It’s true that security signs will deter intrusions in Austin
Many studies indicate that security signs are effective when attempting to deter an intrusion. The reasoning is that the thief will see the sign and swiftly determine that your home isn't worth the hassle. Ultimately, why stress over security cameras and sensors when they can hit a more vulnerable house somewhere else?
Nevertheless, the same studies note that signage ranks fairly low as a deterrent to crime. A well-placed sign primarily discourages amateur thieves, but veteran thieves may want to discover how much security is actually shielding your home prior to moving on. Other equipment, like security cameras, have greater success at preventing an intrusion.
