ring doorbell 2 help power supply

good ,

ring doorbell 2 can only be fed between 8 to 24 vac ?

or can be powered at 12V DC ?

I have another question, how does ring doorbell 2 connect to an existing doorbell?

is that I saw a video on how to connect to an existing doorbell and I didn’t understand it very well.

they only connected two wires to the ring

those two wires are that ?

Hi @pedroborges. The Video Doorbell 2 is not compatible with DC power, so it requires a transformer with a voltage of 8-24 VAC. You can find steps on how to physically install your Video Doorbell 2 with an existing doorbell in our Help Center Article here. The two wires you see are the doorbell wires that are already there behind your existing doorbell. I hope that helps! :slight_smile:
