Which technology is commonly utilized by security guards?

Surveillance cameras and alarm systems are widely used in the security industry because they enhance monitoring capabilities and improve overall security management. Surveillance cameras allow security guards to observe and record activities in various areas, providing real-time visuals that can aid in crime prevention and incident response. Alarm systems can detect unauthorized access or emergencies, prompting immediate action to safeguard individuals and property. The integration of these technologies enables security personnel to effectively monitor large areas, respond swiftly to incidents, and gather evidence in the event of a security breach.

In contrast, options suggesting a focus on only personal radios or office computers fail to encompass the comprehensive technological tools that security guards rely on. Personal radios are primarily used for communication within a specific context, while office computers serve more administrative functions, lacking the immediate security enhancements provided by surveillance and alarm systems. Similarly, relying solely on phone applications does not represent the range of tools essential for effective security operations.
