The main objective of this project is to intimate the
concerned authorities about an unauthorized access of secured areas such
as museums, residential houses, banks etc. As crime rate is on the rise
and burglars are getting smarter, the security system for banks, shops
and houses needs to be full proof. This proposed system ensures that at
any moment if any unauthorized person tries to open the bank locker; a
telephone number will be dialed through the telephone line connected to
it.
This project uses a microcontroller from 8051 family. An external memory EEPROM is interfaced to the microcontroller to store the contact number to which the call is to be made. The arrangement is made in such a way that when someone tries to open the door forcefully even when it is locked the microcontroller gets an interrupt through a hidden switch mechanism interfaced to it. Microcontroller will automatically dial to the number which is stored in the EEPROM through DTMF encoder interfaced to it. Microcontroller fetches information from external memory like EEPROM using I2C (Inter IC communication) protocol.
Further this project can be enhanced to use a cell phone or GSM modem with a serial camera connected to it. The camera will take photographs and sends it over MMS/ email attachment to the concerned authorities.
