Monitoring Home By Cellular Technology

Abstract

Mobile phone can serve as powerful tool for world-wide communication. A system will be developed to remotely monitor process through sending messages using mobile. This system is based on GSM network technology for transmission of messages (Multimedia Messaging Service MMS, Short Message Service SMS) between system and owner. The system maintains the security alert which is achieved in a way that on the detection of any abnormal events, the system allows automatic generation of messages thus alerting the user against security risk. Sensors will detect any abnormal events happens inside the home, such that gas leaking, fire, and outer threats, send signal to microcontroller , after that PIC make some processing of received signal, then transmit to it to PC where makes some local analysis in order to turn event's room cameras on . The camera will captures a stream of images and videos ,transmit to PC. PC then store captured images and videos in a file for later owner usage, PC then send an image to peer mobile in addition to useful information about system state. Peer mobile sends MMS message containing event image, plus a text message containing house state information, then send to Terminal Mobile carried by owner. This Message will tell the owner what happened in his home by using specific control word written in the text part also it's provide the owner an image which express to him event nature occur inside his home.
