Yes, home security signs can deter intrusions in Chattanooga
Various studies indicate that security signs work when considering how to deter an intrusion. The logical explanation is that the prowler will notice the display and swiftly make the decision that your property is way too risky. Ultimately, why worry about cameras and sensors when they can pivot to a less protected house somewhere else?
However, the same reports show that signage ranks fairly low as a burglary deterrent. A smartly positioned sign mainly puts off amateur thieves, but professional crooks will want to discover how much security is actually protecting your house before looking the other way. Other devices, like cameras, do a much better job thwarting prospective invaders.
