It’s true that security signs are able to deter intrusions in Kansas City
Various studies indicate that security signs work when looking at ways to deter an intrusion. The reasoning is that the burglar will notice the display and swiftly determine that your residence is way too risky. After all, why worry about security cameras and alarms when a intruder can pivot to a more vulnerable house down the road?
With that being said, the same research indicates that signage ranks fairly low as a deterrent to crime. A well-placed sign mostly dissuades novices, but seasoned criminals might want to find how much security is really protecting your home prior to deciding on a different target. Other devices, like outdoor video cameras, have greater success at thwarting prospective invaders.
