I hope you let the word "typically" do some stretching before you used it, because it's doing a lot of heavy lifting there. You have no idea what algo was used by each system. Assuming some landlord is going to install the top of the line equipment using the most advanced software with these algos that "work great on all populations" is just so generous that I want to see take advantage of that generosity.
Facial recognition is at best a parlor game. Yes, it can be super helpful for personal use in sorting through your own private library. If facial rec messes up in that situation, no harm is committed. When someone is denied access to their building, harm is committed. When someone is mis-identified and arrest warrants issued on an innocent person, harm is committed. To even begin to think that facial recognition is bullet proof in all instances is just folly.
