Yes, home security signs are able to deter intrusions in Blacksburg
Various studies say security signs work when looking at ways to deter an intrusion. The idea is that the prowler will discover the display and instantly decide that your residence isn't worth the hassle. Ultimately, why get concerned about cameras and motion detectors when they can move onto an unprotected home in another neighborhood?
However, the same studies note that signage ranks fairly low as a deterrent to crime. A wisely situated sign mostly discourages amateur thieves, but professional thieves will want to see the level of security that is truly defending your property before deciding on a different target. Other components, like security cameras, are more effective at thwarting prospective invaders.
