Watched a show once called it takes a thief. With two ex burglars on it. Two things they said were tops in deterring break instead were cameras/ visible home security signs and noisy dogs.
Thier reasoning was simple, why take the risk when there are hundreds of other, easier, less risky homes to break into.
When we are home we even lock the screen doors so they have to break through a locked outward opening door, outward opening being important to slow things down for those inside. And all windows including screen doors have a security film on them.
