The primary role of surveillance in security operations is to monitor activities and deter criminal behavior. Surveillance serves as a proactive measure that helps to observe and analyze behaviors within a designated area, allowing security personnel to identify suspicious activities in real-time. This observance can lead to timely interventions, preventing crime before it occurs or escalating.

Surveillance not only aids in the immediate detection of potential threats but also acts as a deterrent; the mere presence of surveillance cameras or security personnel can discourage criminal activity by increasing the perceived likelihood of being caught. This dual function enhances overall security effectiveness by maintaining a safe environment.

While documentation through video footage, managing access control, and conducting interviews are important aspects of security operations, they are secondary functions compared to the fundamental objective of surveillance, which is centered around monitoring and deterring unlawful behavior.
