Yes, home security signs are able to deter intrusions in Des Moines
Various studies confirm that security signs work when attempting to deter an intrusion. The reasoning is that the thief will see the signage and swiftly determine that your property is way too risky. Ultimately, why worry about surveillance systems and sensors when a burglar can hit a less protected mark in another neighborhood?
Nevertheless, the same studies note that a security sign ranks fairly low as a burglary deterrent. A smartly positioned sign primarily discourages amateur thieves, but veteran crooks might want to see the level of security that is really protecting your property prior to moving on. Other equipment, like outdoor video cameras, are more effective at keeping an intruder away.
