What are surveillance cameras primarily used for in security?

Surveillance cameras are primarily utilized in security to serve as a deterrent to crime and to provide evidence in case an incident occurs. When visible, these cameras can discourage potential criminal activity because individuals are aware they are being monitored. This deterrent effect can contribute to a safer environment in various settings, such as retail spaces, public areas, and private properties.

In addition to acting as a deterrent, surveillance footage can be crucial in investigations following an incident. The video evidence collected can help identify suspects, clarify the sequence of events, and substantiate claims during legal proceedings. This dual purpose of deterring crime and providing valuable evidence underlines the importance of surveillance cameras within the realm of security.

Other choices, while relevant in different contexts, do not capture the primary function of surveillance cameras within security. Monitoring employee productivity, ensuring equipment functionality, and tracking inventory movement are important aspects of operational management but are not the main objectives of security surveillance systems.
