Surveillance System Using Electromagnetic Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surveillance systems struggle to differentiate between authorized and unauthorized individuals, leading to frequent false alarms and requiring manual intervention to avoid triggering alarms when people are present in the monitored area.
Innovation Solution
A surveillance system comprising sensors and a remote control device that uses electromagnetic waves to automatically authenticate authorized individuals by comparing authorization data, preventing false alarms and allowing continuous monitoring without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the surveillance system is activated to monitor the protected area, then security monitoring capability is improved, but false alarms increase when authorized persons are present
Solution Approach 1:
The patent replaces traditional mechanical sensor-based detection with electromagnetic wave-based recognition technology. The system uses electromagnetic waves to detect and recognize authorized persons, substituting the mechanical sensor activation approach with a more intelligent electromagnetic field-based identification system that can distinguish between authorized and unauthorized individuals.
Solution Approach 2:
The patent introduces an intermediary recognition system that acts as a mediator between the surveillance system and detected persons. This intermediary layer analyzes electromagnetic wave responses to determine authorization status, preventing direct false alarm triggering and enabling the system to maintain activation without being disturbed by authorized persons.
2Object-generated harmful factors
If the surveillance system requires manual intervention to avoid false alarms, then false alarm reduction is achieved, but system complexity and ease of operation worsen
Solution Approach 1:
The patent implements self-service functionality where the surveillance system automatically recognizes and identifies authorized persons without requiring manual intervention. The system independently processes electromagnetic wave data, determines authorization status, and makes decisions about alarm triggering, eliminating the need for human operators to manually adjust system behavior.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously monitors electromagnetic wave responses from detected persons, compares them against stored authorization data, and adjusts its behavior accordingly. This closed-loop feedback system automatically learns and adapts to distinguish authorized from unauthorized individuals, reducing false alarms without manual input.
3Device complexity
If traditional sensors are used for detection, then device simplicity is maintained, but discrimination capability between authorized and unauthorized persons deteriorates
Solution Approach 1:
The patent changes the fundamental detection parameter from mechanical sensor activation to electromagnetic wave characteristics. By measuring and analyzing multiple parameters of electromagnetic wave interactions (frequency, phase, amplitude, response time), the system achieves high discrimination capability between authorized and unauthorized persons while maintaining practical system complexity through integrated processing.
