Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of video analytics systems into video surveillance systems poses security challenges and complexity, especially in secure IP networks, due to the need for direct connections that can compromise network security.
Innovation Solution
Implementing display-based video analytics that perform video analytics on video streams without a direct connection to the IP network, allowing for secure integration and operation within secure IP networks by processing video streams received via a video receiving device and outputting results locally or non-locally.

Engineering Contradiction Analysis
1Productivity
If a video analytics system is directly connected to the IP network to perform real-time video analysis, then video analytics functionality is achieved, but network security is compromised and device integration complexity increases
Solution Approach 1:
The patent introduces a display device as an intermediary component between the IP network and the video analytics system. The display device receives video streams from the IP network and transmits them to the video analytics system via a display interface (e.g., HDMI, DisplayPort). This intermediary approach allows the video analytics system to process video data without requiring direct network connectivity, thereby maintaining network security while enabling analytics functionality. The display device acts as a bridge that decouples the analytics system from the network infrastructure.
Solution Approach 2:
The system is divided into separate functional components: the IP network with video cameras and VMS, the display device that receives and relays video streams, and the video analytics system that processes the video data. This segmentation allows each component to operate independently with defined interfaces, reducing integration complexity and security risks associated with direct network connections. The display device serves as an interface layer that connects the network side to the analytics side without requiring the analytics system to be network-enabled.

If a video analytics system is directly connected to the IP network, then real-time video analysis can be performed, but the integration process becomes cumbersome and security policy compliance becomes complex
Solution Approach 1:
The display device serves as an intermediary that simplifies integration by providing a standard display interface connection between the network infrastructure and the video analytics system. This eliminates the need for complex network configuration, firewall rules, and security policy compliance checks that would be required for direct network integration. The display interface (HDMI, DisplayPort, etc.) provides a simple, well-defined connection method that reduces integration complexity significantly.
Solution Approach 2:
The video stream is copied from the display device output to the video analytics system input through the display interface. This copying approach allows the analytics system to receive and process video data without needing direct network access or network protocol knowledge. The display device captures the video stream from the network and replicates it through the display interface, enabling the analytics system to operate independently from network infrastructure while maintaining real-time analysis capability.

AI summary
The present disclosure is directed to a video surveillance system and method for performing display-based video analytics on video streams provided by internet protocol (IP) cameras and/or a video management system (VMS) over an IP network. Display-based video analytics can perform video analytics on the video streams without a direct connection to the IP network. Because the display-based video analytics can perform video analytics on the video streams without being directly connected to the IP network, the display-based video analytics can be more readily implemented in video surveillance systems with secure IP networks.
