        an event receiving information storage unit 520 for storing information of the security company terminal 600 and the mobile terminal 650 of receiving the event detection signal therein;
        a unique ID information storage unit 530 for storing a unique ID number of a building having the detection sensor, a unique ID number by installation location, and a detection threshold information therein;
        an event generation determination unit 540 for comparing the detection threshold information with the received detection signal so as to determine as to whether the event is generated or not;
        an event signal generation unit 550 for generating the event detection signal when it exceeds the threshold information in the event generation determination unit 540; and
        an event signal transmission unit 560 for transmitting the event detection signal to the security company terminal 600 and the mobile terminal 650 stored by the event receiving information storage unit 520 through a message.
    
    


The detection signal acquiring unit 510 serves to acquire the detection signal information transmitted from the RF dongle installed in the Internet sharer 400.
The event receiving information storage unit 520 serves to store the information of the security company terminal 600 and the mobile terminal 650 of receiving the event detection signal therein.
That is, the information such as the unique number of the security company terminal 600 and the mobile terminal 650 for receiving the corresponding generation information during the generation of the event is stored therein.
The unique ID information storage unit 530 serves to store the unique ID number of the building, in which the detection sensor is installed and configured, the unique ID number by installation location, and the detection threshold information therein.
In other words, the unique ID numbers of the building are given to each building and the unique ID numbers by installation location are given to the bedroom window and the living room window having the detection sensors and so on, so that the given numbers are stored therein.
The detection threshold information means the reference point for generating the event when it exceeds the predetermined threshold value.
The event generation determination unit 540 serves to compare the detection threshold information with the received detection signal so as to determine as to whether the event is generated or not. For example, if the detection sensor is a vibration sensor, when the vibration value of the vibration detection signal is 50 and the threshold value is 100, it is judged as a vibration due to normal wind conditions. On the contrary, the vibration value of the vibration detection signal is 150, it is judged as the generation of the event.
The event signal generation unit 550 serves to generate the event detection signal when it exceeds the threshold information in the event generation determination unit 540.
In other words, the generated unique ID number of the corresponding building, the generated unique ID number of the corresponding installation location, and the detection value and so on are acquired to be added to the event detection signal.
The event signal transmission unit 560 serves to transmit the event detection signal to the security company terminal 600 and the mobile terminal 650 stored by the event receiving information storage unit 520 through the message.
In other words, the event signal transmission unit 560 transmits the event detection signal to the mobile phone No. 010-123-4567 as the event message.
