Development of camera and GSM interfacing system for home security surveillance

This project is developed with aims to improve home security systems available in current market. This project claims to produce a prototype camera and global system for mobile communication (GSM) interfacing system for home security surveillance. This system uses two sensors, namely ultrasonic and passive infrared receiver (PIR). The ultrasonic sensor is used to detect movement of objects and PIR function is to detect changes in temperature of human in infrared radiation. In this project, the microcontroller used is ATMega 32, where it sends data to the computer to activate the camera when the microcontroller receives signals from PIR and ultrasonic. MAX232 is used as an interface circuit connecting the microcontroller to the computer. To develop software for the control circuits, software CodeVision AVR is used because the software supports microcontroller ATMega of 32. Once the camera is activated, it will capture images of intruder and the image will be saved and sent to the mobile phone. Then the sending process will automatically operate. For the transmission of picture (MMS), the software used is ActiveXperts because they support the process of sending picture from computer to phone via GSM/GPRS modem. In carrying out this project, the mobile phone Nokia 6000 series is used as a GSM/GPRS modem. In conclusion, this system operates by detecting the entry of an intruder to home by capturing the image and data (image) which will be automatically sent to the mobile phone.
