Surveillance System Dynamic Guard Relocation for Coverage Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-scale events, the number of security guards is often insufficient relative to the number of attendees, leading to poorly-surveilled areas.
Innovation Solution
A surveillance system that includes an area information acquisition unit, a position information acquisition unit, a candidate determination unit, and a notification output unit to identify and relocate portable terminals to areas requiring enhanced surveillance based on position information and congestion analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of security guards is increased to improve surveillance coverage, then the surveillance coverage is improved, but the cost and complexity of the surveillance system increases
Solution Approach 1:
The surveillance system performs self-management by automatically monitoring guard positions, identifying coverage gaps, and notifying relevant personnel. The system autonomously determines when and where additional surveillance is needed without requiring manual coordination or complex centralized control, thus improving coverage while maintaining simple system architecture.
Solution Approach 2:
The system continuously monitors the positions of portable terminals and surveillance personnel, provides real-time feedback about coverage status to both the control device and individual guards, and enables dynamic adjustment of guard deployment based on actual surveillance needs, resolving the contradiction between improved coverage and system complexity.
2Reliability
If security guards are deployed to cover all areas, then surveillance coverage is improved, but the response time to dynamic situations deteriorates
Solution Approach 1:
The surveillance system transitions from static guard deployment to dynamic positioning based on real-time conditions. Guards are notified to move to specific areas only when coverage gaps are detected, allowing the system to maintain comprehensive coverage while enabling rapid response to changing surveillance needs without requiring guards to be constantly redeployed.
3Productivity
If manual coordination of security guards is used to optimize placement, then surveillance efficiency is improved, but the operational complexity and time consumption increase
Solution Approach 1:
The system automatically performs the coordination function that would otherwise require manual intervention. The control device autonomously monitors surveillance coverage, identifies gaps, determines optimal guard positions, and sends notifications to relevant personnel, eliminating the need for manual coordination while maintaining high surveillance efficiency and simple operation.

AI summary
A surveillance system (1) includes an area information acquisition unit (101), a position information acquisition unit (102), a candidate determination unit (103), and a notification unit (104). The area information acquisition unit (101) acquires information of a surveillance-desired area. The position information acquisition unit (102) acquires pieces of position information of a plurality of portable terminals (20), each portable terminal performing surveillance using an image capturing unit. The candidate determination unit (103) determines a candidate portable terminal (20) to be moved to the surveillance-desired area from among the plurality of portable terminals (20) based on the acquired pieces of position information of the plurality of portable terminals (20). The notification unit (104) outputs a notification to the candidate portable terminal requesting to move to the surveillance-desired area.
