Good for the price
It was very easy to install both front and back. I was successfully able to connect to the dash cam WiFi. I waited around 2 weeks to install the back camera as I didnโt have time to and once I did, it took me a while to figure out how to see the back camera footage. I clicked on the power button on the front camera and I couldnโt see the back camera footage. My issue was it wasnโt completely plugged into the front camera lol. Once it was, I was able to switch views on the camera. As for the app, it was very easy to use and it does have a membership that you can pay but honestly you donโt really need it since you can already download videos, take a picture, and see the front and back camera on it WITHOUT the subscription. It comes with stickers to stick the camera to your windshield as well as the back camera so you donโt need to drill it to your car. You can also turn audio on and off and I believe I saw that you can add music to a video if you wish to. Overall I like the camera quality in the daytime and nighttime, installation was easy, app works like itโs supposed to and itโs worth your money! (Also the camera turns on by itself and connects to your phone as long as your WiFi is on so I donโt need to worry about turning it on if Iโm in a rush).

Great Camera Nice App Great Quality Images & Video
I purchased 3 Chortau B-T13 cameras for the cars back in 2022 and for the most part was very pleased. And now I've purchased this one. There are a few things that stick out that I like much more about this camera than the others, but again the original purchase was very good. This one I like that they incorporated an app for downloading pictures to your phone rather than changing up the memory stick and downloading. I have had no issues doing that on the first attempt. Another thing I like about this camera is the quality of the video and pictures is much sharper with a wider visual frame. The wider visual is important to pick-up all the details in the surrounding area if needed. I also like the fact the camera is less obtrusive in the windshield. The fact that the screen is smaller is actually much better given less distractions and it isn't like you'd be looking at it while driving, this is what the pictures and video are for if needed. Finally what was much better was getting rid of the suction cup. Because it can get hot and the camera should not be in excessive heat I always had to either reconnect the cup which worked and sometimes didn't (if you look above second picture you can see I tried to create a better securing with the cup but that really didn't help). So in and out of the car unscrew the camera then screw back in. With this camera it is a quick slide to one side and you're out. This was a very welcomed engineer change to the mounting of the camera. So far absolutely no complaints on the mounting, camera, quality of pictures and ease of use on the app. Great product.

Stunning quality and easy to install
I really like this dash camera. It was super easy to install and hides very well behind the rearview mirror. The cable running to the rear camera was very easy to tuck away in my F250. Connecting the camera to the app through wifi went smoothly and videos transferred very well too and at high quality. I have had a few dash cameras in various vehicles and I am really liking this one. It is very high quality at a reasonable price.

It's works good..Just one problem
So far, this camera works pretty good and not bad for the value. I did purchase this at a sale price. Installing the front camera was pretty simple. Tucking the wires was easy except up through the windshield was tight were the airbags are at. The rear camera took a little more time and effort. Being that I have a jeep cherokee witha hatchback, it was hard to figure out where and how to mount it. Running and tucking the wire wasn't too bad. Again, running it up the windshield was difficult and I ran out of wire, so I had to reposition the front camera over towards the passenger side more, but got it done. Overall, a good setup, however, the biggest flaw when using the wifi connection to the phone, it disables the 5G connection and the wifi to and from the camera gives no internet access. According to support, this is a common problem, especially with Android phones. The only way around it, is to disconnect the wifi from the camera, then you won't be able to download videos or see the camera screens from your phone. It's a really stupid setup and o wish it was better engineered. Support assured me, the camera continues to record videos and to just turn wifi on from the phone to access the videos and download them.

It is a Good value for what you pay
I needed a Dash Cam because my previous one was too old and no longer records timestamps. I bought this one because of the form factor, which doesn't take up too much space. It seems like most dash cams come with the rear camera as well. See the pictures for what all it comes with, but I only use the dash cam, very standard and easy to run the wire. The wires are long. Oh, one nice thing, it comes with a free 64Gb SD Card, they include a bunch in the kit for sub 50 dollars. I will say before you take it out to attach to your car, you do need to install the app to change the settings to ur liking, such as the looptime, on default it was 1 minute. Also, the app will autosync the time for timestamps; the camera itself doesn't have any buttons to adjust settings, which is a bit of a downside, because it forces you to use the app, but I just personally like having the options to manually adjust it without the app. I pulled some footage from the SD Card to check, and the image quality and colors are good; it is 4K. The small Screen looks better than the image; it is just my phone creating a glare. It's good for what you pay for it.

Lock Button does not work/ Slow working app
This camera offers good quality and sound for its price range. After using it for a few weeks, I am generally satisfied. However, I have encountered an issue where the camera does not lock videos when I press the lock button. This is concerning, as the ability to lock videos is crucial for preserving evidence in case of an accident. The app is functional, but advanced features require a subscription. Additionally, I sometimes experience difficulties connecting to the camera via Wi-Fi, and downloading footage can be slow. Viewing footage without downloading is not feasible.

