Ring thinks of almost everything to help the user. There are several sizes of screws supplied, depending what your junction box has. They even supply the screw driver with a removable shaft with a Philips head on one end and a flat edge on the other. Remove the shaft and you can use the handle to tighten the two finishing nuts. What impressed me was that the housing has a strap attached with a hook, this attaches to a hook on the mounting plate so you can leave the housing hanging while you connect the wires. The Ring app takes care of the configuration. Now I have a very clear view of my backyard, better lights than before and 2 way audio (good to have if you have people for a BBQ and you’re in the kitchen) This is not my first Ring device, I have the doorbell, the alarm system and several cameras and they all come with the same thoughtfulness.
