What is the primary role of surveillance cameras in security?

The primary role of surveillance cameras in security is to monitor activities. Surveillance cameras are strategically placed in various locations to provide real-time visual monitoring of environments, helping security personnel observe behavior, detect unusual or suspicious activities, and ensure the safety of individuals and property. This function is essential in maintaining security, as it allows for immediate response to incidents, evidence collection in case of disputes or criminal activities, and deterrence against potential wrongdoers who are aware they are being recorded.

The other choices do not align closely with the primary purpose of surveillance cameras. While reducing operational costs may be a secondary benefit due to improved security efficiency, it is not the main role. Providing internet connectivity is unrelated to the purpose of surveillance cameras, which focus on monitoring rather than connectivity. Limiting employee access may involve other security measures, such as access control systems, rather than the primary function of a surveillance camera. Thus, monitoring activities stands as the core function of surveillance cameras in security contexts.
