Jennifer. Thanks for the response.
The answer I was looking for was they are all 850 nm. So, the only difference I see is the frame rate of the Doorbell 2 changes come night mode, whereas the Pro and Elite doorbells keep a constant frame rate.
I’ve ordered a Pro to replace my Ring 2 to see if this renders the 830 nm flooded area like my Elites do.
Thanks.
Steve