Broke in less than two months. No refund.
Update 1/3/2026 This thing was working great, then it just stopped mid December. I really wanted this to be a great deal. The camera will come on when it gets power, but not interface starts. It will show video for about 15 seconds then begin cycling power. I did try this with a good external power source with no luck. Whatโs more concerning is Amazons response. This was only eligible for a 30 day return. When I attempted to reach out to the seller, Amazon basically blocked my attempts to send them an email for warranty information. When I finally was given an opportunity to contact them it was a message through the Amazon system not a normal email. Did they get my message? Itโs been a week with no response. Probably not. But I donโt know. The fact that this isnโt available less than three months after my purchase says volumes. I hope this is not a sign of things to come with Amazon. Donโt buy it. Pay a little more and get a warranty. OK. The camera is good especially for the price. The app it uses takes a minute to understand and connect to the camera. Note if you buy this you will need to turn off your cell data and any VPN services before it will connect. Where thatโs a problem is you donโt have access to your cell if you use the app while driving. It doesnโt appear to have parking monitoring. I looked through the menus and the documentation and there is no feature listed. Which kinda sucks but for the price itโs not a deal breaker. The video quality is pretty clear both day and night. Over all the camera was easy to install the wiring takes some effort. While it does come with a rear camera, you must mount it in the rear of the car v its part of the main unit that faces backwards. It did come with a 64Gb SD card which was nice. For the price I expected a 32gb card. Overall I recommend it if you donโt need parking monitoring. Update: Apparently it does have parking monitoring if it has a constant power supply. I did not know what to get, but I have a friend who's an installer. He recommended https://www.amazon.com/gp/product/B0CPF6WNP1?smid=A86AD06S3OMVQ&th=1 this inline fuse link. It's fairly simple to install. Find a fuse that has a constant power supply and pull the fuse, then install the wire connection into the fuse slot, then install the fuse in the connector. Then run your wires. It comes with a voltage reducer so you won't damage your camera. After using this for about a week, there are a few things. If you need to perform a mass download of all your footage, take out the SD card and copy the files over on your computer. Yes, you can download them over the Wi-Fi connection, but most of the 4k three-minute files average ~450Mbs each. It takes several minutes for one. Also, your computer may not recognize the .ts format. If that is the case, simply download Gimp to view and edit the files on your PC. Would I buy it again. I would do more research on dashcams. For the price and what I need if for, it is well worth the money. The video and pictures are very clear and can be edited into much larger length video. But there are additional functions that would be helpful such as lane detection, object avoidance, GPS and maps that correspond to your video that would be helpful. If your current entertainment system has these capabilities, then and you only need the video and pictures, then this is a great camera for a great price. Also, there is a rear camera that comes with this unit. It does work, and it does provide some very clear footage. But it does not record if your front camera is recording. Further if you are in the app watching the video as it is being recorded, and you flip to the rear camera, it does not change the recording to the rear. I only say this for those of you who may drive in city or suburban settings where having someone following too close may need to be recorded. There is an option to switch it on the camera to the rear, I have not tried that option just yet. I will update this function once I have more information. The last note for this update. I still don't know how large of an SC card this can take. It shipped to me with a 64GB card. There was nothing in the documentation that stated the limit. It's still a good camera. And I still recommend it. As promised. Update. Total men is 256GB. Parking works when you have a constant power kit. It is not continuous recording in parking mode. It records in 1, 2, and 3 second increments. Still recommend.

Very easy to use
I recently purchased this dual dash cam, and it has exceeded all my expectations! The installation was straightforward, and both the front and rear cameras provide crystal-clear video quality, even in low light conditions. The wide-angle lenses capture a comprehensive view of the road, which gives me peace of mind knowing that every detail is recorded. One of the best features is the loop recording, ensuring I never run out of space, and the built-in G-sensor automatically locks any important footage in case of an incident. The parking mode is also a huge bonus, as it keeps an eye on my car even when Iโm not around. Overall, this dash cam is a fantastic investment for safety and security on the road. I highly recommend it to anyone looking for a reliable, high-quality dual dash cam!

Doesn't ACTUALLY Record everything...Which is the whole point of a dash cam
THIS PRODUCT IS AWFUL! I recently got into a car accident, and for some reason, the camera only recorded the back, and it's fully impossible t recover the full video footage without seeking professional service. When buying a camera, it should record 24/7 365 and all footage made accessible. Funny how this product is not available; nobody else would have to go through the hassle I have gone through with this.

Clear picture and Night vision
Somebody hit my car few weeks ago in the parking lot and I don't know who it was. I bought this 4K Dashcam to be safe. The instructions were little bit ambiguous but the camera is great and the cable length for rear camera is also more than enough.
