Edge Server Camera Control for Emergency Image Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of managing network load when utilizing images from geographically distributed surveillance cameras in real-time for crime prevention and investigation is significant, as transmitting large amounts of image data increases network congestion.
Innovation Solution
An edge server and management apparatus are implemented with processors to receive emergency state information, control surveillance cameras, and transmit images to an external apparatus via a core network, enabling real-time utilization of captured images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If images from all surveillance cameras are transmitted through the network in real time, then real-time utilization of captured images is improved, but network load increases greatly causing congestion
Solution Approach 1:
The patent applies local quality by transmitting images only from surveillance cameras located in the specific area where an emergency has occurred, rather than from all cameras in the system. The management apparatus identifies the geographic location of the emergency and selectively activates only those cameras within that location, thereby providing real-time images of the incident while minimizing network data transmission volume.
2Adaptability or versatility
If surveillance cameras are geographically distributed to cover more areas, then crime prevention and tracking capability is improved, but network management complexity increases
Solution Approach 1:
The patent introduces a management apparatus as an intermediary between the geographically distributed surveillance cameras and the external utilization system. This management apparatus maintains a database mapping camera locations to geographic areas, and automatically selects appropriate cameras based on emergency location information. This intermediary layer simplifies network management by centralizing the selection logic, allowing the system to scale to multiple geographic areas without proportionally increasing management complexity.

AI summary
An edge server executes reception processing, control processing, and image transmission processing. The reception processing is for receiving, from a base station that has detected an emergency state, information indicating the emergency state via a core network connected to the base station. The control processing is for controlling, upon receiving information indicating the emergency state, one or more surveillance cameras connected to the base station. The image transmission processing is for transmitting images captured by the one or more surveillance cameras to an external apparatus via the core network.
