 The system begins with the Nicla Voice, which runs a trained machine learning model to detect glass-breaking sounds. For this, we will use the model as discussed in the [Machine Learning Model Development](#machine-learning-model-development) section. Upon recognizing such an event, the Nicla Voice sends a notification via Bluetooth® Low Energy (BLE) to the Portenta H7.

 The Portenta H7 is the host device, bridging the detection hardware with the Arduino Cloud. It receives the BLE notification, processes the alert, and updates the cloud dashboard in real-time. Additionally, the Portenta H7 triggers specific actions based on the alert level:
 
 - **Security Alert Call:** It is activated upon recognizing the first glass-breaking event. This is to provide an immediate warning that a critical event may have occurred, enabling early intervention.
