Question

a perimeter control system with long - range capabilities and tamper - proof characteristics that detects motion by transmitting and receiving electromagnetic energy.
biometrics
microwave detectors
local alarms
question 26 (1 point)
alarm systems designed to prevent and/or detect intrusion on a hotel or motels property or grounds.
closed - circuit television
contact alarms
perimeter control
question 27 (1 point)
a perimeter control system in which a filtered light beam passes between a sending and receiving unit; any break in the beam sets off the alarm.
perimeter control
photoelectric light beam
microwave detectors

Explanation:

1. For the first question, microwave detectors detect motion by transmitting and receiving electromagnetic energy, which matches the description. Biometrics is related to human - biological characteristics for identification and local alarms are a general category not specific to this electromagnetic - based motion detection.
2. For the second question, contact alarms are designed to prevent and detect intrusion on property by sensing contact - related changes, like a door or window being opened. Closed - circuit television is mainly for monitoring and perimeter control is a broader category.
3. For the third question, a photoelectric light beam system has a filtered light beam between a sending and receiving unit, and a break in the beam sets off the alarm, which is exactly what is described. Perimeter control is too general and microwave detectors work on a different principle.

Answer:

1. B. Microwave detectors
2. B. Contact Alarms
3. B. Photoelectric light beam
