Yes, home security signs will deter intrusions in Chicago
Various studies indicate that security signs are effective when considering how to deter an intrusion. The idea is that the burglar will see the signage and instantly decide that your residence is way too risky. After all, why worry about security cameras and sensors when they can hit an unprotected home somewhere else?
However, the same research indicates that signage isn’t the strongest intrusion impediment. A wisely situated sign mainly dissuades amateur thieves, but professional crooks might want to discover how much security is actually protecting your home before deciding on a different target. Other equipment, like security cameras, do a much better job keeping an intruder away.
