The main function of surveillance in security operations is to collect evidence and monitor activities. This involves closely observing individuals and situations to ensure safety, security, and adherence to policies and regulations. By effectively monitoring activities, security personnel can detect unusual behavior, prevent potential incidents, and respond promptly to any threats or emergencies. Surveillance systems, whether they involve physical monitoring by guards or the use of cameras, provide valuable insights and data that can be crucial in investigations or legal proceedings. This proactive approach not only aids in maintaining security but also helps in fostering a sense of safety within the area being monitored.

In contrast, the other options do not align with the core purpose of surveillance in security. Entertaining guests does not contribute to security operations, and while deterrence is a secondary benefit of surveillance, it is not the primary function. Conducting exit interviews is a human resources activity, unrelated to monitoring or ensuring safety within a security context.
