Yes, home security signs will deter intrusions in Helena
Various studies say security signs are effective when attempting to deter an intrusion. The logical explanation is that the prowler will discover the sign and instantly make the decision that your residence is way too risky. When it comes down to it, why stress over surveillance systems and sensors when a burglar can pivot to a more vulnerable home somewhere else?
With that being said, the same studies note that signage ranks fairly low as a burglary deterrent. A wisely situated sign primarily puts off less experienced prowlers, but professional criminals might want to see the extent of security that is truly shielding your home prior to moving on. Other equipment, like security cameras, have greater success at preventing an intrusion.
