Well, i live on the outskirts of a town of over 100,000. I have 3 sets of french doors and 2 normal doors all of which are secured with 5 lever locks.

When we moved in we didn't get around to figuring out the alarm system right away and promptly got burgled while we were asleep, lol.

We set the alarm now!! Of course it would have helped if we hadn't left the downstairs window open too, lol.
