Is the intercom doorbell a property installation?

I don't understand you.

Even if it is not a visual intercom, the general intercom doorbell at home can open the door by pressing it.

Besides, why didn't you mention it when you closed the house? This is a developer's business, not a property's business, and the property will definitely not give you free installation.

What are the requirements when buying a house? Have visual intercom, seek development collectively. If not, install it yourself. General merchants will provide installation!
