The system of both selectively remote controlling of CCTV camera and dynamic grouping monitoring by user demand and the mehtod

The present invention relates to a selective remote control and dynamic grouping monitoring system of CCTV cameras and a method thereof, which simultaneously controls a plurality of CCTV cameras in a group and remotely controls a CCTV camera installed for security and security. System and method that can be monitored in combination.

Recently, various systems have been proposed for security and security as society changes rapidly and various incidents occur. For this reason, various methods using a security camera, that is, a CCTV system, have been developed. However, only one to several cameras connected to a field video recording device provide a simple recording function.

Therefore, the manager could not manage for a long time, or there was no way to group a group of cameras in a window at a certain point of time among the ten CCTV cameras.

In order to solve this problem, video can be checked from a long distance, and methods for remotely controlling DVR (Digital Video Recorder) in a network environment have been developed, but most of these remote control methods are unique to each remote DVR system. After downloading and installing a media player capable of playing video through the Internet, most of them could simply view real-time video contents. In this case, a large video stream is transmitted to a streaming server, and the streaming server compresses and stores the video stream into a file and transmits it to a network. This process requires tremendous network bandwidth and storage.

In addition, in such a system, since only one to several cameras installed in the same area can be controlled, there is a problem that it is difficult to selectively control or monitor cameras installed in several places at the same time.

In addition, since only a specific administrator has access to the video, there is a problem in that it is not open to the general public or an unspecified number, and thus it is not easily accessible to those who need to manage other videos.

In order to overcome the problems described above, the present invention integrates, stores and controls the video streams that are collectively transmitted from a plurality of CCTV cameras installed in various regions, the user wants to control The objective of the present invention is to reduce the storage capacity and load of network bandwidth by providing a system and method for selectively controlling CCTV cameras and providing a group monitoring and operation.

It is another object of the present invention to provide a control monitoring system and method for enabling viewing in accordance with security level in addition to the administrator.

It is still another object of the present invention to provide a system and method capable of controlling and monitoring a CCTV camera in a personal portable terminal in addition to means such as a PC through a computer network such as the Internet.

The present invention is connected to one or more CCTV cameras, and can encode an analog video signal recognized from the CCTV camera to a high-definition digital video signal, and VENS (Video Encoding & Network) connected to an external network for transmitting and receiving signals. Streaming) is connected to the set-top box and the VENS set-top box, manages the VENS set-top, accessor, connection, billing information, etc., and provides services related to monitoring and control of CCTV cameras to the connected user A main server and a user terminal connected to the main server through a computer network such as the Internet.

In order to provide the service, the VENS set-top box encodes an analog CCTV camera input signal into a digital signal and simultaneously provides a streaming server.

VENS set-top box video encoding software captures analog video signals, digitizes and compresses them to Flash video standards, stores and manages them on local devices, and streaming software delivers compressed video streams to the network. A user viewing this video stream on the Internet requests a connection to a CCTV camera that the user wants to monitor. When the connection is made, the VENS set-top box sends the requested video stream to the flash player of the user's computer. Users only have a flash player already installed on their computer and can receive live video streaming without installing a separate media player. Compressed and streamed video can be restored to its original size, enlarged, and played back.

By using this method, it is not necessary to have a separate large-capacity video DB server generated by integrating the video streams of all CCTV cameras into the server and storing the video as in the conventional method. By providing network traffic only on demand, users can significantly reduce network bandwidth.

In addition, although each CCTV camera is individually controlled for remote control and selective monitoring of multiple CCTV cameras, each camera can be grouped for control and monitoring to create an optimal view model. Is to be set. As a method of controlling camera, make Pan / Tilt control button on CCTV camera video screen that user wants to see similar to the existing method and click this button to send this signal to camera control line (RS 485) through VENS set-top box. You can use the method to rotate the angle of the CCTV camera by an angle determined by).

In addition, it is possible to set the public or private for the video provided by each CCTV camera, so that in addition to the administrator can be viewed in the public.

By providing such a method, the object of the present invention can be achieved.

In order to overcome the above problems, the present invention can service only the necessary video streams through the network by selecting and operating the control and monitoring of CCTV cameras installed in various regions. Therefore, the necessity of the integrated storage required in the centralized method is eliminated, and image data need to be stored in each set-top and requested and confirmed only when necessary. In addition, since all video streams do not need to be transmitted to the network, network traffic can be greatly reduced, and by introducing an open CCTV concept, the user can watch in addition to the manager, and thus can be used in various extension applications. In addition, the encoder of the set-top performs the general-purpose mobile encoding in addition to the encoding of the flash format, it is possible to control and monitor the CCTV camera in the personal portable terminal in addition to the means such as a PC through the computer network.
