Problem is the smart cameras, like blackvue - thinkware well it is not the cameras with the best image quality, granted it is not garbage either but just cuz it say 4K and actually is true 4K ( lots of fake 4K cameras out there ) then it do not mean top of the line plate capture abilities.
I think it is agreed upon that in regard to IQ the cheaper viofo A129 duo pro ( or whatever it is named ) are a bit better than the 2 other, and it still have a few issues to deal with too.
Blackvue and thinkware also seem to go out of their way to make sure only their own memory cards work in their cameras,,,,, and that's just a scary approach.
Hit and run are also on the up here in Denmark, but i have never heard of anyone actually experiencing it.
But even with a camera, a plate capture are not a given thing, first of all you will want a fair amount of light, up here in Denmark with the normal winter weather ( cloudy ) getting a plate capture ( on easy to read EU plates ) are far from a sure thing.
And you also want speeds and angle of attack to not be too far from ideal.
As i understand from Rick the boss of Street Guardian ( AU brand of cameras ) then the AU plates are problematic also from all the stuff allowed on them, in EU you cant have any stuff on plates, must be white background with blackk letters, and any national code or so must be off to the left side of the plate, no wavy lines , no koalas or kangaroos or what ever crazy are allowed in AU.
Still you should get a dashcam in that Kia, any dashcam are better than no dashcam, but plate capture are still a major issue of all cameras, it is a good thing at night or in low light to see the plate yourself and call it out for the microphone to record, cuz your cameras probably dident catch it.
And 4K cameras due to having way more smaller pixels on a given sensor size are not as good as the same sensor size with larger pixels that form up a 1080p image.
The larger the pixel on the sensor are the better it is at capturing light when there are not much of it around, but the best low light 1080p sensors are still far from miracle makers.
