Studies show security signs are able to deter intrusions in Manhattan
Numerous studies confirm that security signs are a good idea when attempting to deter an intrusion. The idea is that the thief will notice the display and quickly determine that your residence is way too risky. When it comes down to it, why get concerned about surveillance systems and sensors when they can hit a more vulnerable home down the road?
With that being said, the same reports show that signage isn’t the strongest intrusion impediment. A wisely situated sign mainly discourages less experienced prowlers, but professional thieves may want to find the level of security that is really defending your property before moving on. Other components, like security cameras, have greater success at keeping an intruder away.
