Reolink doorbell camera adapters for different horizontal and vertical angles. The supplied angle adapter has a horizontal degree angle of around 15º and 0º vertical. Depending on where your doorbell is attached to your wall, you might need a different angle. In my case, I created an adapter with 20º degrees horizontal and 20º degrees vertical that perfectly frames people on my door.

You can mount this printed model to the door (I used PETG) and then use the metal mounting plate to attach the reolink doorbell to the printed model. The mounting holes to the wall are 103mm apart with 6mm diameter as shown in this figure.

I plan to provide different angles to cover different orientations, if you have any special need let me know. I added a rectangular shape to the adapter in the figure to hide my old doorbell fixes on the wall.
