How do intrusion detectors work?
What will be an ideal response?
Intrusion detectors trigger an alarm when someone enters an unauthorized area. When an alarm is triggered, it sounds an auditory alarm, activates lights, and transmits information to the central control system where an operator can alert security staff. The most common detectors use magnetic devices mounted on doors and windows that transmit a signal when opened.
