It is possible to visually recognize the contents stored in 28 and various information (video and text information, etc.) transmitted from the central control system 4.

In addition, since the two-way wireless terminal device 2 is also provided with a voice signal output unit 30, the administrator of the central control system 4, which recognizes the occurrence of an emergency situation, including the invader's occurrence, sends a specific message or the like. If the voice is sent through the speaker 32, such a situation can be notified to people around the subscriber's home, including the execution of warning broadcasts for intruders.

On the other hand, the central control system 4 includes several monitors or terminals 41, etc. necessary for video, alarm and interception, and although not shown, intrusion, emergency signal processing, and alert, release, intrusion, emergency, Decoder which decodes sensor signal in consideration of inspection, disconnection check signal processing, subscriber database management, situation database management, scalability / stability, an alarm generator which analyzes output signal of decoder and generates alarm in case of intrusion; Customer management department that retrieves customer information that has occurred intrusion situation and changes, deletes, or adds the customer's information when changing customer information, database server that stores customer information and alarm situation information Backup server that performs the corresponding function at the time, broadcast and alert for on-site sound Government, the router to interface the image and data signals transmitted through the Internet network, the video surveillance server to store the image transmitted from the router and display it on the screen and to notify subscribers and crime prevention authorities through the public network Subscriber contact unit and the like, which is already known in the art so that the illustration is omitted.

Accordingly, in the central control system 4, various wireless terminal sensors in a specific subscriber's home through the Internet network 3 in a state of being interconnected with two-way wireless terminal devices 2 of multiple subscribers through the Internet network 3 as usual. When a predetermined detection signal is transmitted from (1), it analyzes and displays it, recognizes customer information in case of an intrusion situation, and listens to the on-site sound and broadcasts the alert through the public network (5). This can be promptly notified by promptly notifying the government (6) related to security (security).

As described above, according to the present invention, a disconnection detection signal including a detection signal of an intruder transmitted from various sensors installed in a subscriber's house, field sound, and various data information (including image information) are received through a wireless network. The system can be notified to the control system through the Internet network, thus integrating the wireless network, the public network and the Internet network to perform the security function, thereby ensuring the reliability of the security system itself, and using the Internet network to the existing telephone leased line method. Compared to this, it can significantly reduce the product price and operation cost, and also solve the biggest problem of disconnection and its undetectable problem, which is caused by security devices using existing telephone aerials, and provide subscribers with Internet dedicated line in addition to simple security service. It can provide more various services. .
