Wireless Signal Receiver for Mobile Device Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Monitoring systems, such as video surveillance, often fail to capture essential information like the identity of intruders during home or business invasions due to limited fields of view or manipulation by intruders, and lack the ability to detect mobile devices without establishing a connection.
Innovation Solution
A wireless signal receiver is activated upon a trigger event, scanning for and processing wireless signals from mobile devices within range to determine their IMEI numbers or other identifiers without establishing a connection, assisting in identifying devices present during unauthorized entry or vandalism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous monitoring of all devices is implemented, then detection accuracy is improved, but energy consumption and system complexity increase
Solution Approach 1:
The system implements periodic scanning of wireless signals only when trigger events occur (such as alarm activation or motion detection), rather than continuous monitoring. The controller scans for device identifiers like IMEI numbers at these specific intervals, reducing energy consumption while maintaining detection accuracy when needed.
Solution Approach 2:
The system pre-configures trigger events and detection parameters in advance. When a trigger event occurs, the system is already prepared to scan for device identifiers immediately, eliminating the need for continuous monitoring while ensuring detection accuracy is maintained at critical moments.
2Loss of information
If video surveillance is used to detect intruders, then visual identification is improved, but field of view limitations and manipulation by intruders reduce detection reliability
Solution Approach 1:
The system uses wireless signal detection as an intermediary method to identify intruders. Instead of relying solely on video surveillance, the system detects device identifiers (IMEI numbers) from mobile devices through wireless signals. This intermediary approach provides reliable identification even when intruders manipulate video systems or move outside the camera's field of view.
Solution Approach 2:
The system combines multiple detection methods: video surveillance for visual identification and wireless signal scanning for device identifier detection. This multi-functional approach ensures that if one method is compromised (e.g., video manipulation), the other method can still provide reliable detection and identification.
3Object-affected harmful factors
If mobile device detection is implemented without establishing connections, then privacy is protected, but detection capability is reduced
Solution Approach 1:
The system extracts only the necessary identification information (device identifiers like IMEI numbers) from wireless signals without establishing full connections with the mobile devices. This extraction approach maintains detection capability by obtaining sufficient identifying information while protecting privacy by avoiding deep device access or continuous connection establishment.

AI summary
Systems, apparatuses, and methods are described for the detection, following a trigger event, of a device that may be sending and/or receiving signals within a space associated with a wireless network. A wireless signal receiver may be activated and may identify the device by detecting transmissions from the device, such as WiFi, Bluetooth, cellular or other wireless transmissions. The wireless signal receiver may extract, without connecting the device to a local network, information from the transmission that may identify the device. The wireless signal receiver may send the information to an alarm monitor and may be placed in a dormant state.
