How does access control integration assist in surveillance monitoring?

The correct answer highlights the value of integrating access control systems with surveillance monitoring. By allowing the viewing of security access events alongside video footage, this integration becomes a powerful tool for enhancing security measures. It enables operators to correlate specific access control events, such as door entries or exits, with recorded video from nearby cameras. This correlation aids in investigations by providing context to who accessed certain areas and at what time, ultimately improving response times and situational awareness.

The other options, while they relate to various aspects of security and surveillance systems, do not capture the core benefit of access control integration. Utilizing multiple software applications can make the system more complex and may not directly enhance surveillance monitoring. Restricting camera feeds to authorized personnel is more about managing access rights rather than integrating data for effective monitoring. Lastly, while improving storage capacity is an important aspect of any video surveillance system, it does not relate to the functionality of access control integration in monitoring activities. Thus, option B clearly illustrates a critical advantage of this integration, making it the best choice.
