Description

Standalone Multi Video Surveillance System

The present invention relates to a technology for more easily monitoring multiple zones using a closed circuit TV (CCTV), in particular, each surveillance zone stored in a plurality of storage devices by connecting the main video storage devices on the video surveillance system through a network protocol Stand-alone multi-video surveillance system that systematically expresses video information of the system or stores it in another storage device, and virtualizes the video display device to eliminate space and time constraints in monitoring each surveillance zone through multiple storage devices. It is about.

Closed Circuit Television (CCTV) systems are not free from the point of privacy infringement, but they are becoming more and more prevalent as they contribute to the protection of personal and public property and circumstances, and to prevent accidents and crimes.

In general, a multi-image surveillance system using CCTV includes a plurality of cameras (eg, CCD cameras) for monitoring each zone, a display device for outputting images captured through them, and a storage device (recorder) for storing image signals. . By using such a multi-image surveillance system, a user can monitor several zones and use the stored image as evidence for a crime or accident.

Recently, various kinds of accidents are frequently occurring, and a video surveillance system capable of conveniently monitoring a wider area is required in order to respond appropriately.

Prior art video surveillance systems include one or more storage devices and a separate display device each connected to each storage device. In addition, a separate program using a computer network was used for remote video surveillance, device status check, and device setting.

However, since the video surveillance system according to the related art is configured in a different form from the user interface of a device that a real user encounters, if a failure occurs in a remote place or wants to educate the user, it is necessary to visit the site to solve the failure or face the user. Therefore, there is a problem in accordance with the inconvenience and costly and time-consuming. In addition, the video surveillance system according to the prior art requires a separate display device, each of which requires a lot of space in the display characteristics, there is a problem that takes up a lot of space.

The technical problem to be solved by the present invention is to allow CCTV surveillance and storage devices to share or control the mutual image and user interface screen, to efficiently configure the number of display devices used for the surveillance and storage devices, a plurality of systems To reduce waste of space and reduce system configuration costs.

Another problem to be solved by the present invention is to identify and resolve a failure of a device through a network and to educate a user as a follow-up measure when trying to identify or troubleshoot a remote storage device.

Another problem to be solved by the present invention is to build a multi-stage monitoring system that can monitor whether the monitor arbitrarily checks, processes and leaks the stored image for the purpose of the individual in the system for monitoring a plurality of storage devices.

The independent multi-image monitoring system according to an embodiment of the present invention for achieving the above technical problem, the master recording to perform a control operation for storing or displaying the image data supplied from the outside, or read and display the already stored image data Device section; Under the control of the master recording device unit, a master screen sharing unit for transmitting the video data received through a remote connection to the master recording device unit; And a slave screen sharing unit which receives the screen image supplied from the outside, receives image data of the camera connected to the recording device, and then combines the data obtained through the virtualization operation and transmits it to the master screen sharing unit. .

The independent multi-image monitoring system according to another embodiment of the present invention for processing the technical problem, and processing and storing the image data supplied from the camera, displayed on the monitor, and equipped with a screen sharing system and a mouse or keyboard A master recording device having a recorder for using the screen sharing system using the same user interface, and a slave recording device for processing and storing the image data supplied from the camera, the master recording device is a user request According to the present invention, the slave recording apparatus may request image and screen data to be displayed on a monitor, or remotely manage the slave recording apparatus when a failure occurs in the slave recording apparatus or technical support is required.

According to the present invention, a master storage device and a slave recording device are interlocked so that a user can remotely locate a device located remotely by using a multi-display display system or a screen sharing system in a CCTV surveillance system configuration. By allowing the user to check or set the image in real time, such as directly operating, there is an effect that can be more conveniently managed at a lower cost.

In addition, by using the warp monitor protocol of the present invention, it is possible to share the output of the monitor of the master device to the monitor screen connected to the slave device, so that the administrator or service personnel can troubleshoot without visiting the remote user. It is possible to reduce the management time and cost by enabling solution and training work.

In addition, the present invention can detect the operation related to the infringement of the personal information of the monitor for monitoring each storage device and the image connected thereto, thereby preventing the unauthorized leakage of personal information.
