What is the primary purpose of CCTV in security?

The primary purpose of CCTV in security is to monitor and record activities for security purposes. This technology is widely utilized to enhance safety by allowing security personnel or law enforcement to observe real-time incidents and gather evidence after events occur. By capturing footage of various locations, CCTV systems act as a deterrent against criminal activities, as potential wrongdoers are aware that their actions are being recorded. This recorded data is critical for investigations and can also serve as a reliable source of evidence in legal proceedings.

Other options, while they may seem relevant in different contexts, do not align with the primary function of CCTV. For instance, deterring customers from entering is not a suitable application of CCTV in security—it typically serves to encourage safe and secure environments rather than discouraging access. Providing live entertainment is unrelated to security; CCTV systems are not designed for entertainment purposes. Finally, while assessing employee productivity can theoretically be a byproduct of surveillance, it is not the main objective of CCTV systems in the context of security. Hence, monitoring and recording activities remains the defining role of CCTV in security systems.
