The real thing is to make your property less of a target.

Don't post on FB you are leaving on such and such a date.
Don't put your name on your mailbox.
Don't post images from inside your home of your exit doors.
Don't leave shovels, rakes, hoes, brooms, around your door, outside.
Don't put the garbage cardboard from your new TV at the curb.
Don't leave your garage remote in your vehicle, if that vehicle is never parked in the garage.
If you have an attached garage, secure your tools. why give them access to anything that can get them past your inside door.
Re-inforce your door jams, buy a decent lock with a long throw, or have a locksmith come by and up date your lock sets and hardware. Replace door glass with Lexan, or add a layer of Lexan to the window opening.

Window bars on basement windows are great. But they must be able to open, from the inside, in case of a emergency. Some times even metal slat window blinds will stop some one as metal blinds are noisy.

The punks looking for quick money do not really care if your home has an alarm or not. When the alarm goes off, he now knows he has 7 minutes to smash and grab.

If someone breaks in and only takes your pinball machines or targeted that floor safe in your walk in closet. Those people were prepared, and knew of those items before hand.

Years ago the next door neighbour told us that his house was robbed. He and his family had gone away for a long weekend, which is something they always did. One time they came home to a broken door and an empty house. Fake movers came by boxed all of their stuff up, then loaded their large moving van. Did not live next to them at the time, but a neighbour took a couple of photos. The guys had coveralls and all of the right equipment. Stolen plates on the truck as well.
