Yes, home security signs are able to deter intrusions in Lima
Numerous studies indicate that security signs work when attempting to deter an intrusion. The idea is that the burglar will see the display and instantly determine that your residence isn't worth the hassle. Ultimately, why worry about security cameras and sensors when a burglar can move onto an unprotected home somewhere else?
With that being said, the same research indicates that a visible display isn’t the strongest deterrent to crime. A well-placed sign mainly dissuades amateur thieves, but seasoned thieves might want to see how much security is truly defending your property before deciding on a different target. Other components, like security cameras, are more effective at thwarting prospective invaders.
