I am confused. I already have a few wired ring cameras that fit on my garden wall and are plugged into my mains socket. I want to add another camera to my system but they have all changed since I bought my last camera. There is the Ring Spotlight Cam Plus, the Ring Spotlight Cam Pro Wired and so on. I understand there are 4 different cameras? I want the same as my old camera. I want it for outdoors and plugs into a 3 pin uk plug socket. Which one do I need? I am so confused by all the new names and models.
