Excellent dash cam with outstanding video quality

DMMarch 13, 2026✓ Verified purchase

The media could not be loaded. First, this dash cam is a bit more expensive than many other cameras you’ll find here. There’s a reason for that. I’ve owned several different brands and models over the years with prices ranging from $50 to $300. The cheaper cams ranging from $50 to $150 cram in lots of bells and whistles but fall short when it comes to video quality, which is actually the most important part of a dash cam. They tend to upscale their video to 4k size, but they’re not true 4k, and once you experience higher end cameras you’ll realize that pretty quickly. The last $300 cam I bought, before I got the Arc 900, had very good video quality but reliability was lacking. At times it would overheat and the double sided adhesive would fail because the mount was too small for the weight of the camera. The Arc 900 has a decent size mount more than capable of keeping the camera on the windshield and not dangling from its wires. Another advantage is the ability to remove the camera from the mount if you ever decide to not leave the camera in the car. Connecting to the cameras WiFi is pretty straightforward. You hit the WiFi button on the screen and it generates a QR code. With the app open, you select connect, aim your phone at the code and it connects. Downloading recorded video takes about 15 to 20 seconds. There’s also road safety options that will alert you to a vehicle starting to move in front of you when stopped at a light. An alert when your stop light turns green is also nice. This works pretty consistently, even when 3 or 4 car lengths back. I did purchase the parking mode cable and that option works very well with motion detection and any movement or banging on the car. One thing the app does not have is the ability to view a map with your GPS information. The video will display your speed but not location when viewed in the app or when viewing downloaded video on your phone. It will display this information if you view it on your PC or MAC using Thinkwares computer software, which is free to download. So that information is there, it’s just not as convenient as being able to see it on the phone application. Overall this is a great, high quality reliable dash cam. Read more

Best dash cam company in the market

Dario PortilloDecember 31, 2025✓ Verified purchase

I've had many dash cams before and those don't come close to matching up to this quality or proformance. Thinkware definitely know what they're doing. Highly recommend this product. Worth the money! Read more

Missing connectivity...but worth it. So worth it

Gustavo AlfaroFebruary 25, 2026✓ Verified purchase

Man...I went round and round about 4 or 5 stars on this one. If I could do 4.5 I'd do that. 1 - installation isn't fully 100% explained AND you've got to get a fuse tap if you don't want to use the lighter adapter! They include the hardwired adapter but not a fuse tap. Full disclosure - I didn't do research on internal fuse box location before purchase. So when it came to uncovering that in my truck and then finding a fuse I just said "nope" and almost returned...until... Fix: There is another way! Use OBDII adapter from blackboxmycar. It works flawlessly. Made install a breeze once you figure out the route you wanna go with your cables. Disclaimer: I didn't buy from anyone other than blackboxmycar because I didn't want the error codes and I didn't want the other issues I read about online. I wanted simply power and ground and let the camera do the rest. 2 - connection is outlined in the "manual" but not really explained or settings explained. Fix: read the screen. It's pretty explanatory. If you can work a phone you can work the setup. Easy fix. 3 - getting the media from the card to the phone to the computer is not fully explained. Fix: I'm a techie so I just removed the camera from the windshield, pulled the card, put it in an adapter (not included) and downloaded to the computer. Done. Easy fix if you've got a card reader, adapter, and have the ability to download the stuff. All in all I like it. Once installed and cables hidden it's clean. I bought it because I drive a lifted truck and it's got bright lights regardless, but lifted, even when aimed, the lights cause some issues. So I tend to get a lot of tailgaters and angry people when driving around. I also tend to see a lot of people that do a lot of things that might be considered illegal on the road. Also...I don't trust anyone anymore. So I'm sure if I have to use it, it'll save my behind one day. Things I'd like to see changed - and realize I'm being nit-picky here: 1 - include a fuse tap or an OBDii adapter. I am not about to splice a set of wires into power, low power, and ground in tough to reach situations. Too much can go wrong. 2 - interactive manual online if possible. Youtube taught me some things before I bought but I fear some aren't doing the research I am before they buy. Those 2 things would take it from a 4.5 to a 5 and it'd probably be an unbeatable dashcam setup. I bought it due to multiple, multiple, multiple video comparison reviews and I'm cool with the purchase overall. I don't regret it in the least. I wish I had recorded the install so y'all could see how it actually goes while threading it all through A-pilar and to the back and with cable cleanup. I'm sure it will serve me well as long as I keep up with the updates and it doesn't die. Spend the money. Get this setup. Rock it out. Read more

Not what I expected

SkinnyMarch 16, 2026✓ Verified purchase

I had high hopes for this dash cam, wasn't easy to use and couldn't get the app connected to my phone. Couldn't view any footage of anything it recorded on the dash cam, when I tried; it would just say processing etc and i let it do this over night and still was processing. I returned it and brought a cheaper one that works well and conects to my phone. Read more
