What is the purpose of security surveillance systems?

The purpose of security surveillance systems primarily revolves around the ability to monitor and record activities for security purposes. These systems are designed to capture live footage and store it for later review, which can be crucial in identifying suspicious behavior, preventing incidents, and providing evidence during investigations. This ensures a safer environment by allowing security personnel to be aware of ongoing activities in real-time.

While other options do highlight aspects related to security—like deterring crime, managing employee performance, and controlling access—they do not fully encompass the primary function of surveillance systems. The primary role of these systems is rooted in monitoring and recording, which forms the basis of effective security management and response.
