A smart home sensorized security system consists of several electronic devices like Camera, sensor and a wireless communication device which provide owners to remotely access the security system and also on wireless devices they get the SMS notification. There are many camera devices that may constantly keep eye on the sites. The camera devices consist of PIR sensors that are used for motion detecting functions and provide unusual status reporting signals and necessary image information to the communications device when the movements of an unknown person have been observed. The wireless communication or SMS communication is done via GSM module. For giving alert information SMS communication is used for security purposes. If an unknown person attempts to enter the house, an alarm is sent to the cell phone to which the device is attached, informing the person regarding presence of someone inside the house while the owner not at home. The house owner can then take whatever action he likes, such as calling the cops or his family, to protect his home from an unknown intruder. When the device is in active mode, it will also start alarming if an unknown person enters the building. [ABSTRACT FROM AUTHOR]
