Figure 1 shows the components that contribute to the system's functionality and compact design.
At its core is the ESP32-CAM module, which serves as the primary processing unit, integrating a camera and Wi-Fi capabilities. This module is ideal for this application due to its small size, low power consumption, and ability to stream video, allowing users to capture critical moments during emergencies. The camera lens is positioned strategically at the top, enabling unobstructed video recording while maintaining a low profile.


Powering the device is a compact 3.7V LiPo battery, chosen for its lightweight and rechargeable nature. This battery provides the necessary energy to keep the device operational during critical situations. Its small size ensures that it fits seamlessly within the 3D-printed case without adding unnecessary bulk. The TTP223B capacitive touch switch allows users to activate the device discreetly with a simple triple tap, providing an intuitive user interface that is both effective and unobtrusive. This touch switch is particularly suitable as it minimizes the risk of accidental activation while ensuring quick access in emergencies.
To facilitate communication, the FT23RL USB module is incorporated into the design for easy recharging, ensuring that the device remains powered and ready for use. The MAX9814 microphone complements the system by capturing audio alongside the video, which is crucial for documenting incidents and enhancing situational awareness. Its adjustable gain feature allows it to capture sound clearly even in noisy environments, making it a valuable addition for emergency situations.
Additionally, the antenna with an IPEX connector is essential for transmitting distress signals effectively. This component ensures that the device can communicate even in areas with weak network signals, thereby increasing its reliability in emergencies.

Figure 2 - WORKFLOW DIAGRAM
The workflow of the wearable safety device is designed to ensure swift and discreet emergency response. It begins when the device is powered on or in standby mode, ready for activation.
Users can trigger the emergency mode by performing a simple triple tap on the TTP223B capacitive touch switch, which initiates the system's alert process.
Upon activation, the ESP32-CAM module receives the signal from the touch switch and begins recording audio and video, capturing critical details of the environment. The device simultaneously provides feedback to the user through a vibration motor, confirming that the

emergency mode is active. This feedback is crucial as it reassures the user that help is being sought without drawing unwanted attention.
Next, the device checks for communication availability. If a Wi-Fi or radio frequency (RF) signal is accessible, the ESP32-CAM module sends a distress signal, along with the recorded data, to the designated emergency contacts. If no network is available, the device can store the emergency data locally on the SD card until a connection is restored, ensuring that vital information is not lost.
The recorded audio and video are encrypted to protect the user's privacy and prevent unauthorized access. Once the distress signal is sent successfully, the device continues to operate, recording and transmitting data until the user deactivates it or the battery runs out. This streamlined workflow prioritizes user safety, ensuring that help can be summoned discreetly and efficiently in critical situations, while also safeguarding the recorded information for future reference.
