Intercom and Access Systems

[Ilan Rabinovitch]

What are folks using these days for intercom and access systems on multi-unit buildings? In single family homes without shared entrances Ring, Simplisafe, etc seem to be great options. But for 4+ unit buildings with common entrances the options seem more limited.  The options I'm finding either feel limited by modern standards (eg no video, no audit logs, no app to remote control) or aren't met for multi unit. 

What are you using that you like?
