What is the primary function of surveillance cameras?

1. To provide live entertainment for viewers

2. To identify all individuals entering a facility

3. To monitor activities and record evidence for security purposes

4. To control access to restricted areas

The correct answer is: To monitor activities and record evidence for security purposes

The primary function of surveillance cameras is to monitor activities and record evidence for security purposes. This encompasses a wide range of tasks, including observing and documenting events as they happen to deter potential criminal activity, assist in investigations, and provide video footage that can be utilized as evidence if an incident occurs. Surveillance cameras serve as a crucial tool for security personnel by allowing them to keep an eye on different areas, ensuring safety, and maintaining a secure environment. They provide visual documentation which can be reviewed later in cases of incidents, helping to establish what occurred during security breaches or other events that may require investigation. In contrast, focusing on identifying all individuals entering a facility does not fully capture the comprehensive role of surveillance cameras, as their function is broader than merely identification. Similarly, while they can aid in monitoring restricted areas, they do not inherently control access to these areas, which typically involves other security measures such as keycards or security personnel. Lastly, the notion of providing live entertainment lacks relevance to the serious security aims of surveillance cameras, which are specifically designed for safety and preventative measures.
