Which of the following enhances the functionality of surveillance systems in physical security?

The enhancement of surveillance systems is significantly bolstered by automated alerts. This functionality allows systems to proactively notify security personnel regarding unusual activities or breaches in real-time, enabling timely responses. By automating alerts, the surveillance system reduces the reliance on human operators to constantly monitor feeds, which can lead to fatigue or oversight. This feature optimizes the effectiveness of surveillance, as it streamlines the detection and response process.

In contrast, increased lighting may improve visibility but does not intrinsically enhance the functionality of the surveillance system itself. Higher production costs typically do not correlate directly with improved system functionality, as increased costs do not guarantee better performance or features. Reducing employee training can lead to a decrease in operational efficiency and effectiveness, as trained personnel are essential for interpreting surveillance data accurately and responding appropriately to threats. Therefore, automated alerts stand out as the primary method of enhancing a surveillance system's capabilities in the context of physical security.
