Studies show security signs will deter intrusions in Baltimore
Many studies say security signs are a good idea when attempting to deter an intrusion. The reasoning is that the burglar will discover the signage and instantly make the decision that your residence is way too risky. Ultimately, why stress over security cameras and sensors when a intruder can hit a less protected home in another neighborhood?
With that being said, the same studies note that a security sign ranks fairly low as a burglary deterrent. A well-placed sign mostly dissuades amateur thieves, but professional criminals will want to see the level of security that is really shielding your home prior to looking the other way. Other components, like cameras, are more effective at thwarting prospective invaders.
