Such DVR has various selection menu functions such as motion detection function, sensor utilization function, connection recording function, camera operation (Pan / Tilt / Zoom / Control) function and image magnification / editing function. It is equipped with the function to keep it. In addition, the stored video can be searched by camera, event, as well as by time, date, and has evolved to provide surveillance information from a remote location.

1 is a configuration of a general remote surveillance system, which is connected to one or more surveillance cameras and microphones and various sensors, collects and outputs video / audio information and sensor information provided by them, and provides a control signal externally. Surveillance information generation and processing unit 10 that provides a control signal for receiving and controlling them, and in some cases provides an alarm to a speaker, and a video / audio signal provided from the surveillance information generation and processing unit 10 and various kinds of sensors. The remote monitoring device 20 converts the state information into a digital signal, stores the converted state information, and transmits a part of the stored monitoring information to a main communication network or a bypass network according to a power source and a communication network state. Receives the monitoring information through the main network and bypass network to determine whether or not the abnormality of the monitoring target in real time After the identification is made to the center server 30 to perform the appropriate processing in the event of an abnormality. The center server 30 serves as a control station that manages a plurality of remote monitoring devices at a remote location, and when a problem occurs, the center server 30 notifies the police station or the security company and notifies the fact to the user who requests the monitoring of the monitoring object by voice or text. .

Referring to the configuration of the remote monitoring device 20, the video / audio processing unit 21 for receiving the video / audio signal provided by the surveillance information generation and processing unit 10 to make the appropriate digital video / audio information, and A monitoring signal processing unit which receives the sensing signal provided by the monitoring information generating and processing unit 10 to make appropriate digital information, and transmits the control information requested by the control unit 24 to the monitoring information generating and processing unit 10 when necessary; 22, a surveillance information storage unit 23 for storing the digitized surveillance information (video / audio information and sensing information) in a predetermined storage means, the video / audio processor 21, and a surveillance signal processor 22 ) And a monitor configured with a modem suitable for various communication networks by selecting some of the monitoring information stored in the monitoring information storage unit 23 while controlling the monitoring information storage unit 23.

It is changed to the armed / disarmed state according to the state of the DVR 120 for transmitting to the central control unit 200, and the sensor unit 112 for detecting a specific external environmental change and changes the state of the DVR (120) It consists of a security control unit 110 to provide and to operate a particular control means (e.g., warning lights, alarms, alarm devices, etc.). In the above embodiment, the DVR 120 having an image related processing function and a remote control related function is coupled to a security control unit 110 which is widely installed at the present time, and when the event occurs as mentioned above, central control thereof is facilitated. It is configured to further add a function to automatically provide the specific information to the central control unit 200. Through this, the central control unit 200 can immediately check the information when the event occurs when necessary.

Of course, the configuration is a configuration for extending the function while effectively utilizing the unique security monitoring function and related control system of the security control unit 100 is widely spread in the transitional configuration, which can be variously changed. For example, by connecting sensors for detecting environmental changes to the security zone to the DVR 120 to which the function should be added to provide information according to the event occurrence, to detect the event occurrence, or to move through the camera 121 In the case of adding a function such as sensing an event to be detected or utilizing a corresponding function, the security controller 110 may be configured to be excluded.

The DVR 120 has a function of providing a video and event generation information to the central control unit 200 in addition to a web server function for remote monitoring to connect the client terminal using the Internet or LAN and remotely by the client terminal. Control and monitoring (channel selection, camera operation (PTZ) control, playback related operations) can be enabled. In addition, in order to support mobile remote sensing, which is rapidly emerging, the DVR 120 converts a digital image stored in accordance with the resolution of the mobile communication terminal 320, which is a mobile terminal, and provides the same to the mobile communication terminal 320. It can have a function.

In order to configure the system so that the subscriber stations (310, 320), or the central control unit 200 can remotely control the DVR 120, the web server configured in the DVR 120 is point-to-point It is desirable to support a point-to-point connection and a file exchange information exchange function.

In addition, for the remote control and remote monitoring of the DVR 120, the central control unit 200, the subscriber terminal (310, 320) that requires the function to receive the video and the function to access the DVR 120 And a dedicated application capable of transmitting a function of reproducing and transmitting various control requests according to a user's request. In the case of the central control unit 200 or the personal computer 310, a dedicated program can be obtained and installed through various paths, or a predetermined program module (ActiveX, OLE, etc.) can be downloaded and installed through a web connection. In the case of the mobile communication terminal 320, the program can be obtained and installed directly through various paths, or the program can be downloaded and installed through a mobile web server. For example, when the mobile communication terminal 320 is a mobile phone, an application composed of a Java application that can be operated in a Java virtual machine configured in the mobile phone may be applied.

