You know I come from a wealthy family and my parents house they were living in back in 1993-1998 they had a nice alarm system, but they got so used to it being a safe area they never turned the alarm on. Than before you know it, 2 streets over a boy killed both his mom and dad. By than my parents were moving to the country, but if they had stayed I'm sure they were going to use their alarm every night.
We had an alarm system too and rarely used it.
