Referring to the operation of the preferred embodiment according to the present invention configured as described above in more detail with reference to Figures 1 to 3 as follows.

First, in a state in which the computer 100 and the detection sensors 410 to 440 operate normally (S101), when an intruder is generated in a house and a door such as a front door or a window is opened and closed, the door detection sensor 410 or a motion detection sensor ( The 430 detects this, and the monitoring controller 200 notifies the main controller 120 of the detection result of the door detection sensor 410 or the motion detection sensor 430. Likewise, in other situations such as fire and gas leakage, the main controller 120 notifies the detection result of each of the detection sensors 420 and 440 (S102, S104, S106, and S108).

Then, the main control unit 120 is a pre-stored alarm sound or warning message in the data storage unit 140 (for example, 'beep ~ ~ ~ now you have trespassed into our master's house. From now on all your actions Is monitored on the computer, video recording is in progress and all the details have been sent to the security company ') to output this situation through the speaker 210 to notify the surroundings. On the other hand, in a situation such as a gas leak, it is preferable to add a function of forcibly shutting off the gas valve (not shown) by providing a separate operation means (S103, S105, S107, S109).

At the same time, the main control unit 120 operates the image input unit 220 and the audio input unit 230 to receive the image and audio data of the current situation and store it in the data storage unit 140 (S110).

Subsequently, the main control unit 120 operates the fax / modem 130 to perform a phone call or fax transmission to a predetermined place (for example, a nearby police station, a security service company, a home owner's mobile phone or an office, etc.). do. At this time, when the phone call and fax transmission to the designated place, the contents and occurrence time of the current situation (theft invasion, fire, gas leak, etc.), and in the case of the fax (330), the location, the map, and the field photo (the image input by the camera) And the like, and at the same time, transmit an Internet connection request according to a situation such as unauthorized intrusion or fire (S111 to S112).

In addition, the main control unit 120 uploads the input video and audio data to a computer communication network such as the Internet through the fax / modem 130 (S113). Then, the homeowner outside is connected to the computer communication network using a remote computer 320 such as an office or a nearby PC room, and uploads video and audio data uploaded to a predetermined position of the computer communication network to the remote computer 320. By downloading and playing back in real time, you can quickly check the status of the house. At this time, it is preferable to input a unique password to confirm that the owner (S114 ~ S115).

As described above, the present invention utilizes general PC and computer communication installed and operated in a unit of a private house to detect and alarm various situations such as gas leaks, fires, and intrusions of thieves in the house, and to notify and fax telephones to designated places. By providing the relevant video and audio information in real time to other computers outside the transmission, it is possible to efficiently perform crime prevention and disaster prevention of each home.

As described above, according to the crime prevention / disaster prevention system using a computer communication and the control method according to the present invention, by using a general PC and computer communication installed and operated in a unit of a house, It effectively detects and alerts to various situations such as infiltration, provides telephone notification and fax transmissions to designated places, and provides relevant video and audio information to other external computers in real time, effectively performing crime prevention and disaster prevention for each home. There is.
