It does when you want a clean clear video of an incident when its completely blurry or pixellated that you can't make a thing out....or at least the little details of it.....that you need or want for evidence....
We're not talking about cheap crappy cams like that here- at least I'm not. And TBH even my absolutely horrible G1W clone ($26 delivered!) did well enough to prove innocence even if it could barely get the plate number of a car stopped right in front of me in broad daylight Car placement and movement, lane markings, signage, traffic lights, taillights, brake lights, and turn signals were all displayed without any room for question. That's all you need to prove your innocence. Nice to have better though
You seem to just want to argue that all 1080p dashcams have crappy video when they don't Have a look at what Street Guardian does with their 1080p cams, better than some 2K and 4K cams get you Maybe you've only had a defective or junky cam to base your experiences on, I don't know, but I do know that the vast majority of dashcams in use right now are likely 1080p30, and most of their owners seem to be fairly happy with that level of performance. Given a good build with good FW and a decent bitrate 1080p30 can do quite well
As to FOV the difference between a 'box' measured diagonally versus horizontally should be easy to see or imagine; the diagonal will always be wider. While I think horizontal measurement is more meaningful for us, the industry standard for cameras is to measure diagonally so that;'s what we get. I've used a protractor to test many cams horizontal FOV and have found that even when allowing for the diagonal to be more, very few meet or even come close to their advertised value. It's well-known among experienced dashcammers to not believe those figures but instead to look at the videos and still-frames posted to see what you really get. That Garmin is certainly not close to 180 no matter what they claim. In fact few cams go past about 135 degrees diagonally in the vids you see from them with many popular ones doing more like 110- 120 degrees Still pretty good for our purposes no matter the claimed values being so inaccurate.
