Dahua IP intercom: VTO3211D-P2 (new P & P4 ) door station - experience, review, firmware support?
I purchased a VTO3211D-P2-S1. The Polish language was missing. Following the instructions, I updated to the latest version 2019-10-19 V4.400.0000000.3.R. The update was successful. Unfortunately, it turned out that I have one button available, how to activate the second button?- rekinowaty
