What is the primary function of surveillance cameras in security?

The primary function of surveillance cameras in security is to deter crime and provide evidence. When installed in various locations, these cameras serve as a visible reminder that activities are being monitored, which can discourage unlawful behavior. Potential criminals may think twice before committing an offense when they know that their actions are being recorded.

Furthermore, in the event that a crime does occur, the footage captured by surveillance cameras serves as crucial evidence that can be used in investigations and legal proceedings. This dual benefit of deterrence and evidence collection is essential in maintaining safety and order within a given area, whether it's a public place, private property, or a commercial establishment.

While other options mention aspects such as employee productivity or entertainment, these are secondary uses that don't align with the primary role of surveillance in a security context. Similarly, the idea of creating a false sense of security contradicts the authentic purpose of surveillance, which is to actively enhance security measures.
