It’s true that security signs can deter intrusions in Mesa
Various studies confirm that security signs work when looking at ways to deter an intrusion. The idea is that the burglar will see the display and instantly determine that your residence is way too risky. After all, why worry about surveillance systems and alarms when a burglar can pivot to an unprotected home somewhere else?
However, the same studies note that signage isn’t the strongest intrusion impediment. A smartly positioned sign mostly puts off amateur thieves, but professional criminals will want to see the extent of security that is actually protecting your home prior to looking the other way. Other components, like cameras, have greater success at keeping an intruder away.
