Where does doorbell power come from?


Search results success, as doorbell power comes from standard house power, and is connected to a transformer. Caution against electric shock is advised when considering changing the transformer. Interest in this topic is increased with the availability of security camera doorbells from Nest, Ring and Arlo, etc. Some camera doorbells use batteries (which can be stolen), while other doorbell cameras use existing doorbell wires.  They usually require power delivering 16-24 VAC, and at least 10 VA.
