Will having CarPlay/Android Auto in my vehicle affect the use of the dash cam? No, it will not affect the dash cam's ability to record normally. 3. Why do the videos recorded by my dashcam have no sound? To protect user privacy, the audio recording feature is disabled by default.

When using it for the first time, simply power on the dashcam and follow the on-screen prompts to complete the "User Guide" to start recording. After the initial setup, the dashcam will automatically start recording whenever it is powered on. 5. Why is the video quality of my dashcam unclear? To ensure smoother video playback, the videos viewed on the App or the dashcam screen are compressed and do not represent the original video quality.

    • Best dash cam for the price, with minor setup frustrations
Size: A800S-1
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. ... show more

    • EXCELLENT PRODUCT AT A REASONABLE PRICE
Size: A800S-1
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. ... show more

As a dashcam, it works great, I deduct 1 star because I cant connect via wifi, password is stated to be 12345678, they may or may not be true, I just cant connect even if I do a factory reset so anytime I need to view footage, I have to remove the SD card and view it that way on my computer, cant figure out a way to watch on my cell phone but recordings are excellent and no other problems as of yet.

Review Image by Vitaly D.
Hey thereSo, I've been using this 70mai 4K Dash Cam Front and Rear with STARVIS, and let me tell you, it's been a game-changer for my daily drives. First off, the video quality is insane. The front camera shoots in 4K, and it's like having a mini movie studio strapped to your windshield. I can literally count the leaves on trees as I drive by. And at night? It's like the camera has night vision or something. Super clear, even when it's pitch black outside. The rear camera isn't quite as fancy, but it still does the job. It's like having eyes in the back of your head, you know? Now, I'm not exactly a tech wizard, but even I found it easy to set up and use. The app is pretty straightforward, and the screen on the camera itself is big enough that I don't need my reading glasses to see what's going on. Oh, and get this - it's got this cool parking mode. I parked in a sketchy area the other day, and it actually caught some guy eyeing my car. Nothing happened, but it was reassuring to know I had video evidence just in case. The best part it super affordable. I've seen dash cams that cost way more and don't even come close to this quality. Bottom line, if you're in the market for a dash cam, do yourself a favor and check this one out. It's like having a personal security guard for your car, minus the attitude and coffee breaks. Trust me, you won't regret it! ... show more

    • Requires SD card, NOT included. Updated review
Size: A800S-1
Update: Customer service reached out to me regarding this review. They pointed out that the ads clearly state an SD card is NOT included in the one I chose. And that an SD card IS needed. It was my mistake. Regardless, they sent me a free SD card. The communication from them through the whole process was fabulous. I really appreciate everything they did to make this right, even though they did nothing wrong. I HAVE IT UP AND RUNNING AND AM VERY HAPPY WITH IT! Original review: Requires an SD card to even get it connected. NO WHERE does it say that when purchasing or in any directions. Infuriating and frustrating. This should be spelled out. Can’t tell you how long I spent trouble shooting why I couldn’t connect the hot spot or get in to any set up mode whatsoever without first inserting an SD card. No where does it tell me to purchase an SD card separately. If it does not come with an SD card then it should work without one. ... show more

    • Great 4k dash cam with a good price and features
Size: A800S-1
This is a solid choice for a dashcam. We've had it installed on our Skoolie for about a year, traveling around the country and seeing the sights. We use the second camera to record the inside of the bus, and use footage for youtube and TikTok videos. The image quality is very high and the device itself is pretty intuitive to use. The automatic event detection sometimes triggers on harsh bumpy roads, but if you're in a regular car or pickup truck this is probably not going to be an issue. My advice if you're recording in the native 4k is to grab any interesting footage after every drive, even with the large sd card you're not going too far back in time! The night vision is pretty good and the built in speed and gps coordinates are super useful too! I added a few samples from driving around in Arizona under different conditions, judge the quality for yourself! ... show more
