It’s true that security signs are able to deter intrusions in Long Island
Numerous studies confirm that security signs are effective when considering how to deter an intrusion. The logical explanation is that the burglar will notice the sign and instantly decide that your home is way too risky. Ultimately, why get concerned about cameras and sensors when a burglar can move onto an unprotected mark in another neighborhood?
With that being said, the same research indicates that signage isn’t the most intimidating deterrent to crime. A smartly positioned sign mainly dissuades less experienced prowlers, but veteran criminals might want to find how much security is actually defending your home before moving on. Other components, like cameras, do a much better job thwarting prospective invaders.
