Studies show security signs are able to deter intrusions in Sacramento
Various studies say security signs work when considering how to deter an intrusion. The logical explanation is that the prowler will see the signage and quickly determine that your property is way too risky. When it comes down to it, why stress over cameras and alarms when they can move onto a more vulnerable mark in another neighborhood?
However, the same research indicates that signage ranks fairly low as a deterrent to crime. A wisely situated sign mainly puts off less experienced prowlers, but professional thieves will want to see how much security is truly shielding your home before moving on. Other equipment, like outdoor video cameras, do a much better job keeping an intruder away.
