Moved into a house w existing ring

Hi all Need some help. I have 4 cameras w motion flood lights and a doorbell (pic attached). 2 questions 1. Which version is the doorbell and how do I open it to get access to the qr code to transfer? Previous owners disconnected them from their account so at least that is done. 2. Do I need to do the same (open for code) with the flood lamps? 3 of them are installed 15 feet high! Thanks!