The DVR 120 may have a fixed IP address, but in many cases it is highly likely to be used in an environment in which IP is flexibly assigned. Thus, the DVR 120 may be registered with the DDNS 160 to register the DVR 120. Even if the IP of 120 is changed, IP information of the DVR 120 is provided to the subscriber station 310 or 320 or the central control unit 200 so that it can be connected as if using a fixed IP. In addition, the DDNS 160 may perform an authentication process for subscribers as well as information on the IP, and for this purpose, the DDNS 160 may have access to a subscriber information database (not shown). The subscriber information database may be configured in the central control unit 200, the DDNS 160, or a separate server, and in any case, the DDNS 160 and the central control unit 200. At least one of the In general, it is preferable that both the DDNS 160 and the central control unit 200 are accessible.

The central control unit 200 may be physically configured with various interfaces for providing security information to the servers installed in the control room and the administrator managing the same, as shown in the subscriber terminals (310, 320) Means for providing security related information in a predetermined message state (for example, an email transmission means, an SMS transmission means or an MMS transmission means, etc.). Taking the illustrated configuration as an example, at least one or more of various configurations such as a center server, an e-mail server, an SMS transmission server, a subscriber information database server, and an event information storage database server may be combined.

As briefly mentioned above, the central control unit 200 receives image sets linked with the event related information provided by the DVR monitoring unit 100, stores the corresponding information, and displays the information on a single screen to facilitate the administrator. The security status can be managed based on the event-related information, and the function of delivering the relevant information to the subscriber is also performed. In particular, the contents related to the new interface expressing the event-related information and the image sets in the central controller 200 will be described in more detail later with reference to FIGS. 7 to 8.

FIG. 6 is a block diagram illustrating an example of the central control unit 200. As shown in FIG. 6, event information and video information provided from the DVR monitoring unit 100 are received and the DVR monitoring unit 100 is controlled. Transmitting and receiving unit 210 for transmitting information, the event information database unit 260 for interlocking and storing the provided event information and image information, and based on the DVR monitoring unit 100 information included in the event information A customer information database unit 230 for acquiring customer information, a display unit 240 for displaying log information including the event information and customer information, and a series of image sets linked to the corresponding event; Interface unit 250 for managing the operation, and if necessary, direct control of the DVR 120 of the DVR monitoring unit 100, search and playback of the stored video, and various types of control allowed by the DVR 120 Live to provide an interface for null selection, control for position or status adjustment (Pan / Tilt / Zoom) for selected cameras, control requests for other devices (such as beacons, lights, etc.) connected to the DVR 120 And an image interface unit 270 (application portion for controlling the DVR 120 described above). In this case, the customer information database 230 may be configured separately from the central control unit 200, it may be configured in the DDNS (160).

The central controller 200 may further include an email transmitter 280 or an SMS transmitter 290 for providing an event situation to the subscriber terminal. The email sending unit 280 or SMS sending unit 290 may each have a server configuration that completely performs the corresponding function, but means for generating a message for requesting such a task to a separate server that provides the corresponding function. It may be.

Now, a description will be given of the manner in which the central controller 200 provides the event occurrence related information to the subscriber stations 310 and 320.

The central controller 200 transmits at least some information of the video set and event occurrence information to the subscriber through one or more message methods such as e-mail and message service (MMS, SMS), wherein the information is transmitted to the information method. It is preferable to further transmit the remote access link information for the DVR monitoring unit. Through this, the subscriber stations 310 and 320 check an image together with an event occurrence situation, and if necessary, access the DVR monitoring unit 100 by a remote control method through the remote access link information to check a desired image. Will be. In particular, if the remote access link information further includes information for starting playback from an event occurrence time, it is possible to easily monitor the situation after the event occurrence, which is a main concern.

If the user terminal is the mobile communication terminal 320, the video may be provided through the MMS method, but rather, the mobile monitoring using the mobile communication terminal of the subscriber while notifying the event occurrence information and related information using the SMS method. The access address for using the function may be provided as the callback URL information. The callback URL information may be an address of an access screen of the DDNS 160 when using the mobile monitoring function through the DDNS 160, or may be any web page relaying access to the address. For example, to include the address of a web page (or mobile web page) specific to the text message (SMS) as callback URL information, and to operate an application installed in the mobile communication terminal 320 on the specific web page. By inserting a code so that the user can check the surveillance image of the DVR 120 through the web server function configured in the DVR 120 only by checking the text message. If necessary, the web page may process authentication for the user, and the authentication information may share information registered in the DDNS 220.

If the central controller 200 transmits at least some of the video set and event occurrence information by e-mail, the e-mail includes a direct connection link to the DVR 120 or the DDNS 160. Access link may be included, and if an independent web server is built in or interlocked with the central control unit 200, after configuring a web monitoring function and subscriber authentication function for the DVR 120 in the corresponding web server Links may be included to take advantage of this.

