Question

question 10 (1 point)
a limited - use alarm system set to accept a predetermined radiation level and trigger an alarm if a person enters the area.
infrared radiation detection
local alarms
microwave detectors
question 11 (1 point)
security technology which utilizes an individuals unique characteristics, including fingerprint, eye, and voice recognition.
infrared radiation detection
biometrics
closed - circuit television
question 12 (1 point)
controlling access to neighborhoods and buildings and conducting surveillance on specific areas to reduce opportunities for crime to occur.

Explanation:

For Question 10, infrared radiation detection can detect changes in infrared radiation when a person enters an area. Local alarms are just a type of alarm and not related to radiation - based triggering. Microwave detectors work on microwave signals, not radiation levels for the context described. For Question 11, biometrics uses unique physical or behavioral characteristics like fingerprint, eye, and voice for security. Infrared radiation detection is about detecting heat - related radiation, not unique personal characteristics. Closed - circuit television is for visual surveillance, not for using personal characteristics for security.

Answer:

Question 10: Infrared radiation detection
Question 11: Biometrics
Question 12: No options provided to answer.
