Resolution and HDR or not?

[N.T.]

I just got the camera and when I test it in my hand I feel it warm.

Considering this I am thinking which setting is optimum if I put it on the windshield.

First priority is to see car plate clearly, which is the major purpose of a carcam isn't it, but I don't want it overheat and stop working.

1. will it overheat if I set super fine quality and highest resolution? 90F (33C) would be the hottest usually in summer.

2. is 1296p the best or the 21:9 setting?

3. does the HDR setting better between those two 1920x1080? should I use it rather than higher resolution one?

4. should I choose smaller loop duration or 5min is good?

thanks!

smaller loop is better from a file management perspective

21:9 mode I think works best on these
