Type of conduit box to use for a Ring doorbell + keyed entry
As requested : The type of box if only a ring type doorbell would be a Single gang Bell box. These can be found with 1" threaded holes and with the proper gasket and cover would be waterproof. If you have additional devices like the key switch a double gang Bell box would be my next choice. Make sure to plug any unused holes in the bell box, I use a little RTV or silicone sealer on the threads on the top of the box so water cannot get in if sitting level water will pool in the small depression and over time may get in to your electronics, this is why I take the extra step of sealing the threads
