space on the windshield or the back window of my truck for the rear camera (which is about the size of my thumb) and the app is also pretty straight forward and easy to use once it’s set up.Now the gripes: the sensor that detects sudden motion is way too sensitive. It spends half of my drives in emergency recording mode because I hit a pothole or crossed over railroad tracks and it thinks I biffed it into something. And my truck has an extremely smooth ride for a pickup, which is something.The instructions were frustratingly vague and don’t cover half of what they should (i.e. how to navigate menus and set it up initially).The app is similar in getting it set up because it continually mentions bluetooth when it means wifi. You have to connect your phone to the wifi in the camera for it to set up and it repeatedly says to check the bluetooth connection in the troubleshooting section, which was frustrating because it had me looking for the wrong connection for 20 minutes after a 12 hour shift. So when it says bluetooth, it means wifi - Fair warning. But the app is easy to use once you’re past the setup and you can go back and check all your recordings whenever you want and see a live camera view and play with settings and all the things.Once it’s set up and operational, it functions simply and easily. The menus on the unit are easy to figure out and navigate and it’s user friendly (once you get past the relatively useless instructions). My advice is to use the instructions to get an idea and use common sense for the rest because if you have any common sense at all it’s easy to figure out without any instructions - they’ll just confuse you and slow down your installation and possibly have you muttering light cuss words under your breath.Overall it’s the best value I found, and it works well. I’m happy with it and living in Florida and seeing the way people drive down here (some of the things you see down here are WILD) it’s a solid investment. I would definitely recommend this to a friend.

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 Amazon. 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 Amazon) 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.

The product is well-built. It gets the job done. The instructions are pretty straight forward if you ignore some grammatical errors. Just like with most manuals, there are gray areas that you must use your imagination to navigate.I'm satisfied with the product, but I have to drop a star because the rear camera doesn't work very well with my car. My car has a rear sunshade that is automatic. Therefore, it jams on the camera when I reverse. It gets jammed and still somehow gets past the camera and closes completely. Sometimes it simply stops halfway, which is a bit frustrating. Finally I disconnected the rear camera and now only use the front camera. You wouldn't have this issue if your car is pretty basic and does not have such extra features.
