The primary purpose of security signage is to inform and deter potential violators. Effective security signage communicates important information to anyone entering or passing by a property. This signage typically includes warnings about surveillance, restricted areas, and consequences for trespassing, which serve to both inform individuals of the presence of security measures and act as a deterrent to potential unlawful activity. By clearly stating the rules and consequences, security signs help in establishing a secure environment and reinforcing the property owner's intent to protect their assets.

While other options may play a role in how signage is utilized, they do not capture the essential function of security signage as effectively as informing and deterring do. Decoration, directions, or advertising can certainly be components of signage, but they are secondary to the critical objective of maintaining safety and security.
