Does the video doorbell wired need a resistor when wired directly to a transformer?
Hi @Lalo13. You can find the installation instructions for the Ring Video Doorbell Wired in our Help Center Article here. I’d recommend following those steps for the installation, as the Doorbell Wired is designed to replace an existing doorbell button and gets its power from the doorbell system. If you don’t have an existing doorbell button, you can power your Video Doorbell Wired directly using our Plug-in Adapter (2nd Generation). I hope this helps answer your questions regarding the installation of your Doorbell Wired.
