Is there a good way to connect multiple POE ring cameras together?

Hi. I need to replace a POE/NVR camera system that still works, but is now obsolete. Looking at a Ring solution but don’t know how to hook multiple POE cameras together to one port on the router? I have cat5 cable already on my existing system that I’d like to use (they connect with an NVR that I want to eliminated and go cloud based). I’m not a techie and dont understand the ring elite “adapter” and cant plug in a dozen cameras to an outlet or router…Ring support has not been able to help. Hoping someone here can help and break it down to my novice level.