FIG. 7 illustrates an example of a central control interface 400 configured in the central control unit 200, and is configured to enable the administrator to effectively manage a large number of subscriber DVR monitoring units.

As shown in the drawing, the central control interface 400 includes a log area 420 that displays log information 430 configured by using event occurrence information and subscriber information based on the event occurrence information, and is currently selected. The sensing image display area 410 displays a series of image sets received in association with the log information 430. Although the illustrated configuration includes a single screen, the configuration may be distributed over a plurality of display areas. However, each of the regions 410 and 420 should be linked to each other so that an administrator can check information related to an event occurrence and subscriber information at a glance, and image information about a situation before and after the event occurrence time.

In the illustrated configuration example, when the DVR monitoring unit provides 10 consecutive video sets together with event occurrence information when an event occurs, the preceding 2 videos among the 10 continuous videos are images before an event occurs, and subsequent 8 The video is composed of the video after the event occurs. The extraction method of the images is preferably extracted by a predetermined time unit, which can be set in the DVR monitoring unit or the central control unit. For example, each of the images may be about 0.1 to 0.5 seconds in consideration of human motion. Alternatively, ten frames may be extracted in a storage frame order. The number and division method of the image may be variously changed, and change setting may be possible. In particular, the number of events and the event information may be changed according to each classification by dividing the case of an event by a simple schedule setting and the case of an event occurring in a specific security threat situation according to the type of event. Through this, the administrator can easily distinguish between the occurrence of events due to the daily schedule and the occurrence of the events due to the security threat situation, thereby improving management efficiency.

The log information includes at least one of device information, time information, monitoring zone information, subscriber information, access IP, and DDNS server information of the DVR monitoring unit (or DVR) that reported the event occurrence. In the log area 420, one line or one unit area is preferably displayed. Through this, it is possible to determine a more specific security situation by using the log information 430 displayed continuously.

For example, in the illustrated case, since an event is continuously generated for a specific customer's security area, and the security area where the event occurs is moving, it can be estimated that an intruder is present. In this case, when the log information 430 is selected, image sets corresponding to the log information 430 may appear in the surveillance video display area 410, thereby making it possible to more securely determine the security situation. This is because when the log information for a large number of subscribers is continuously displayed, if the log information cannot be checked in real time, even if specific log information 430 is checked at a time deviated from the time when the actual event occurs, the surveillance image display area In operation 410, an image of a time point at which an event occurs is provided to determine whether the security region is abnormal based on the image.

If a doubt is found through the provided video sets, the administrator may perform a deep monitoring by executing a live video interface to the corresponding DVR monitoring unit through the selection of a predetermined menu or an image.

FIG. 8 illustrates an example of a live video interface 440. In a particular situation, a live video interface 450 provided by a DVR of a selected DVR monitoring unit may be checked, and desired information may be obtained by controlling the live video 450. In addition, if necessary, the DVR may control channel setting, camera control, and external control signals through the means provided by the DVR. In particular, the live video interface 440 is preferably executed in conjunction with the log information for a faster and more accurate security status check. For example, when the live video interface 440 is driven after selecting specific log information, the stored video may be played back from the time of occurrence of the event using information related to the time of occurrence of the event. The live video interface 440 may be configured to play an image of a viewpoint.

Through the above configuration, it is possible to collectively manage a large number of DVR monitoring units in an easier manner, and greatly reduce the erroneous judgment regarding the omission or security status. In addition, through the subscriber information transmission function described above, the subscriber can also know the event occurrence situation in real time, thereby greatly increasing the reliability of the security.

FIG. 9 is a flowchart illustrating an example of a remote monitoring process using the remote monitoring system. As shown in FIG. 9, a predetermined event is generated while the DVR monitoring unit acquires and stores an image while checking an environment change of its security area. When this occurs, the event information and the video set of the specified configuration are transmitted to the central controller.

The central controller, which has acquired the event occurrence information and the related video set provided by the DVR monitoring unit, generates log information including subscriber information based on the corresponding event occurrence information to display a part of the interface provided by the central controller for image control. If a specific log is selected, an image set corresponding to another display area of the corresponding interface is displayed. The event occurrence information (or log information) and the image set are stored during or after the process.

If the notification function for the subscriber is set when the event occurs, or if the administrator analyzes the event occurrence content and deems it necessary, the information is transmitted to the subscriber terminal. Event occurrence information provided to the subscriber terminal can be applied to a method that can easily utilize a variety of applications while being easily accessible to most subscribers, such as e-mail basically. If a mobile monitoring function is set for the subscriber, the video and event occurrence information may be simultaneously provided using MMS, and an SMS message including callback URL information may be used. Through this, the subscriber can access the DVR monitoring unit in a remote manner and acquire the surveillance information related to the event.
