Which technology can assist security guards in their duties?

Advanced surveillance systems are an essential technology that can significantly enhance a security guard's ability to perform their duties effectively. These systems include high-definition cameras, motion sensors, and video analytics, which allow security personnel to monitor premises in real time and record evidence of any incidents. The use of advanced surveillance systems can improve situational awareness, assist in identifying suspicious behavior, and provide valuable footage for investigations following an event.

In contrast, while personal mobile devices can provide communication and some monitoring capabilities, they do not offer the comprehensive surveillance features that dedicated systems do. Social media platforms and entertainment systems do not provide relevant support for security duties; they are primarily used for communication or leisure rather than for safety and security purposes. Therefore, advanced surveillance systems are the most effective technology to aid security guards in their roles.
