SMS Based Alert System for Shoplifting

—Shoplifting has long been a problem for the retail industry and there can also be store-related problems due to financial losses. Traditional forms of security, like closed-circuit television cameras and human security personnel, do not necessarily guarantee instantaneous alerts and are continuously monitored. In view of the above, the current project aims to develop a simple and inexpensive SMS alert system capable of detecting suspicious activities movement in the shop and immediately notify the proprietor. The project is made by utilizing the following components: Arduino UNO, microwave motion sensor, GSM module, relay module, buzzer, LED indicators, and wireless transmitter/receiver modules. When the unusual activity is detected, the system activates the local alarms and sends an SMS to the shop owner. The proposed system is easily installable, economical, and appropriate for small and medium-scale retail business operations. III. PROBLEM STATEMENT Retail stores suffer losses due to unauthorized movement and unnoticed shoplifting activities. Ongoing monitoring systems lack instant alert capability or require constant human oversight. There is a need for a low-cost, automated security system capable of detecting suspicious activity and notifying the shop owner immediately through SMS.
