Yes, home security signs can deter intrusions in Pittsburgh
Various studies indicate that security signs are effective when looking at ways to deter an intrusion. The reasoning is that the thief will discover the sign and instantly make the decision that your home isn't worth the hassle. After all, why stress over cameras and alarms when a thief can move onto a less protected mark down the road?
With that being said, the same research indicates that a security sign isn’t the strongest intrusion impediment. A wisely situated sign mostly puts off less experienced prowlers, but veteran criminals may want to discover how much security is truly protecting your house before looking the other way. Other devices, like cameras, are more effective at thwarting prospective invaders.
