Abstract

Nowadays, the number of banks and the number of theft is increases\nrapidly. Most of the customers are using bank operations for savings account,\nkeeping valuable jewels in the bank locker and availing loan for purchase of\nhome. Most of the time, theft happens in the bank which results in major losses to\nbank owners and customers are also affected. The conventional bank security\nsystem is not effective and theft of money, jewels etc. happen easily. The police\ncannot find the robbers easily. The proposed bank security system is novel,\nhighly secure and cost effective embedded system which ensures bank security\nby releasing knock-out gas. It is used only after the closing hours of banks. When\nany robber tries to enter the bank, the sensor kept near the locker senses and\nsends the signal to microcontroller. The microcontroller which inturn sends the\nsignal to the relay circuit which activates the gas releasing equipment to release\nthe knock-out gas for specified period of time. The signal from the\nmicrocontroller also sends to the Bank’s higher officials mobile through the GSM\n(Global System for Mobile Communications). The novelty of this proposed\nsecurity system is it releases knock-out gas towards robber which makes him\nunconscious and falls down for certain hours. This system allows bank manager and police to easily catch the robber. The proposed bank security system is fully\nautomated bank security system which ensures safety to highly valuable\ncustomer’s documents, money and expensive ornaments kept in bank locker.
