Hello everyone and I am asking you warmly.
After refurbishing the apartment, we also decided to replace the intercom camera. Unfortunately, the repair crew did not know how to connect it. And I was left alone with the problem. The case is as follows. In such a configuration as it is now, the door can be opened but the bell signal cannot be heard and it is not possible to talk to the control panel.
I am asking for advice
