These new systems are really great. Some of the new buildings that I just bought properties in will utilize this system. Some of the technology that is coming will be amazing. I own an apartment in Mexico where it's very high tech. You can't even use the elevators without having a scan of your face so it will immediately recognize you when you enter the building. I'm told this technology will be used in some of these screens as well.
@Sunny does your building utilize face recognition? Or QR codes? This will cut down quite a bit on expenses in buildings that had traditional security guards before.
