Abstract - Ensuring the safety of vulnerable groups such

as women, children, elderly individuals, tourists, and hikers has become increasingly critical in today’s rapidly evolving world. Safety concerns are exacerbated in environments where access to reliable communication networks is limited or unavailable. This paper presents Safe Connect, a versatile, wearable emergency alert device that integrates LoRa (Long-Range communication), GSM (Global System for Mobile Communication), and GPS (Global Positioning System) technologies to provide real-time emergency alerts and accurate location tracking [1]. Unlike conventional safety systems that rely solely on cellular networks, Safe Connect employs LoRa as the primary communication method for long-range alerts, making it highly suitable for rural or remote areas with poor cellular coverage. GSM acts as a backup, ensuring SMS alerts can be sent when LoRa is unavailable [2]. Additionally, the system features a camera module (ESP32-CAM) that captures real-time video footage and stores it locally on an SD card, which can later be retrieved as evidence. The system is designed to cater to a wide range of users, including women, tourists, children, elderly individuals, and hikers, offering a comprehensive and reliable solution that operates in both urban and rural environments. Testing demonstrates the device's ability to provide reliable alerts, real-time tracking, and robust performance in diverse conditions, making it an essential tool for enhancing personal safety across multiple demographic groups.

cellular networks, which may not be available in rural or remote environments. To address these limitations, the Safe Connect system offers a novel approach by combining multiple communication technologies: LoRa (Long Range), GSM, and GPS. This combination ensures that emergency alerts can be sent regardless of the user's location or network conditions. LoRa, which stands for Long Range, is a low-power wide-area network (LPWAN) technology designed to provide longrange communication while consuming minimal power. LoRa operates on unlicensed frequency bands, allowing it to transmit data over distances of up to 15 km in rural areas and 3-5 km in urban environments(main). This makes it an ideal solution for tourists and hikers in remote areas, where cellular networks may be unavailable. GPS (Global Positioning System) is another key component of the Safe Connect system. GPS is a satellite-based navigation technology that provides real-time location data with high accuracy It is widely used in various industries, from navigation and mapping to personal safety and emergency response systems. The integration of GPS allows Safe Connect to provide real-time location tracking, which is essential in helping emergency res- ponders locate individuals in distress quickly and accurately [3]. By integrating these technologies, Safe Connect not only provides a robust emergency alert system for urban environments but also ensures reliable communication in remote and under-served regions, making it a valuable tool for a wide range of applications, from personal safety in cities to outdoor activities such as hiking and camping.

INTRODUCTION

Personal safety is a significant concern in today's world, with rising instances of crime, accidents, and emergency situations affecting vulnerable groups such as women, children, the elderly, tourists, and hikers.[4],[5].These groups often face challenges in communicating distress in critical moments, especially when located in areas with poor or no network connectivity. While existing safety systems, like mobile applications and panic buttons, offer some solutions, they are typically dependent on reliable
