Things work differently in different countries,
My condo complex has security 24 hours and at the gate there is a camera pointing at your car, even my cleaner has to show ID to get in, cameras are everywhere in the car parks, 1 underground the lobby area and in the corridors, obviously not in the unit,
Few guest do ask if we have secure parking, It seems most are happy with it,
Nobody can just walk in, they can only get so far after that they need a keycard, also stops people coming in and using the pool, the only people who can use the pool are people staying there, Keeps it very private.
