What role do sensors play in alarm systems?

Sensors are a critical component of alarm systems because they are responsible for detecting specific conditions or activities, such as movement, sound, or environmental changes. When a sensor detects an event that fits its programmed parameters—like motion in a restricted area or a change in temperature—it triggers the alarm system to respond accordingly. This could involve sounding an alarm, notifying a monitoring service, or sending alerts to the property owner.

The primary function of sensors is to provide real-time monitoring and prompt action in the event of an intrusion or emergency situation. Therefore, their role in triggering alarms and alerts based on these detected conditions is essential for the effectiveness and reliability of any security system. Other options may touch on different aspects of alarm systems, but they do not encapsulate the core function of sensors in the same way.
