Question about Ubiquiti UVC-G4-DoorBell

I googled "230V 16V" and got some results. That also works quite well. Just make sure it has enough amps (A). Better a little more than the same amount, so that the power supply doesn't have to work at over 50% straight away. It is always better if the quiescent current in the consumer does not load the power supply by more than 20%, then the whole thing will last longer and get less warm.

Then I would like to see a link like that.
I couldn't find anything using Google.
The standard is 12 or 24 volts
