Design and Implementation of a Community-Based Neighborhood Alarm System Using a PC-Hosted Telegram Bot

Abstrak

Neighborhood security is still a major worry, especially in residential areas with high population densities where quick action is necessary to control emergencies and deter crime. Current security systems frequently depend on IoT devices dispersed throughout several locations or manual monitoring, which can raise costs and complexity. This study suggests creating and deploying a neighborhood alarm system that is controlled by a Telegram bot hosted on a PC. Through the system, sirens linked to an amplifier-speaker/TOA network placed in key locations throughout the neighborhood can be turned on and off by registered users. User authentication, access control, alarm activation, and Telegram-delivered real-time status updates are some of the main features. By using a centralized PC as the control center, the architecture eliminates the need for numerous IoT devices and streamlines maintenance. Based on experimental results, the system is a viable solution for enhancing community security and cooperative response in emergency situations because it achieves a fast response time, dependable operation under network conditions, and high user acceptance.
