SecureShield: A Smart Security System

Abstract

Introduction: Mainstream bank security measures are largely based on manual guarding and ordinary electronic locks, which makes banks vulnerable to the threat of illegal entry and slow response to attacks along with inabilities to monitor. Whereas the demand for the real-time alerts, intelligent control and immediate emergency action further increases, existing security systems are not sufficient and highlight the need for total, automated security systems.

Objectives: The main focus of the project was the development and integration of a high-megatrend, IoT-based security system – SecureShield – specializing in protecting bank lockers. The system was designed to provide real time monitoring, prevent unauthorized access, and facilitate rapid emergency intervention, through advanced sensing and communication technologies.

Methods: A principal part of the system was also an ESP32-CAM module, that conducted real-time image analysis when someone attempted access to the locker, and sent images to a telegram bot to ensure remote monitoring and confirmation. In the interest of detecting the unauthorized access, we did use a laser intruder detection system connected to an Arduino Uno which alerts only if it detects repeated beam interruptions in order to avoid false positives for confirmed access. Additional precautions were integrated with a PIR sensor to light the locker area when motion is effected and flame sensor used to send alarms upon fire detection. A solenoid lock acted as the main accessibility control system, flawlessly integrated into the rest of the system’s processes.

Results: The experiments demonstrated that the SecureShield system enhanced security through real-time visual tracking, advanced intrusion tracking, and on-the-spot emergency measures. The laser mechanism reliably distinguished between valid access and attempted baboon attempts, and the use of ESP32-CAM and Telegram guaranteed prompt remote verification. The system was flexible in locker aspects and it worked dependably in real time operations.

Conclusions: Using a multi-layered IoT framework, the SecureShield system effectively reduces major security threats when treated in bank locker facilities. The project combines vision based monitoring, laser intrusion detection, environmental sensors, and real time communication to provide a solid and sophisticated security solution for a financial institution that is securing its assets. The development promises good prospects for adoption in a very diverse set of high security environments
