“security doors” are another example of security theatre. they add no value, it's another system to maintain and service and for many they just add inconvenience to the resident and their visitors getting in and out.
your typical security door might keep some 8 yr olds out, the bible bashers and electricity salesman and real estate agents, maybe, but for anyone else that wants in they're really very simple to defeat. just push the buttons until someone lets you in, usually works. failing that, follow a resident in, particularly at peak time for movements, mornings or afternoons.
The best security you cant see.
