If you have the previous version of the Ring Video Doorbell and you would like to replace it with a Ring Video Doorbell 2, the included adapter plate will allow you to install it in the same location without having to drill new holes in your wall.
Note that you should setup your Ring Doorbell 2 in your Ring App before mounting it to your door. Click here for information on setting up your Ring Doorbell 2.
Once you have removed the original Ring doorbell and mounting plate, place the adapter plate with it's smaller side (or the beveled edge) facing the wall.
Note that this step is only used if you are wiring your Ring Doorbell 2.
Please note that the short screws are not the security screws used to fasten the Ring Doorbell 2 to the wall.
