VDB2 to VDB3 upgrade: to resistor or not...

I’m in the process of upgrading from the Video Doorbell2 to the Video Doorbell3.

Currently I’m hardwired 24ac with a 25 ohm 50w resistor (but the VDB2 isn’t charging so is being warrenty replaced…) and no other inline devices.

The Video Doorbell3 seens to conflict by saying in both needs 25ohm resistor and it doesn’t.

What is the correct answer?

Here says is needs it:

While here it says remove:

Resistors are not needed when hardwiring a Ring Video Doorbell 3 or Ring Video Doorbell 3 Plus.”

Hi @wrighar. Thank you for bringing this to our attention! I confirmed with my team that a resistor is not needed for the installation of the Video Doorbell 3 and 3 Plus. I’ve forwarded this information to the appropriate team to review so we can make sure that our Help Center Articles reflect that a resistor is not needed. I hope this clears things up! :slight_smile:
