I use the Viofo A139 2 channel for all of my cars and never had an issue with it besides the one time I bent the coaxial cable running to the rear camera disconnecting it. Tiny unit but captures very well.

It’s been \~2 years but I’ve been super happy with my Viofo A139A…supposedly has a better CCD than the rest or something, but easy install & clean images = an endorsement

VIOFO A139 2ch.   I have the rear camera mounted to the horizontal bar behind the seats.  It's great as I can rotate it to point forward when I'm at the track.  Fantastic quality as well

Yes. It is 2 channel dashcam, so it has one primary camera with all the main hardware and then a secondary camera that is connected to that first camera that can be put wherever. The first camera I have mounted to the windshield behind the rearview mirror and second on the horizontal bar. You can look in my profile to see a video I posted of one of my previous track days to see how it looks. I bought the hardwire kit for my dashcam and then used fuse taps to tap into the constant power and accessory power in the fusebox that is in the passenger footwell. The dashcam itself has a lot of settings to minimize a large power draw such as only recording when motion is detected. The hardwire kit also has a device internally that ensures the power is cut to the dashcam if the battery voltage starts to get too low.

I second that. Viofo A139 duo. But there are better versions out now I think.

AZDome M300S 2 channel heb ik op ali voor een €65 gekocht en het werkt uitstekend. Beeld kwaliteit is ook heel goed. Dit komende van een Blackvue 750s. In mijn ander voertuig heb ik een VIOFO A139 en dat is ook een goede cam, albeit een pak duurder
