I'd like to be able to identify licenses plates as they enter our cul-de-sac. My question is triggered by a comparison between an Arlo Pro 4 and an iPhone 12. The iPhone produces extremely high quality images and I think acceptable for what I want. The Pro 4 produces poor images. I believe my iPhone has a 4K camera vs the Pro 4, which is a 2K.
I realize I'm not showing an exactly fair comparison. Both of these pictures were downsized to 1024 width and I tried to disable compression; dropped colors to 256 using Irfanview. Visually, these look similar to the originals, though.
Can you speculate on the reason for such poor image quality from the Pro 4? Would moving to a 4K model be sufficient? Because the field of view requirement is maybe 45 degrees am I thinking about things properly? For instance, would a 2K camera with a small field of view be better than the 2K with a ~150 degree field of view?
