I wonder how much actual 4K dashcam price would be. Many years ago when 1080p came on dashcams, most of them was upscaled from lower resolution. Same thing with 2K and now with 4K. Here is some nice extra info: The list of shame fake 4K dash cameras Ultra HD | DashCamTalk Edit: for example it says on Amazon page Rexit V1 3rd gen uses OV4689 sensor. That is 4MP CMOS sensor. 8MP is needed for real 4K. I really dislike that these kind a stuff are false marketed as they are upscaled so often.
