Wireless Device Alert System for Intruder Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security systems fail to provide satisfactory evidence for identifying intruders, as they often cannot distinguish between known and unknown wireless devices, especially when intruders wear disguises or are in close proximity to known devices, leading to unreliable visual identification.
Innovation Solution
Implementing a method where access devices receive and analyze communication signals from wireless devices, comparing identification information to a list of known devices, and generating an alert when unknown devices are detected, along with determining their location within the premises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual security systems are used to detect intruders, then intruder detection capability is provided, but identification reliability deteriorates due to disguises and poor video quality
Solution Approach 1:
The patent replaces visual/mechanical detection systems with wireless signal-based detection. Instead of relying on cameras and visual identification, the system uses wireless communication signals to detect and identify intruders, thereby overcoming the limitations of visual systems in distinguishing between known and unknown devices.
Solution Approach 2:
The patent introduces wireless communication signals as an intermediary medium for detection. Rather than directly observing intruders visually, the system uses wireless signals as a mediator to detect the presence and identity of devices, providing more reliable identification that is not affected by disguises or video quality.
2Reliability
If security systems monitor all wireless devices, then detection coverage is improved, but false alarms increase due to proximity to known devices
Solution Approach 1:
The patent applies local quality by analyzing the specific characteristics and location of each wireless signal source. Instead of treating all wireless devices uniformly, the system examines individual device identifiers and their spatial relationships with known devices to make accurate determinations about intruder presence.
Solution Approach 2:
The patent segments the detection process into distinct steps: receiving wireless communications, identifying device information, comparing with known devices, and determining intruder status. This segmentation allows the system to handle complex identification tasks systematically, reducing false alarms while maintaining comprehensive coverage.

AI summary
Methods, systems, and computer readable media can be operable to generate an alert in response to a detection of an unexpected wireless device within a premises. An access device may receive a communication from a wireless device and may retrieve identification information associated with the wireless device from the communication. The access device may compare the retrieved identification information to identification information associated with one or more known devices, and if the retrieved identification information does not match the identification information associated with any of the known devices, the access device may identify the wireless device as an unexpected wireless device. The access device may output an alert providing a notification that an unexpected wireless device has been detected within an associated premises.
