What is one function of a peripheral device in a security system?

A peripheral device in a security system serves several important functions, and the function of sending notifications is a key role. Peripheral devices can include components like alarms, sensors, or notification panels that alert users to potential security breaches or system statuses. When a security event occurs, these devices are crucial in providing immediate feedback and alerts to the relevant parties, thereby enhancing the overall responsiveness and effectiveness of a security system.

The ability to send notifications is essential for timely awareness and action; for example, a motion detector that triggers an alarm or sends a text alert to the homeowner is performing a critical function in a security system. This ensures that users are informed about real-time events and can respond appropriately.

Other options, while relevant functions in different contexts, do not specifically align with the primary role of peripheral devices in the security system's immediate operation. For instance, processing information is typically handled by the central control unit rather than peripheral devices. Similarly, transmitting data to a server is more commonly associated with communication devices or networked systems, and controlling the power supply would involve power management equipment rather than the peripheral devices focused on user notifications and alerts.
