Description

Video surveillance apparatus supporting optimization for operating environment of camera and operating method of the same}

The present invention relates to a video surveillance apparatus for supporting optimization of a camera operating environment and a method of operating the same, comprising: a video surveillance apparatus and a camera managing a video of the camera by communicating through a communication network composed of a plurality of cameras and one or more network devices It is composed of a communication network to support the optimization of the video surveillance system by applying the optimal settings of the existing camera to the replaced camera when replacing the camera that needs to be replaced in the video surveillance system optimized during the initial design The present invention relates to a video surveillance apparatus that supports optimization of a camera operating environment and a method of operating the same.

Today's CCTV cameras and systems are more advanced than the past analog transmission methods, and the hardware (H / W) or software ( Failure rates, such as freezing of S / W), are also rising compared to the past.

In addition, analog cameras and storage devices of the past have a 1: 1 connection configuration concept regardless of size, and there is no change in complexity according to the scale, while a camera processing a network high resolution (more than 1 million pixels) The video surveillance system is composed of the network part in charge of the transmission part according to the size, the specification of the traffic load to be processed per hub needs to be configured and the system configuration is not only necessary, but also the configuration parameters between the camera and the storage device As system complexity increases with increasing system complexity, such video surveillance systems must be managed by design and setup by skilled engineers.

In other words, if the load of the entire system is incorrectly designed or the setting optimized for the design is not performed, frequent loss of video (LOSS) may occur and the main purpose of the video surveillance system may be lost depending on the frequency of occurrence.

For this reason, the video surveillance system is designed by an experienced administrator to ensure the quality of the system and is operated with optimized system settings, which includes the quality of the video itself (resolution, frame, etc.) and the operation of the system. Include quality of care.

However, even if it is designed and set up and started to operate normally, repairs due to errors or defects that occur later may occur.

At this time, when the failed equipment such as the camera constituting the video surveillance system is replaced to maintain the system, the repair should be performed while maintaining the setting corresponding to the optimized system. Or failure to occur during the replacement of faulty equipment, such as a simple replacement by an inexperienced engineer, resulting in a problem that the existing optimized system state is not maintained. Can lead to degradation.

In the past, the analog system does not require consideration of the configuration of the replaced device even when the camera is replaced. However, the newly installed camera is a high resolution network applied to a network-based video surveillance system. As cameras dominate, there is a need for camera setup considerations that can maintain an optimized system state at the time of design as described above.

However, even experienced managers are often replaced with managers different from those at the time of design, making it difficult to grasp the overall configuration of the system. I'm having a hard time changing my camera.

In addition, since most of the systems using analog cameras are still difficult to hire, it is difficult to hire specialists for system optimization. Therefore, the time required for hiring these specialists is considerable. In addition to the damages caused by this problem, there is a significant problem even in the case of hiring professional personnel, in order to diagnose the problem system components and to come up with a solution.

Therefore, in operating the network-based video surveillance system, the system itself can be diagnosed and provide information on the equipment or section where the failure occurred without the help of specialists, while maintaining the existing optimized system status when replacing the equipment. Alternative developments are required.

In addition, the controller 170 may determine whether the estimated load amount according to the load change for each of the associated network devices exceeds the limit load amount set in the device information.

In addition, when the control unit 170 determines that at least one associated network device exceeds the threshold load, the controller 170 generates control information generated based on the basic profile and transmits the generated control information to the specific camera to set up the camera of the specific camera. If the prediction load is less than the threshold load in all associated network devices, the configuration information (current configuration information) of the specific camera may be maintained without generating the control information.

That is, when the traffic generated from the specific camera is a load that can be accommodated while maintaining the optimized state of the communication network according to the configuration information of the specific camera reconnected or newly connected to the communication network, the specific camera.

As illustrated in FIG. 6, the controller 170 may be configured based on a threshold value for each of a minimum bandwidth and a maximum bandwidth preset according to a user input and the number of ports of one or more network devices to which the camera is connected based on the topology map. Accordingly, in each case of the minimum bandwidth and the maximum bandwidth, the number of connectable cameras can be calculated.

In addition, the controller 170 when the bandwidth of the load change calculated based on the topology map to which the specific camera is applied when replacing the existing camera used when generating the basic profile with the specific camera exceeds the maximum bandwidth; According to the camera information according to one or more other cameras connected to the communication network and the number of the cameras, the camera can maintain the camera settings according to the setting information included in the camera information of a specific camera.
