Another vote for VIOFO A129 Plus Duo. We're well into our second summer with it, and haven't had any issues at all.
Owner reviews for dash cam
I have the VIOFO A129 Plus Duo and have been very happy with it. I stuck mine to the windshield and rear window with the included 3M double-sided tape and it has not come loose.
I've had a Thinkware F800 dash cam and rear cam on my windshield for 4 years and it still works perfectly. I just have it connect to the aux power outlet and used the sticky mount it comes with.
I have the VIOFO A129 in two cars. It has worked for me so far. One of those cameras is going through its second summer, and is still working.
I finally have my dashcam installed today! What I did is pretty much what Jadar did here except I didn't open the A-pillar trim. It was too intimidating to me. So I modded the USB cable instead: I replaced the middle part of the USB cable with 22 gauge 2 pin wire I bought from Amazon. This size of cable can be pushed between A pillar and windshield very easily (with the help of a trim removal tool). I also didn't buy a factory hard wire cable. And instead I used a 12v to 5v buck converter that draws power 12v battery and outputs with a USB type A female port. The dashcam of my choice is viofo t130 so I get both the front view and interior view in a very small body.
Another one here with a Garmin Mini 2 its sooooo small that it fits right behind the mirror in the miata. It's perfect for what I need.
I have a few. The two models are the VIOFO A129 Pro dual and Thinkware U1000. I prefer the Thinkware. The plug layout on the VIOFO is annoying and I feel that the app for Thinkware works better.
I run the Viofo A129 front and back. It's a solid cam. I got it because It has the super capacitor instead of a battery.
Here's an update on why I posted this thread. I have a Thinkware F750 Dashcam w/ the Hard wiring accessory so I can record (in parking mode) with the engine off but the cam fires up as soon as I turn the ignition and will record full time.
Blackvue 900, 2 channel; also had one in my 996 that was totaled when it was rear-ended by a perpetrator who was running from police. When I retrieved the mini SD to pull the video I discovered that the rear channel had failed some time previously.
