Yes, home security signs are able to deter intrusions in Orange County
Numerous studies say security signs are effective when considering how to deter an intrusion. The idea is that the burglar will discover the sign and quickly decide that your residence isn't worth the hassle. After all, why worry about surveillance systems and alarms when they can hit a more vulnerable house down the road?
However, the same studies note that a security sign isn’t the most intimidating intrusion impediment. A well-placed sign primarily discourages amateur thieves, but professional crooks might want to find how much security is actually defending your home prior to deciding on a different target. Other devices, like cameras, do a much better job preventing an intrusion.
