Virtual Matrix System and Control Method

The present invention relates to a virtual matrix system and a control method. In particular, it is possible to easily control hundreds of camera images, which are installed in a small scale from an apartment or a building to a national scale, in a central control room.

In general, a matrix is a device that receives images from a plurality of CCTV cameras and displays the images in a cross-point switch method on a plurality of monitors.

In other words, the matrix system has a large number of input and output terminals so that the video signal of the input CCTV camera can be arbitrarily output to the desired monitor according to the preference of the system administrator, regardless of the predetermined order, and the matrix system can be expanded according to the installation scale of the CCTV camera. It can be reduced and configured.

The conventional matrix is not only expensive but also reveals its limitations in installation and use in various parts such as scalability, economy, and operational convenience in an increasingly large CCTV camera market.

In addition, in the case of the conventional matrix system, the number of CCTV cameras that can be connected is limited, so if the number of installed matrix cameras is exceeded, new CCTV cameras cannot be added or additional expensive matrix equipment can be added. There was a burden to buy.

In addition, in the past, when a system is in use, equipment specifications become outdated and need to be replaced or added, and it is very difficult to change or add equipment in a matrix composed of existing hardware.

In the case of the conventional matrix system, when the image is taken with a CCTV camera in a certain area, the place where the image is received and viewed by the monitor is limited to the corresponding control station, and if the user wants to view such image elsewhere, the image is copied and transmitted separately. I had to.

In other words, the video recorded by CCTV cameras installed in a certain area can be viewed only by the manager of the control room. There was no at all.

For example, if many CCTV cameras are installed and operated at police box in area A, and CCTV cameras are installed and operated at local government in area B, if an incident occurs in area A, it is installed at police box in area A. You can monitor and view the video through CCTV cameras, but if an incident occurs in the B area, you cannot see the CCTV camera video of the B area directly at the police box. Or I had to go to see it directly.

In other words, multiple monitors could not be monitored at once, and in the existing matrix, it was a passive position that requires the direct connection of lines.

Fig. 1 shows a conventional DVR configuration based on 16 channels, wherein an analog CCTV (1) is installed in a field, and this CCTV (1) is connected to a digital video recorder (2) and a monitor (3) of a control room through a coaxial cable.

There was.

In addition, coaxial cable was additionally needed for the expansion of the camera, and additional equipment was required if the control channel matrix channel could not be afforded, and a separate program was required due to the difficulty of adding a new camera to the operating system.

Figure 4 shows the configuration of a conventional large-scale hybrid DVR system, a number of analog CCTV cameras 1 are installed in the field, such a video server (4), switching hub (5) and digital video respectively in the CCTV camera (1) In addition to installing the recorder (2), it was necessary to install a KVM (6) and a plurality of monitors (3) that can control these digital video recorder (2).

In such a large-scale DVR system, many DVRs, matrix equipments, equipment control systems, and system control KVMs were required. In the case of a system composed of hundreds or more, a comprehensive control room is not only very difficult, but also limited by the distance of the control area. Received a complicated problem of control system configuration.
