Wait, are you saying that American homes did not have the regular camera doorbells before Ring happened? Those things predate LCDs. Earliest implementations date back to at least mid 1980s.

They would be uncommon for single family homes or duplexes unless built in last decade or so.
Audio intercom with shared entry door buzzer are common with older apartment complexes. Newer buildings and retrofits have video.
