Unless you put huge bars over your windows and have a reinforced door frame/door/lock, it takes all of 30 seconds to break your way into a home anyway. Deadbolts are false security, even if electronic.
And a system where A) you give everyone the same 2 character password B) you don't give anyone a username and C) anyone can give anyone else admin credentials with no authentication?
False security? In what way? False as in they don't do anything? Or false in that they give you a false sense of security?
Deadbolts prevent the most casual of crime and crime of opportunity. Which I would argue is probably the most prevalent type of crime.
