Great question, @mcdunne100! For the most part, our devices are designed to be quickly and easily installed. As you know, when it comes to powering devices via wiring, there can be some additional steps needed.
The Video Doorbell Pro will operate on 16v to 24v of AC power, which is what most standard chime kits and low voltage transformers will provide. It is common for neighbors be able to connect wires at the door to the Doorbell Pro, install the Pro Power Kit in the Chime Kit, and complete a setup in the Ring app on the first try without anything further.
Of course, this is not always the case, and through completing many installs myself, I’ve put together this Hardwiring Checklist for the Doorbell Pro that includes any factors to consider and links to helpful resources.
