Video Management System Dynamic Zooming for Surveillance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video management systems face challenges in allowing operators to efficiently and intuitively switch between relevant views, requiring familiarity with surveilled areas and views, which hinders quick and accurate monitoring.
Innovation Solution
A video management system that organizes monitoring devices as a network of nodes with logical connections, introducing a neighbor monitoring level to enable efficient zooming in and out by adding or removing views, allowing operators to predictably switch between different levels of detail and overview.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple video streams are displayed simultaneously on a single monitor using split screen configuration, then the operator can get a better overview of surveilled areas, but the level of detail in each view decreases
Solution Approach 1:
The system dynamically adjusts the display configuration between single camera view and multiple camera views based on operator input. The partitioning of the monitor is not fixed but can be changed on demand, allowing the operator to switch between detailed single-camera monitoring and overview multi-camera monitoring as needed.
Solution Approach 2:
The patent introduces a temporal dimension to the display switching, allowing operators to transition between different viewing modes (single camera vs. multiple cameras) over time. This enables the system to provide both detailed views and overview capabilities by sequencing different display configurations rather than presenting them simultaneously.
2Adaptability or versatility
If the operator needs to switch between different views to track targets moving between monitored areas, then the monitoring coverage increases, but the operation complexity and time required increases
Solution Approach 1:
The system pre-arranges multiple camera views in a split-screen configuration, so that when the operator needs to track a target moving between areas, the relevant camera feeds are already positioned and ready for immediate viewing. This eliminates the need for sequential switching and allows simultaneous monitoring of multiple potential target locations.
Solution Approach 2:
The patent combines multiple camera views into a single integrated display showing several surveillance areas simultaneously. By merging the views in a split-screen layout, the operator can track targets moving between areas without switching displays, as all relevant feeds are presented together in one view.
3Measurement precision
If the system requires the operator to be familiar with surveilled areas and available views for efficient operation, then the viewing precision improves, but the ease of operation decreases
Solution Approach 1:
The system automatically manages the display configuration and camera selection based on operational needs, reducing the burden on the operator to manually configure views. The split-screen arrangement and camera feeds are self-organized to provide both overview and detail capabilities without requiring the operator to extensively configure or navigate complex view settings.

AI summary
A video management system for displaying video streams from a plurality of monitoring devices arranged in a network in a video display arrangement. Each monitoring device constitutes a node in the network and has a logical connection to at least one other node. The video management system is configured to: in response to a first input, zoom out from a first subset of views from a first monitoring device or a first group of monitoring devices to a second subset of views, by adding views from a predetermined number of monitoring devices having a direct logical connection to the first monitoring device or the group of monitoring devices, to the video display arrangement, thereby increasing a neighbor monitoring level by one; and in response to a second input, zoom in from the second subset of views thereby decreasing the neighbor monitoring level by one.
