What is the function of surveillance systems in security?

Surveillance systems play a crucial role in security by monitoring activities and providing evidence of incidents. They serve as a proactive measure to help detect and deter unlawful behavior or actions that could compromise safety and security. By capturing footage or data in a specific area, these systems enable security personnel to review incidents, leading to informed responses and investigations if necessary.

The visibility that surveillance creates can deter potential offenders who may reconsider engaging in illicit activities when they know they are being monitored. Additionally, in the event of an incident, recorded footage can serve as critical evidence for investigations, legal proceedings, or for assessing the effectiveness of security protocols. This capability enhances overall safety and provides accountability within an environment, making it an essential function of security systems.

The other choices do not accurately reflect the primary role of surveillance in security, as they pertain more to operational management or administrative tasks rather than security monitoring and incident management.
