What is "surveillance" in the context of security services?

Surveillance, in the context of security services, refers to the systematic monitoring of activities and behaviors with the primary goal of preventing crime. This practice involves observing individuals and environments to gather information that can help identify suspicious activities or potential threats before they escalate into criminal actions. By maintaining vigilance through various means, such as video footage, security personnel observations, and other monitoring methods, security services aim to create a safer environment for people and property.

This choice accurately encapsulates the essence of surveillance as a proactive security measure, focusing on crime prevention through constant observation and awareness. In contrast, while collecting evidence for legal cases, working with law enforcement, and conducting background checks are important functions within the security framework, they do not fully define the specific role of surveillance that is aimed directly at active monitoring for criminal behavior.
