Glue down a fake spare key
This person didn’t have any burglary experience, but he did have a fun time messing with burglars. He glued down a fake spare key under the doormat and had security cameras pointed at it. Over the course of several nights, the camera picked up footage of potential burglars trying to get at the key and failing.
Instead of looking for alternate routes into the home, the would-be burglar would leave the scene immediately. There’s something about being tricked that a person on high alert. Use this to your advantage by setting up decoy objects around your home. A security camera would also be a smart investment.
