Video doorbell without existing doorbell

@john4ac8ea Are you referring to the chime box inside your home? The Video Doorbell Pro also requires a mechanical chime box as part of its setup (it is not compatible with digital chimes).

The chime box works as a resistor for the Video Doorbell Pro; without one, it could cause damage to your transformer or the doorbell itself.

Yes, I was referring to our old chime box. Your answer is helpful...thanks for the quick response.

But if you have no old chime box, what do you do?  Insert a resistor?  If so how many ohms and what is the suggested power rating in watts?

@middlejim The Video Doorbell Pro requires a mechanical chime box as part of its setup. If you do not have a pre-existing chime box, one would need to be installed.

@middlejim​ You can search up Ohmkat for Simplisafe doorbell pro. It eliminates the need for a chime connector or chime, but all you'll get notifications for sound or button press is on your phone.

Compatibility and Design: The OhmKat Video Doorbell Power Supply is specifically designed for the SimpliSafe Pro Smart Wi-Fi Video Doorbell. It provides a direct power source without requiring existing doorbell wiring or a mechanical chime, making installation simpler for homes without pre-existing setups

Better yet here's a link. Copy & paste in your broswer. Due diligence on your part to read on that website, check reviews and questions posted.

I think its one each per doorbell. If you read enough they may have a chime solution. ie; perhaps their wirless chime transmitter.

Ask questions at Ohmkat if reading isn't enough.
