Annke C1200 datasheet has 12MP (4096*3072) but hikvision camera "alternative" (
5.8.5_250714 (hikvision) for DS-2CD1363G2) has 6MP and the firmware max resolution is 3840x2160... so C1200 has a real 12MP sensor? because I don't see many differences in image quality between the Hikvision firmware (limited 3840x2160) and the original Annke firmware (4096x3072) and according to the datasheet there should be some but I'm not a video expert.
I've been looking for a 12MP Hikvision camera to find a more compatible firmware for the Annke C1200 and I haven't found it, and it seems strange to me that Annke has a better camera than Hikvision.
