Solution Overview
Problem
Large security systems with numerous cameras and sensors face difficulties in comprehending and analyzing security events effectively, requiring improved methods for forensic reviews and event correlation.
Innovation Solution
A security system that includes sensors and cameras coupled with processors to detect and correlate security events, automatically generating event records, displaying alerts, and presenting correlated information on a geographic map to facilitate investigation, using a control panel and user interface for real-time monitoring and post-event analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple cameras and sensors are deployed throughout a large facility to detect intruders, then the coverage area and detection capability are improved, but the complexity of analyzing and comprehending security events increases
Solution Approach 1:
The patent segments the large facility into multiple zones or regions, each monitored by specific cameras and sensors. Security events are divided and organized by location, allowing operators to analyze events in manageable segments rather than overwhelming all-at-once data from the entire facility.
Solution Approach 2:
The patent introduces an intermediary processing system that automatically correlates events from multiple cameras and sensors. This intermediary system performs preliminary analysis, filters relevant information, and presents synthesized event data to operators, reducing the complexity of manual analysis while maintaining comprehensive coverage.
2Measurement precision
If recorded video from each camera is reviewed manually to conduct forensic review of events, then the measurement precision of event analysis is improved, but the time required for analysis increases
Solution Approach 1:
The patent performs preliminary actions by automatically processing and pre-analyzing video footage from all cameras as events occur. The system prepares organized event data with key information extracted in advance, so that when forensic review is needed, operators receive pre-processed, relevant information rather than having to manually search through raw footage.
Solution Approach 2:
The patent replaces the mechanical process of manual video review with automated electronic processing systems. Computer algorithms automatically analyze video data, extract relevant events, and organize them for review, substituting human manual analysis with automated systems that operate faster and with consistent precision.
3Speed
If a person at a guard station views television monitors to directly observe intruders, then the real-time detection capability is improved, but the ability to comprehend the true nature of situations in large facilities deteriorates
Solution Approach 1:
The patent merges data from multiple cameras and sensors into unified event presentations that show correlated information from different locations and sources. Instead of isolated monitor views, the system combines related events into comprehensive displays that help operators understand the full situation and context of security incidents.
Solution Approach 2:
The patent adds another dimension to situation comprehension by presenting events in organized displays that show spatial relationships, temporal sequences, and correlations between events. The system transforms two-dimensional monitor views into multi-dimensional event presentations that reveal patterns and connections not visible in individual camera views.
