Unfamiliar people on the street

Burglars frequently target many residences at the same time. A burglar doesn't have to look long to figure out which homes have people coming and going, which homes are unoccupied, and which homes have security systems. Of course, not every stranger on your block will be a thief. Strangers traveling up and down the block several times, seemingly for no other reason than to gaze at the houses, is a more suspicious behavior to notice. It's a major red flag if you witness the same stranger doing this discreetly many times.

A burglar may park down the street and then go about the area looking for the perfect house to break into. The suspect will be walking in a relaxed manner as if he or she were just strolling through the area. There will, however, be two major differences.

First, you don’t know this person. Second, every house they pass will be scrutinized by this stranger. Their gaze will first be drawn to the driveway, where they will check to see if there are any cars parked there. The visitor will then examine the house's windows to check if there is any movement. It's likely that you've caught a burglar-casing property if you spot a stranger examining too carefully the residences in the neighborhood.
