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.”
