Change stick up cam battery wifi to ethernet cable

I need to change my 4 stick up cam battery security cameras from wifi to ethernet wired but there isn’t enough ports on my home router. Is there a ring splitter box you can buy to connect to my router i.e. a splitter box so I can connect all my cams to it which the users one port on my router. I looked on the ring website but couldn’t find anything?

You just need an unmanaged Ethernet switch. Just do a search plenty online and cheap
