The correct answer highlights key technologies that are essential in enhancing security measures for facilities. Alarm systems serve as the first line of defense, alerting security personnel and law enforcement to potential breaches or emergencies. Access control systems manage who can enter specific areas within a facility, ensuring that only authorized personnel have access to sensitive or restricted zones. Video surveillance acts as both a deterrent to criminal activity and a means of gathering evidence, allowing for real-time monitoring and recorded documentation of incidents as they unfold.

These three technologies work in concert to provide a comprehensive security framework. Alarm systems can trigger immediate responses, access control can prevent intrusions, and video surveillance captures events for later review, thereby allowing security teams to respond effectively to incidents. In contrast, while the other choices include useful tools, they do not focus as directly on the core technologies that enhance security in a facility.
