Once the abnormal situation is found, theintelligent home security alarm system will start the acousto-optic alarmprompted by the LED lamp and pass through the information processingsystem of the GSM module. Send an abnormal text message to the user ofthe security system at the first time face, and finally realize the purpose ofmodern intelligent home security alarm.展开更多
