It’s true that security signs are able to deter intrusions in Ventura
Various studies say security signs work when attempting to deter an intrusion. The logical explanation is that the burglar will see the signage and quickly make the decision that your property is way too risky. When it comes down to it, why stress over cameras and alarms when they can move onto an unprotected home down the road?
With that being said, the same studies note that a security sign isn’t the most intimidating burglary deterrent. A wisely situated sign mostly dissuades novices, but professional criminals might want to see the extent of security that is truly shielding your home before moving on. Other devices, like cameras, do a much better job thwarting prospective invaders.
