Virtual Card Reader for Flexible Access Control Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems require card readers to determine permission and non-permission of entry into specific zones, limiting flexibility in setting monitoring areas and increasing administrative burdens when card readers are not installed.
Innovation Solution
A monitoring area setting device and method that allows administrators to generate access control rules including virtual card reader information, enabling flexible setting of monitoring areas and supporting efficient monitoring operations by integrating camera and card reader information, even in areas without physical card readers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If card readers are installed in all zones to determine entry permission, then entry permission determination accuracy is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent creates virtual card reader information that copies the functional capabilities of physical card readers. The virtual card reader information includes zone identification and permission determination logic, allowing the system to determine entry permission for zones without physical card readers by using camera-based face recognition as a substitute for card reading operations.
Solution Approach 2:
The patent replaces the mechanical card reading system with an optical recognition system. Instead of using card readers to read physical cards, the system uses cameras to capture face images and processes these images to determine entry permission, thereby eliminating the need for physical card readers in monitored zones.
2Reliability
If physical card readers are installed in all monitored areas, then access control reliability is improved, but adaptability to different areas decreases
Solution Approach 1:
The patent creates a universal access control system where virtual card reader information can be applied to any zone without requiring physical card reader installation. The system can switch between camera-based monitoring and card reader-based control depending on the zone configuration, making the access control system adaptable to both zones with and without physical card readers while maintaining reliable permission determination.
3Adaptability or versatility
If virtual card reader information is generated for zones without physical card readers, then monitoring area flexibility is improved, but device complexity increases
Solution Approach 1:
The patent introduces virtual card reader information as an intermediary element that bridges the gap between zones without physical card readers and the access control system. This virtual information structure includes zone identification and permission data, allowing the system to treat virtual and physical card reader zones uniformly while maintaining system manageability through centralized virtual card reader information storage and processing.
Data Source
AI summary
A monitoring area setting device includes a storage unit storing information of one area and card reader information of a card reader corresponding to the area, an input unit receiving an administrator operation, and a processor generating, based on the administrator operation, an access control rule including information of a monitoring area to be monitored by a camera in the area and person information of a person that allows access to the monitoring area. When the card reader information corresponding to the monitoring area is input, the processor generates the access control rule further including the card reader information. When the card reader information corresponding to the monitoring area is not input, card reader information of a virtual reader designated by the administrator operation for access to the monitoring area is generated, and the access control rule further including generated card reader information of the virtual reader is generated.
