Whether or not you’ve noticed them yet
Burglars want to go unnoticed—and some will go as far as to test potential victims to see how attentive they are before breaking in.
A burglar might, for instance, leave a flyer outside your home to see if it gets picked up before striking—if it’s still there days later, that’s a good sign you’re not home.
Similarly, if they have access to your house, they may unscrew bulbs in a motion detector light or leave a door or window unlocked, hoping you won’t notice.
