Does 4K resolution really make a difference or it's not worth the hype?
Those giant EU plates will look good in any resolution
It's an easy way of checking that you've paid the appropriate taxes.Some countries i wonder why the bother to have plates on the cars in the first place.
In the USA you can get ankle braces just for refusing to sign a covid document:There are talks here that people infected with corona and apparently not self isolating are to be equipped with a ankle brace or even forcefully isolated.
Both things ( that people done isolate when they have been found infected, and some one can even come up with the idea of fitting people with GPS trackers or forcefully intern then ) are just out of this world in my ears.

Wow. Thank you sir for the professional explanation. I've learnt so much!If it is a real 4K camera, then it has 4x the number of pixels of 1080, which should mean 4x the detail, and that does make a big difference in good lighting or when stationary.
Most 4K cameras do not use 4x the bitrate so the improvement is rather less, some only use 1080 bitrates and then you only get 4x the detail if there is not much movement in the image, drive under trees and they only produce 1080 detail.
So the answer is, it depends on the quality of the camera, not so much on the resolution, and you need to check out the actual image quality before deciding on a specific camera.
For most people 2K is adequate for a dashcam, 1080 is a minimum, 4K is more than adequate.
The 4K cameras also tend to come with better sensors and processors, if I want to make a movie then I will always choose the footage from my 4K Viofo A129 Pro, but as an accident camera for all conditions, on average the 2K A119 V3 is the better camera.
Difference in resolution between Viofo A129 Duo (1080), A119 V3 (2K) & A129 Pro (4K), also shows the field of view differences:
Well said, sir. I think 4K is bit too early for me4K is slightly better in our devices but it doesn't yet fulfill all it's potential- that is still probably a couple years away. As I see it, the biggest problem is that to reach it's potential will require higher bitrates than the current crop of processors and common SD cards are capable of. Some of the best 4K cams of today do well enough if you can live with their limitations and faults, and those differ from cam to cam. For now, the 'sweet spot' seems to be 2K where it's capabilities can be better and more fully used given the processor and card limitations we have. 1080p has the advantage of being more fully developed and thus can give us all it's potential, especially in multi-channel cams. For most people it does well enough.
There is no advancement if someone does not try to achieve it, so these 'early' 4K efforts are good for us and will lead to greater things. Whether it's good enough now you have to decide for yourself.

You made a good point on the smaller pixels. That's actually one of my conerns about 4K tooLots of faked upscaled 4K cameras out there. So it really depends. There's a large section here on cameras not offering true 4k. True 4K will without a doubt offer superior daytime video to 1080P. Night time video will suffer since the smaller pixels let in less light for the light sensors to process. In this respect, 1080P on a good camera is superior to 4K. How much, I'm not sure, but I imagine there's no uniform answer.
