HUCH Two-way Bike Alarm Kit  (Siren 1 dB)

A basic alarm kit typically includes a central control panel, sensors (like door/window contacts and motion detectors), and alerting devices (such as sirens or lights). The control panel acts as the brain of the system, receiving signals from sensors and triggering alerts. Sensors detect potential intrusions, while alerting devices notify occupants and potentially deter intruders. Modern systems can also include keypads for user interaction and smartphone apps for remote control and notifications.
