Video Collection Server Dynamic Coverage Gap Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security systems struggle to provide comprehensive and dynamic video coverage of event areas, especially where fixed cameras are not installed and wearable cameras are insufficient, leading to gaps in monitoring and response to changing situations during events like large gatherings.
Innovation Solution
A video collection system that includes a server capable of calculating imaged areas from camera data, determining additional areas needing coverage based on location, and requesting video data from terminals, such as those held by volunteers, to fill gaps and adapt to changing situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If fixed cameras and wearable cameras are used for security monitoring, then security coverage is provided in installed areas, but coverage gaps occur in areas without fixed cameras and where wearable cameras are insufficient
Solution Approach 1:
The system enables mobile terminals to serve dual purposes: as communication devices for users and as temporary security monitoring points when requested. The server dynamically identifies terminals within needed coverage areas and requests video capture, allowing ordinary mobile devices to function as security cameras. This multi-functionality fills coverage gaps without requiring dedicated fixed camera installation in every location.
Solution Approach 2:
The system dynamically adapts monitoring coverage by continuously calculating which areas need surveillance and identifying suitable mobile terminals in those areas. The server determines coverage needs based on real-time conditions and dynamically selects appropriate terminals to provide video data, creating a flexible monitoring network that adjusts to changing security requirements and terminal locations.
2Area of stationary object
If more wearable cameras are deployed to security guards, then coverage in some areas improves, but the cost and operational complexity increase
Solution Approach 1:
The system automatically performs all operations without requiring manual deployment of additional cameras. The server autonomously calculates coverage gaps, identifies suitable mobile terminals, requests video data, and integrates it into the monitoring system. This self-service approach eliminates the need for manual camera deployment and reduces operational complexity while expanding coverage.
Solution Approach 2:
Instead of deploying physical cameras to every needed location, the system creates virtual copies of camera functionality using existing mobile terminals. The server requests video capture from selected terminals and processes this data as if it came from dedicated security cameras, providing coverage expansion without the cost and complexity of physical camera deployment.
3Loss of information
If the system requests video data from multiple terminals to fill coverage gaps, then comprehensive coverage is achieved, but communication overhead and processing complexity increase
Solution Approach 1:
The server applies different processing and selection criteria to different areas based on their specific coverage needs. Rather than uniformly requesting data from all terminals, the system identifies specific terminals in specific areas that need coverage and requests data only from those local sources. This localized approach achieves comprehensive coverage while minimizing communication overhead and processing complexity.

AI summary
A video collection system includes: a plurality of terminals; and a video collection server that requests at least one of the plurality of terminals to perform information provision. The video collection server includes a calculation part, a determination part, and a request part. The calculation part calculates, based on information acquired from a camera(s), a first area(s) imaged by the camera(s). The determination part determines a second area(s) as an information provision target(s) based on a location(s) of the first area(s). The request part selects, based on respective locations of the plurality of terminals and a location(s) of the second area(s), a terminal(s) to be requested to perform the information provision from the plurality of terminals and requests the selected terminal(s) to provide video data of the second area(s).
