Studies show security signs are able to deter intrusions in San Francisco
Various studies confirm that security signs work when looking at ways to deter an intrusion. The reasoning is that the burglar will discover the display and quickly decide that your home is a poor choice to target. After all, why stress over security cameras and alarms when a burglar can pivot to an unprotected mark somewhere else?
With that being said, the same reports show that a security sign isn’t the most intimidating deterrent to crime. A well-placed sign mainly puts off amateur thieves, but seasoned criminals may want to see how much security is actually defending your property before looking the other way. Other equipment, like outdoor video cameras, have greater success at keeping an intruder away.
