Which is a type of security equipment?

• A. Perimeter alert systems
• B. Surveillance cameras
• C. Microwave motion detectors
• D. All of the above

Answer: (D)

Security equipment includes devices that detect, monitor, or alert us to potential threats, forming a layered approach to protection. Perimeter alert systems focus on the boundary lines and trigger alarms when someone tries to breach a restricted area, helping stop intrusions at the point of entry. Surveillance cameras provide ongoing visual monitoring and recording, which supports immediate responses and later investigations. Microwave motion detectors sense movement over a wide area using microwave signals, often functioning independently of lighting conditions to alert security personnel to motion in a space. Because each type serves a different role in protecting people and property, all of them are valid examples of security equipment, so recognizing that all three are used together reflects a comprehensive security setup.
