Wireless Intruder Identification via Portable Device Scanning
Solution Overview
Problem
Conventional security systems often fail to effectively identify intruders in a timely manner, especially when the secured area is remote from police facilities or when police are unavailable, as they rely solely on sensor activation and local alarms without the capability to determine the perpetrator's identity.
Innovation Solution
Incorporating a wireless device detector within the security system that scans for and identifies portable devices carried by individuals within the secured area, using communication protocols to establish connections and obtain identifiers, which are then sent to a central monitoring station to alert authorities, even if the device is in silent mode or outside the area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional sensors and local alarms are used, then the system can detect intruders and alert locally, but the system cannot identify the intruder's identity or enable remote tracking
Solution Approach 1:
The security system is enhanced with a wireless device detector that performs multiple functions: detecting intruders via traditional sensors, identifying intruders through portable device detection, and enabling remote tracking. This multi-functional approach resolves the contradiction by adding identification capability without requiring entirely separate systems.
Solution Approach 2:
A portable device (cell phone or similar wireless device) carried by the intruder serves as an intermediary that enables identification and tracking. The device detector intercepts signals from this intermediary device to obtain identification information, thereby solving the identification problem without direct contact with the intruder.
2Loss of time
If police are dispatched immediately after sensor activation, then response time is reduced, but police may still not arrive in time due to distance or unavailability
Solution Approach 1:
The system performs preliminary identification of the intruder through device detection before police arrival. By obtaining the intruder's device identifier in advance, the system prepares critical information that will accelerate police response and increase the likelihood of successful intervention when authorities do arrive.
Solution Approach 2:
The system provides feedback to authorities by transmitting intruder identification information to a central monitoring station, which then relays this information to police. This feedback loop ensures that police receive not just an alarm notification but also specific identification data about the intruder.
3Area of stationary object
If the system monitors only within the secured area, then detection coverage is focused, but the system cannot track intruders who flee the scene
Solution Approach 1:
The system replaces physical surveillance or pursuit mechanisms with electronic tracking through wireless device detection. By using the intruder's portable device as a tracking target, the system can monitor the intruder's location electronically beyond the physical boundaries of the secured area, eliminating the need for physical pursuit.

AI summary
A method and apparatus are provided for identifying wireless devices within a security system. The method includes the steps of providing a security system monitoring a secured area for an intruder, the security system detecting an intrusion of the secured area, the security system detecting a mobile device within the secured area, the security system retrieving an identifier of the intruder from the mobile device and the security device saving the identifier along with a record of the intrusion.
