Surveillance Camera System Audio-Visual Correlation for Incident Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surveillance systems for parking areas are inefficient in quickly grasping details of incidents involving harmed vehicles, as they do not effectively collect and analyze real-time audio and visual data to detect and respond to harmful behaviors such as vehicle break-ins or thefts.
Innovation Solution
A surveillance camera system and method that incorporates cameras and microphones to transmit images and sounds to a server, which detects warning sounds, determines the occurrence position of harming behaviors, and records associated vehicle information, enabling early collection and recording of incident details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video surveillance cameras are used to surveil the entire parking place area, then security coverage is improved, but the ability to quickly detect and respond to harmful behaviors is insufficient
Solution Approach 1:
The surveillance system is segmented into multiple functional components: audio surveillance for detecting harmful behaviors, visual surveillance for capturing images, and a server for analyzing and correlating data. This segmentation allows each component to specialize in specific tasks, improving overall detection speed and reliability.
Solution Approach 2:
The patent merges audio and visual surveillance systems into a unified surveillance camera system that processes both audio and visual data through a server. This combination enables cross-validation of events and faster response by analyzing multiple data streams simultaneously, resolving the contradiction between comprehensive coverage and quick detection.
2Measurement precision
If comprehensive video analysis is performed to detect harmful behaviors, then detection accuracy is improved, but the time required for analysis increases
Solution Approach 1:
The server performs preliminary analysis by continuously monitoring audio streams for warning sounds and pre-identifying potential harmful behaviors before they are fully developed. This preliminary detection allows the system to prepare visual surveillance focus and reduce real-time analysis time while maintaining high accuracy.
Solution Approach 2:
The server acts as an intermediary that processes and correlates audio and visual data, filtering out false alarms and focusing analysis on promising leads. This intermediary processing layer maintains detection accuracy while significantly reducing the time required for comprehensive analysis by pre-sorting and prioritizing data.
3Loss of information
If detailed information collection is performed after an incident occurs, then information completeness is improved, but the responsiveness to the incident is reduced
Solution Approach 1:
The system collects and stores detailed information about vehicles, locations, and surveillance data in advance before incidents occur. When a harmful behavior is detected, the server can immediately retrieve and correlate pre-collected information, providing complete details without delay and eliminating the trade-off between information completeness and response time.
Solution Approach 2:
The server establishes continuous feedback loops that monitor audio and visual data in real-time, immediately triggering information collection and correlation when harmful behaviors are detected. This feedback mechanism ensures both rapid response and complete information gathering by dynamically activating data retrieval based on real-time conditions.

Function Achieved in This Case
This system allows for the early and efficient collection of detailed information about harmed vehicles and incident scenes, improving the speed and accuracy with which surveillance agents can respond to harmful behaviors in parking areas.
Implementation Method 1
The microphone receives a sound of the surveillance area and transmits the output to the server
Data Source
AI summary
A camera transmits a captured image of a surveillance area to a server. A microphone receives a sound of the surveillance area and transmits the sound to the server. The server detects a warning sound starting based on a harming behavior on a vehicle in a surveillance area and arriving from the vehicle using the sound of the surveillance area, determines an occurrence position of the harming behavior based on the detection of the warning sound, acquires a captured image of the occurrence position, determines the vehicle on which the harming behavior is executed using the captured image of the occurrence position, acquires information regarding the vehicle, and records the information regarding the vehicle and the captured image of the occurrence position in association with each other in an accumulator.
