Camera Upload question

Hi all, I’m considering getting Plex Pass to mainly help me create users for my server rather than let everyone use mine, and one feature that peaked my interest is the Camera upload. So how does that work, so on my iphone, would it actually upload the pictures straight to my home server, no matter where i am? Is there anyway for this to work through the plex web or PC app as well to do the same thing? When i’m on vacation, it would be nice to have remote backups of the pictures, but i use a DSLR for that, so having that option through the computer would be more ideal for me.
