I use a Rove R2, which is set at 1080 resolution at 60 fps. This has a 150 degree field of view which is okay, but having a wider view is better. My previous cam was wider but the battery failed after a few years. The 60 fps is for better night viewing, and not using the higher resolution because it isn't much better on this cam.
I also have a Rexing 4k with 170 degree view, but it's too large to mount for now, however the 4k image is really good and that view angle is good. It also uses a supercapacitor instead of battery should that shouldn't fail over time. I didn't try it at night yet though. I would prefer to use the Rexing if I find a good location for it. My cam use is to put it just on/above the dashboard with the cable running down to my 12v socket. Not clean but not too noticable on my Toyota.
My preference would be to find a high res with wide angle that isn't too big. Need to check the night visibility on it too.
