We implemented an advanced security system to the bank vault to keep protect from an unauthorized person or theft. The aim of this project is to design an advanced security system for Bank Vault utilizing GSM technology, which provides a secure, genuine, user-friendly mechanism for the safety of the Vaults. The current security systems in the bank use the mechanical key for security purpose. Comparatively, with today's digital world, this system provides slow service. To improve this state, we proposed a GSM-based advanced security system with seven sensors like Gas Sensor, Ultrasonic Sensor, Laser Sensor, Vibrator Sensor, Sound sensor, Motion Sensor, and Light sensor for the bank vaults of Bangladesh. The seven sensors can detect any symptoms of theft. At the same time, the SMS alert will be work to send a message to the authorized number. The GSM security has been proven to be far more superior stronger and safer than the traditional system.
