Surveillance System Using Portable Terminals for Event Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-scale events, the number of security guards is often insufficient to effectively surveil the area, leading to increased costs when trying to augment the security presence.
Innovation Solution
A surveillance system that utilizes portable terminals carried by event attendees to capture images and transmit participation consent, allowing non-security personnel to contribute to surveillance efforts, thereby enhancing coverage without the need for additional security personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of security guards is increased to improve surveillance coverage, then surveillance effectiveness is improved, but cost increases
Solution Approach 1:
The patent enables portable terminals to serve dual purposes: their original functions plus surveillance participation. By making the surveillance system universal enough to accept any portable terminal (smartphones, tablets) from event attendees, the system eliminates the need for dedicated surveillance hardware and reduces reliance on additional security personnel, thereby lowering costs while maintaining coverage.
Solution Approach 2:
The patent creates virtual copies of security surveillance functions by leveraging the image capturing units already present in attendees' portable terminals. Instead of requiring physical security guards to manually monitor areas, the system captures surveillance data through the copied imaging capability of civilian devices, reducing the need for additional human resources and associated costs.
2Area of stationary object
If the number of security guards is increased to improve area coverage, then surveillance coverage is improved, but device complexity increases
Solution Approach 1:
The system achieves wide area coverage without increasing operational complexity by making the surveillance platform universal. Any portable terminal carried by event attendees can be recruited for surveillance, eliminating the need for complex dedicated surveillance infrastructure. The system leverages existing simple devices (smartphones) that attendees already possess, keeping the overall system simple while expanding coverage area.
Solution Approach 2:
The patent distributes surveillance functionality through copies of the basic imaging function found in numerous portable terminals across the event area. Instead of deploying a single complex centralized surveillance system, the system uses many simple, replicated imaging units held by attendees, simplifying the overall system architecture while achieving comprehensive area coverage.

AI summary
A surveillance system (1) includes an area information acquisition unit (101), a request information provision unit (102), and a participation consent reception unit (103). The area information acquisition unit (101) acquires information of a surveillance-desired area. The request information provision unit (102) provides participation request information for surveillance that is conducted by using an image capturing unit of a portable terminal in the surveillance-desired area. The participation consent reception unit (103) receives participation consent as a response to the participation request information, from the portable terminal.
