What is the primary purpose of a keypad in an alarm system?

The primary purpose of a keypad in an alarm system is to input codes for arming and disarming the system. This function is essential for the operation of security systems, as it allows authorized users to interact with the alarm system by entering specific codes that either activate or deactivate the alarm. The keypad serves as the main interface through which users can manage the security settings of the property, ensuring that only individuals with the correct authorization can control the system.

The keypad does not display security footage or power the system, as those functions are associated with different components, such as a display monitor or a power supply unit. Controlling the sensors is also outside the scope of the keypad's primary function, as sensor management typically occurs within the system's central control panel or through a dedicated configuration interface.
