The goal of the current study was to design an Internet of Things-based mobile application for the purpose of constructing closed citizen security circuits in small communities. A Canvas model, which offered a comprehensive understanding of the commercial strategy to be followed and provided essential information for decision-making, and a SWOT analysis, which also looked at the advantages, disadvantages, opportunities, and threats of the environment in which the prototype was made, were used to first identify the security needs of the community. An SCRUM-based applied approach that encouraged project agility was put forth. Google used Firebase to plan the database and React Native, a programming language, to construct the application, which enabled the creation of an iOS and Android app. The application’s graphical user interface was simple to use and straightforward. The platform’s design suggested creating roles, such as a security agent who can see requests and a regular citizen who, when an assistance request is generated, turns on geolocation to show their position on a real-time map. A map derived from the Google Maps API was utilized for this. Furthermore, a landing page was suggested to advertise community security-related events and content, such as preventative culture and best practices for reporting. This website included an online platform for assigning security agent responsibilities and managing registered users. The platform also has a chat function that enables real-time communication between all users in a closed circuit, including direct messages and messages in a worldwide channel. In summary, the development’s first findings demonstrated a strong dedication to enabling local communities to improve citizen security with the use of 4.0 technologies. This strategy improves the relationship between the state and the community while streamlining communication between community players.
