Thanks, Found online--Amazon I think for about $17--I'll check when I get back. Not sure since I had my son order some things for me.
Securityseeker, it does freeze where they live, but figured for that little $ I'd try it. (I actually had a couple buck stepdown transformers in the garage at home and would have used one of those if I had remembered it---they were only $6.80 for two decent quality adjustable ones on Amazon).
I had just one drop to that area and no other power easily available so I wanted to try inline switch. It draws power from POE switch and then feeds both the doorbell and another cam that is af/at POE. Everything is enclosed in a weatherproof security box in a pretty protected area from harsh weather. I'll see how it holds up.
No snow where I live and heading back there now---walking the beach tomorrow

Of course, our trade off is we have to keep an eye on the hurricanes.
I'm more interested in the indoor chime and electronic unlocking module now and may have to order some items and experiment. Probably going to use to control access thru that gate the cam is now pointing at.
