Abstract

PURPOSE: A DVR(Digital Video Recorder) system building an alarm transmission function therein by using an Internet phone is provided to input an image from a camera, and to sense whether an invasion occurs from the inputted image, then to inform a manager of the invasion, so that the manager can quickly cope with the invasion. CONSTITUTION: A DVR system(36) comprises a video decoder and a video encoder for inputting/outputting an image, an SDRAM and a hard disk for storing image data and programs, a video encoder and a video decoder for compressing/restoring the image data, a multiplexer for controlling image data by channel, and a PCI controller for driving/controlling with a PC. The DVR system(36) inputs the image through a camera(31), and monitors/stores the inputted image. A motion detection unit(35) detects a motion in a designated area. An Internet phone(34) is a dedicated program for using an Internet phone service.

Description

DVR system with a built alarm transmission using VoIP phone}

The present invention relates to an apparatus and method for a DVR system incorporating an alarm transmission function using an internet telephone that can be appropriately dealt with by being delivered to an administrator when an intrusion situation occurs in a place where a DVR system is installed. will be.

In the related art, an administrator displays and monitors an image displayed on a screen by a DVR system where the DVR system is located, and takes an action when an intrusion situation is found.

In addition, when the manager is located at a long distance, as shown in FIG. 2, the DVR system 21 is connected to a communication network 22 capable of remote access, and the manager's PC 25 is connected to the monitoring site 24 through dedicated software. Monitor the video.

Therefore, the administrator must always monitor the video, there is a problem that does not detect the intrusion situation when the inefficient use of manpower and the manager's neglect of monitoring.

The present invention was devised to solve the above problems, and when an intrusion situation occurs in a specific place, the administrator can deliver the emergency situation by using the Internet telephone, so that the administrator can quickly deal with the problem while performing other tasks. An object of the present invention is to provide an apparatus and method for a DVR system having an alarm transmission function using an internet telephone.

In order to achieve the above object, the configuration of the DVR system in which the alarm transmission function using the Internet phone of the present invention is incorporated is composed of a DVR system unit 36, a motion detection unit 35, and an Internet phone unit 34.

Hereinafter, a configuration and an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a block diagram showing the internal configuration of the DVR system with built-in alarm transmission function using the Internet phone according to the present invention.

Referring to FIG. 3, the DVR system 36 includes a Video Decoder for inputting / outputting an image, a Video Encoder, an SDRM for storing image data and a program, a Hard Disk, a Video Encoder for compressing / restored image data, a Video Decoder, It consists of a multiplexer that controls the image data for each channel, and a PCI controller that drives and controls it with a PC, receives an image 31 through a camera, and monitors and stores the input image.

The motion monitoring unit 35 designates a specific area so that the user detects only the movement occurring in the designated area, and the user may arbitrarily set the sensitivity of the motion.

The Internet phone book 34 is a dedicated program for using the Internet phone service. In this case, the Internet phone service refers to a communication service that delivers voice, fax, voice messages, etc. using an internet network instead of an existing general telephone network. In the present invention, it is used for the purpose of transferring the voice message between the DVR and the general telephone.

4 shows a communication method of a DVR-to-general telephone as described above, and a call is established between a DVR and an administrator via a gateway that follows the H.323 standard of a general telephone using an Internet telephony program embedded in the DVR.

An example of the operation of the DVR system according to the present invention is shown in FIGS. 1 and 4, and when a movement is detected in the DVR system, an alarm message containing the contents of an intrusion situation is transmitted to an administrator's phone through an Internet dedicated network and a gateway.

In the operation process as shown in FIG.

A first step (51, 52) of logging in to the DVR system and initializing;

A second step (53, 54) of grasping the movement of the external intruder from the DVR system;

A third step (55, 56) of transmitting an alert message to a registered manager's phone by using an internet phone when an intrusion situation is detected;

When the administrator confirms the forwarded message, the system performs the fourth step 57 and 58 to record and terminate the above system operation.

As described above, the DVR system incorporating the alarm transmission function using the Internet phone according to the present invention minimizes the load of the administrator required to monitor a specific area and prevents the administrator from neglecting the monitoring function of the DVR while performing other tasks. For example, even if the manager is located far from the monitoring area, the alarm message is sent to other managers in close range so that they can respond quickly in case of problems.

As a result, the stability of security surveillance is improved, and the manager does not always monitor the video, thereby increasing the efficiency of manpower use.

It also has the advantage of reducing communication costs by using an internet phone to deliver alert messages to the manager phone.
