Yes, home security signs are able to deter intrusions in Champaign
Many studies say security signs are effective when looking at ways to deter an intrusion. The idea is that the prowler will discover the display and instantly decide that your property is a poor choice to target. When it comes down to it, why get concerned about cameras and motion detectors when a thief can hit an unprotected home down the road?
However, the same research indicates that a visible display isn’t the strongest burglary deterrent. A well-placed sign mainly puts off less experienced prowlers, but professional thieves will want to find how much security is actually shielding your house before looking the other way. Other components, like security cameras, do a much better job preventing an intrusion.
