Question

question 4 (1 point) a perimeter control system with long - range capabilities and tamper - proof characteristics that detects motion by transmitting and receiving electromagnetic energy. biometrics local alarms microwave detectors question 5 (1 point) a cctv system is only as effective as the monitoring system and the propertys ability to respond reasonably to what may be observed. false true question 6 (1 point) class ______ fires involve ordinary combustibles. a c b

Explanation:

• Question 4: Microwave detectors use electromagnetic energy (microwaves) to detect motion, which matches the description. Biometrics is related to identifying individuals based on physical or behavioral traits, and local alarms are just for alerting, not detecting motion via electromagnetic energy.
• Question 5: The effectiveness of a CCTV system indeed depends on the monitoring system and the ability to respond to what is observed. If there is no proper response mechanism, the CCTV system's value is limited.
• Question 6: Class A fires involve ordinary combustibles such as wood, paper, and cloth. Class B fires involve flammable liquids and Class C fires involve energized electrical equipment.

Answer:

Question 4: C. Microwave detectors
Question 5: B. True
Question 6: A. A
