Location-Based Tracking Filter Circuit for Unauthorized Person Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video monitoring systems face challenges in accurately distinguishing between authorized and unauthorized individuals, particularly in dynamic environments, leading to false alarms and inefficient manual monitoring.
Innovation Solution
A system comprising cameras and a filter circuit that tracks authorized users' locations using location-based information, comparing detected individuals' locations to determine authorized status and enabling or disabling alarm systems accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video monitoring systems detect all individuals in dynamic environments, then security coverage is improved, but false alarms increase due to authorized personnel being detected as unauthorized
Solution Approach 1:
The patent introduces location-based information as an intermediary element to distinguish between authorized and unauthorized individuals. By comparing detected individual locations with tracked authorized user locations, the system mediates the detection process to prevent false alarms while maintaining security coverage.
Solution Approach 2:
The system changes the parameter of individual identification from simple presence detection to location-based verification. By adding the location parameter and comparing it against tracked authorized locations, the system transforms the detection criteria to eliminate false alarms caused by authorized personnel.
2Measurement precision
If manual monitoring of video is implemented, then detection accuracy is improved, but operational efficiency deteriorates due to the challenging and unreliable nature of manual monitoring
Solution Approach 1:
The patent replaces manual video monitoring with an automated location-based verification system. The mechanical process of manual review is substituted with automated comparison of location data, maintaining detection accuracy while dramatically improving operational efficiency and reliability.
Solution Approach 2:
The system enables self-service monitoring by automatically comparing detected individual locations with tracked authorized user locations. The monitoring system serves itself by autonomously verifying authorization status without requiring manual intervention, thereby improving both accuracy and efficiency.
3Object-generated harmful factors
If location-based tracking is implemented for authorized users, then false alarm reduction is improved, but system complexity increases due to additional tracking infrastructure
Solution Approach 1:
The patent applies location-based tracking technology that serves multiple functions: it tracks authorized users for security verification purposes while also enabling operational efficiency improvements. This multi-functionality justifies the added complexity by providing benefits beyond false alarm reduction.
Data Source
AI summary
Aspects of the present disclosure are directed to tracking authorized individuals, and identifying the presence of unauthorized individuals. As may be consistent with one more embodiments, respective cameras capture images of regions of a common premises, and a filter circuit detects the presence of individuals in the images, and filters the detected presence as follows. The location of one or more authorized users are tracked relative to the premises via location-based information indicative of each authorized user's location. Each detected individual's location is identified and compared to the tracked location of the at least one authorized user. The detected individual is identified as being an unauthorized individual in response to the comparison indicating that the identified location is not common to the tracked location.
