What does the term "surveillance" refer to in the security field?

The term "surveillance" in the security field primarily refers to the monitoring of behavior and activities to implement preventive measures. This involves observing people, places, or situations to identify potential threats or unauthorized actions before they escalate into more serious incidents. Surveillance can be done through various methods, including physical observation, the use of cameras and other technology, and analyzing data patterns. This proactive approach is essential in maintaining safety and security within any environment.

The focus on prevention is critical because effective surveillance can deter criminal behavior, gather essential information for investigations, and enhance overall safety protocols. The continuous monitoring allows security personnel to respond quickly to suspicious activities, thereby potentially preventing incidents before they occur.
