Abstract
This project is designed to improve the home safety and the conventional alarm system today. The project is not only a normal intercom but also detect any trying to enter the home by enter wrong ID and password and turn on the bell alarm, also tell the owner by calling his hand phone. The main focus of this project is to make an overall security system by access the home by many ways which include mobile password by generate the DTMF (Dual Tone Multi Frequency) tones using a cheap PIC Microcontroller and the corresponding circuit. The theory of the DTMF tones generation is discussed in quite detail with suitable graphs shown in this report, also by using keypad which you can save many IDs and passwords reach maximum 15 ones . This project is already done successfully since we saved three different password for mobiles and 15 by keypad, and able to make a call to a specific hand phone number and access the door.
