It’s true that security signs will deter intrusions in Tucson
Various studies say security signs are effective when looking at ways to deter an intrusion. The logical explanation is that the prowler will discover the sign and instantly determine that your home is way too risky. After all, why stress over cameras and motion detectors when a burglar can move onto an unprotected home somewhere else?
However, the same research indicates that signage ranks fairly low as a burglary deterrent. A well-placed sign mainly puts off novices, but professional thieves may want to find the level of security that is really protecting your house prior to deciding on a different target. Other components, like security cameras, do a much better job thwarting prospective invaders.
