Portable Terminal Surveillance Network Using Attendee Consent
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 quality is improved, but cost increases
Solution Approach 1:
The invention enables portable terminals to serve dual purposes: personal use and surveillance. By allowing event attendees to use their own devices for surveillance while wearing body-worn cameras, the system makes the surveillance function universal rather than exclusive to security personnel, thereby improving coverage without proportionally increasing cost.
Solution Approach 2:
Event attendees perform surveillance functions themselves using their personal portable terminals and body-worn cameras. This self-service approach distributes the surveillance task across multiple individuals rather than concentrating it on security guards, enabling better coverage with the same or reduced resource investment.
2Reliability
If body-worn cameras are provided to all security guards to improve surveillance quality, then surveillance coverage is improved, but device cost increases
Solution Approach 1:
Instead of providing expensive body-worn cameras to all security personnel, the system uses copies of surveillance functionality already present in attendees' portable terminals. The body-worn cameras capture images that are transmitted to these existing devices, effectively copying the surveillance function without requiring additional specialized hardware for each participant.
Solution Approach 2:
Portable terminals that would normally be used solely for personal communication are made multi-functional by enabling them to serve as surveillance devices. This universality eliminates the need for separate dedicated surveillance hardware for each participant, reducing overall device cost while maintaining comprehensive 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.
