Yes, home security signs can deter intrusions in San Antonio
Many studies confirm that security signs are effective when attempting to deter an intrusion. The idea is that the thief will see the signage and quickly determine that your residence isn't worth the hassle. When it comes down to it, why worry about cameras and sensors when they can move onto an unprotected house somewhere else?
However, the same reports show that signage isn’t the strongest intrusion impediment. A well-placed sign mostly dissuades amateur thieves, but seasoned thieves may want to find how much security is really defending your house before moving on. Other devices, like cameras, have greater success at preventing an intrusion.
