There is NO place safe anymore, and you are very wise to get a security system. I use ADT (actually, it used to be Brinks), and so far I've liked it ok, but I haven't been "tested," thank goodness. All my windows, as well as doors are covered. The only really weak point, I think, are the double doors in my bedroom, which, it seems to me, would be easy to kick open, if one really wanted to. So I intend to have burglar bars put up over them. Wasn't it nice when we could live without so many fears? Yeah.....
