Can vouch for Viofo, I've had A129 Pro Duo for a few years and it's not let me down, great image quality, cost something like $300 or so, hardwired it myself, all pretty simple. The only thing that failed on it was the 3M adhesive on a particularly hot day this year.
VIOFO A129 Pro dual with circular polarizer and hard wire kit. Took about two hours to do a very clean install. Get a Samsung Pro Endurance SD card too.
6 years and 4 years in Arizona heat for my A119 V3 and A129 Pro Duo, respectively. Still going strong.
OP, [this post convinced me to get a VanTrue S1 Pro](https://www.reddit.com/r/dashcams/comments/1luh6dy/vantrue_s1_pro_max_is_the_probably_the_nicest_cam/), which is a dual 4k system. Only had it for about 4 months but I will say the app is way better than any other dashcam I’ve used.
I have a VIOFO A129 Pro Duo and after 3 years, it’s held up to the heat of Midwest summers and the frigid cold. That being said, the camera does get quite hot during the summer daytimes, but I also use parking mode so that doesn’t help.
+1 for Viofo, I have the A129 Pro Duo which saved my ass less 5 months after purchasing it when a lorry decided to hit me 🙄
Also purchased the A129 Plus Duo for our second car due to my experience with the Pro Duo, the quality is miles better than nextbase on both models

Top-tier video, reliable evidence, but app struggles.
