It’s true that security signs are able to deter intrusions in Raleigh
Various studies confirm that security signs are a good idea when considering how to deter an intrusion. The logical explanation is that the prowler will see the signage and quickly make the decision that your home is a poor choice to target. After all, why worry about security cameras and alarms when they can pivot to a more vulnerable mark somewhere else?
With that being said, the same studies note that a security sign isn’t the most intimidating deterrent to crime. A well-placed sign primarily discourages amateur thieves, but veteran thieves may want to see the extent of security that is really shielding your house prior to looking the other way. Other devices, like outdoor video cameras, have greater success at keeping an intruder away.
