Yes, home security signs will deter intrusions in St. Paul
Many studies confirm that security signs are effective when considering how to deter an intrusion. The idea is that the burglar will notice the display and quickly make the decision that your residence is a poor choice to target. When it comes down to it, why worry about cameras and motion detectors when they can move onto an unprotected mark somewhere else?
With that being said, the same reports show that a security sign ranks fairly low as a burglary deterrent. A well-placed sign mainly dissuades amateur thieves, but professional thieves will want to discover how much security is really protecting your house prior to looking the other way. Other components, like cameras, do a much better job preventing an intrusion.
