Yes, home security signs are able to deter intrusions in Bakersfield
Many studies indicate that security signs work when looking at ways to deter an intrusion. The reasoning is that the burglar will see the display and quickly determine that your residence isn't worth the hassle. When it comes down to it, why get concerned about security cameras and motion detectors when a thief can hit a more vulnerable mark in another neighborhood?
However, the same studies note that a security sign ranks fairly low as a burglary deterrent. A well-placed sign mainly puts off amateur thieves, but professional criminals may want to see the level of security that is actually shielding your home prior to looking the other way. Other devices, like outdoor video cameras, do a much better job keeping an intruder away.
