I'm surprised how much I like this dashcam. I wanted an inexpensive dashcam that also had an inside the cabin camera as I may be doing rideshare during the day and wanted that for safety reasons. Installing with the suction cup mount has been very sturdy. That was a concern of mine since I live in the Desert and the heat can often loosen these types of mounts. It's been up for a couple days and in the sun as has stayed firmly on the windshield. The picture is clear and at 30fps it's very smooth. Definitely good to capture the events of an accident. I do wish I could be a tad sharper, but for t

We purchased a new 2024 Acura RDX with he Advance package. We wanted a dash cam that was easy to install and setup, easy to operate and did not require any monthly subscription. This model (D30S) fits our needs perfectly. We wanted a dash cam that could record the front and inside of the car. The camera size is small and does not obstruct the driver or passenger view. The image clarity is exceptional for us - we set it up for Dual Mode (2.5K front and 1080p inside recording). The physical installation was very simple for me (less than 10 minutes). I did wish the dash camera used a USB-C connec
Bought & used this camera for 4-5 months then it stopped working. Contacted the seller and they provided me with a new replacement camera without any problem, once I provided documentation to show it wasn't working. Its a great camera and I would purchase another COOAU camera in the future. Other than this one problem it has worked perfectly. Would highly recommend to others. Thank you COOAU for your great customer service!
I purchased this dash cam and the optional hard-wiring package - and was hoping that I could set it up myself. I am sure many people have but after reading through the directions I asked a mechanic to do the job. Without hardwiring, however, it is very simple to install. However, where I saw a problem was that my cigarette lighter port, that the dash cam would attach to for charging, was not direct wired to the battery (car is off, no battery connection) - I did not feel confident it would stay charged (but I am not a mechanic so I can't be sure that is the case). I did have to purchase an SD
EDIT 02-28-24: Just bought another one for my wife Lisa...She absolutely loves it as it works great to record the trails she goes in with her Jeep Wrangler!!!02-11-24:I just received the COOAU Dashcam D30S and so far it's performed exactly as stated...I installed it on my 2021 GMC Sierra, just to the left and slightly behind the rear view mirror, using using the GM taped mounting bracket. The suction cup mounting bracket seems to work well, however I wanted to use the lower profile one.I plugged the dash cam into the USB port instead of the 12v adapter port (GMC Sierra's 12v adapter port is al
First off used this product for years it was great loved it, but now I wouldn’t recommend it to my worst enemy. I had this review up on their app on Apple Store but doesn’t seem to matter so I’m putting here as well. Seems whenever you actually need the footage it’s gone or never recorded, like as you read it’ll just not record the entire minute around the event you needed to have captured it has happened over 200 times at least for me just hoping it actually catches the big one versus the close calls.Update(6-20-2025) used it a while longer still trash but seems whenever I almost have an acci
I upgraded from my previous dash cam, because a state trooper gave me a ticket for not having my seatbelt on, even though I did have it on. I'm so glad that I got this one. It's very crisp, and that's exactly what I needed to do. And the section cup stays in place. No matter the heat, even though it is over a hundred degrees here, every single day.
The device itself meets the expectations I had when purchasing. It is compact and light weight. The suction mount works great and makes it easy to place and remove for storage. The app is disappointing. In order to connect your phone to the camera it requires creating a WiFi network. Frequently on opening the app I find that the log in has expired, which is irritating. Also when trying to view or download videos on the app, the camera will disconnect from the phone, and will not connect again until the camera is shut off and turned on again. Overall, I think the device is well worth the money
