Plate capture are so hit and miss, and its that way with any dashcam i have ever used.
Some days i am amazed why the camera have not captured any plates or far less than i expected it would, and other days where i have been sure today surely i can not read any plates, and then i get a surprise as i can read a lot of them.
My confusion are at a level where a suspect the automatic of cameras some times select some unfortunate settings to use, though they can only change ISO value and exposure time.
But that's how i feel, and its the same with the most expensive i have used and the most cheap ones i have used.
Plate capture i always test on a highway, and this mean both i and the oncoming car drive at least 80 km/h
This are the sjdash first on a good day then a bad day in the rain, and to be honest i dident expect it to work like that on a grey rainy day.
And the sjdash are not some super secret killer hardware, pretty normal if you ask me, and i am also sure sjcams dont have some super firmware team that can do things other cant do.
Personally i dont give much for plate capture, but it is just one parameter i use to gauge what i feel about a new dashcam.
