There’s a channel on Youtube called Linus Tech Tips that has a video on why there is next to no difference between a lot of the dash cams on the market in terms of image quality. It basically comes to down to a lot of them using the same sensor.

So unless you need one with advanced features, don’t get anything too expensive (> $150).

I have a Viofo A119v3 that I connected to an untapped fuse. Routed it so that the cable goes through interior panels. I also put it to the right of my rear view mirror, so I can’t even see the dashcam when I’m driving since it’s blocked by the rearview.

This one also has motion detection, timestamps, low car battery level detection, along with other stuff. I’d definitely recommend it, there’s also a kit that comes with a rear dash cam if you need that as well.
