Yes, home security signs will deter intrusions in Harrisburg
Many studies indicate that security signs are a good idea when considering how to deter an intrusion. The idea is that the thief will notice the signage and instantly determine that your property is a poor choice to target. After all, why get concerned about cameras and sensors when a thief can pivot to a more vulnerable house somewhere else?
With that being said, the same reports show that a security sign ranks fairly low as a burglary deterrent. A wisely situated sign primarily puts off less experienced prowlers, but veteran thieves may want to find the extent of security that is really defending your house before moving on. Other equipment, like cameras, do a much better job thwarting prospective invaders.
