Hi, I’ve just joined and have only had the C200 for 2 days, so maybe not much help, but I see that, they always talk about 4 cameras viewed at a time, (then I think you scroll to see another 4, that’s looks like it, no 2 camera option, yes it would be nice, but I see it works in portrait mode only except when viewing the one camera full screen, so maybe because the images viewed for the camera are landscape it won’t view 2 , without chopping the image.
theres a bit more about 4 cameras on https://www.tp-link.com/uk/support/faq/2742/. Question 31
not ideal maybe but trying to view 4 on a iphone is not brilliant as so small, (iPad a bit better) I have only one camera as I’ve only just got it as a test, Good luck @Tande
