What is the primary tool for maintaining security in a facility?

Surveillance equipment is vital for maintaining security in a facility because it allows for continuous monitoring of the premises. This includes the use of cameras, alarms, and sensors, which help to detect unauthorized access, monitor activities, and deter potential criminal behavior. By providing real-time visuals and alerts, surveillance systems can enhance response times and improve overall situational awareness for security personnel.

In contrast, while legal resources can assist in navigating issues related to security protocols and compliance, they do not serve as a direct tool for maintaining facility security. Physical strength, although important in some security situations, is not sufficient on its own without the aid of technology and monitoring systems. Customer complaints may indicate security issues but are reactive rather than proactive measures. Therefore, the use of surveillance equipment stands out as the primary method for actively preserving security within a facility.
