So many cams are based on the NT96660 processor, which results in fake 4K. The results are often less than stellar. The camera I used is the MGCool Explorer 1S (because it has pretty sharp video for Novatek). This is versus the ThiEYE T5e (real 4K). In order to get real 4K you need at least 8MP sensor, and many of these cams are advertised as 12, 14 or 16 but really have more like 4MP. This comparison shows a cam with a real 12 MP sensor. I’ll do another Novatek one with a 4MP cam later.
