Solution Overview
Problem
Traditional home security systems face challenges in detecting intruders and identifying individuals within a geographical area due to connectivity issues and limitations of sensors, which can lead to missed intrusions and difficulty in determining the identity of potential intruders.
Innovation Solution
The use of RF detecting devices capable of detecting RF emissions from devices within a predetermined area, determining anomalies based on established thresholds, and communicating indications of these anomalies to authorized parties, allowing for improved security monitoring without disrupting privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sensors and connectivity systems are used for home security, then the system structure is simple, but the detection reliability is low due to missed intrusions and inability to identify intruders
Solution Approach 1:
The patent replaces traditional mechanical sensors (motion detectors, door sensors) with RF emission detection technology. By monitoring RF emissions from devices like smartphones and RFID tags, the system achieves more reliable intruder detection and identification without relying on fragile mechanical sensing systems.
Solution Approach 2:
The patent introduces RF emissions as an intermediary carrier for detection. Instead of directly detecting physical presence with sensors, the system detects RF signals emitted by intruders' devices, which serve as intermediaries to convey presence and identity information.
2Measurement precision
If RF detecting devices are deployed to monitor emissions, then the detection precision is improved, but the privacy concerns increase due to potential surveillance
Solution Approach 1:
The patent extracts only the RF emission signals from the intruder's devices for analysis, without extracting or storing personal data, content of communications, or other sensitive information. This selective extraction maintains detection precision while minimizing privacy intrusion.
Solution Approach 2:
The patent converts the potentially harmful act of surveillance into a beneficial security function by using RF emissions that devices already emit for normal operation. The system repurposes these necessary emissions for security detection without requiring additional intrusive monitoring.
3Reliability
If multiple detection methods are combined to improve security, then the reliability is enhanced, but the device complexity increases
Solution Approach 1:
The patent merges RF emission detection with traditional security systems by integrating the RF detection module into existing security architectures. This combination enhances security reliability by adding a new detection dimension while leveraging existing infrastructure.
Solution Approach 2:
The RF detection system serves multiple functions: detecting intruder presence, identifying intruders through device fingerprinting, and potentially tracking movement patterns. This multi-functionality achieves enhanced security reliability without proportionally increasing complexity.

AI summary
Systems, methods, and computer-readable media herein provide for detecting anomalies in RF emissions. RF emissions may be detected within a predetermined geographical area, for example by an RF detecting device. It is determined that at least a portion of the RF emissions trigger a predetermined threshold, such as a set of rules. Based on the RF emissions triggering a predetermined threshold, an anomaly is identified in the RF emissions. An indication of the anomaly is communicated to, for example, a third party device.
