It’s true that security signs will deter intrusions in Long Beach
Various studies indicate that security signs work when considering how to deter an intrusion. The logical explanation is that the thief will see the display and instantly make the decision that your property is a poor choice to target. Ultimately, why stress over surveillance systems and motion detectors when they can hit a more vulnerable home somewhere else?
With that being said, the same studies note that signage ranks fairly low as a burglary deterrent. A smartly positioned sign primarily discourages novices, but professional criminals will want to discover the level of security that is actually defending your property prior to looking the other way. Other components, like cameras, have greater success at thwarting prospective invaders.
