Surveillance Display Synchronizing Video and Sensor Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surveillance systems require manual searching and evaluation of video and sensor data, making it difficult for security personnel to quickly assess situations in monitored areas, as data from multiple sources needs to be synchronized and filtered for relevant information.
Innovation Solution
A display device that combines video and sensor data in real-time, allowing for interactive selection of time and location, filtering out irrelevant information, and providing an integrated view of events through data combination, event creation, and interpretation modules, enabling efficient monitoring and evaluation of surveillance areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video and sensor data from multiple sources are manually searched and evaluated, then comprehensive monitoring coverage is achieved, but the time required to assess situations and respond to events increases significantly
Solution Approach 1:
The system combines video data from cameras and sensor data from multiple sensors into a unified data structure associated with detected events. This merging allows security personnel to view both video footage and sensor information simultaneously for the same event, providing comprehensive monitoring coverage while reducing the time needed to cross-reference separate data sources manually.
Solution Approach 2:
The system performs preliminary detection and association of video and sensor data before presentation to security personnel. Events are detected, and relevant video and sensor data are pre-associated and organized in advance, so that when security personnel query the system, the comprehensive data is already prepared and ready for immediate review, eliminating manual searching time.
2Loss of information
If data from multiple sensors and video cameras are collected and stored, then complete monitoring information is available, but the complexity of synchronizing and filtering relevant information increases
Solution Approach 1:
The system introduces an event as an intermediary concept that links video data and sensor data. Instead of directly managing the complexity of synchronizing multiple video streams and sensor inputs, the system detects events and associates relevant video and sensor data with each event. This intermediary approach maintains information completeness while simplifying the data structure and reducing synchronization complexity.
Solution Approach 2:
The system segments the large volume of monitoring data into event-specific data sets. Each event contains only the video and sensor data relevant to that specific incident, rather than managing all raw data from all sources. This segmentation reduces the complexity of data filtering and makes it easier to retrieve and analyze relevant information for each event independently.
3Measurement precision
If security personnel review all available video and sensor data, then thorough event evaluation is possible, but the productivity and response efficiency decrease due to information overload
Solution Approach 1:
The system extracts and presents only the video and sensor data that is relevant to each detected event, rather than requiring security personnel to review all available data from all sources. By taking out and displaying only the pertinent information associated with each event, the system maintains thorough event evaluation capability while eliminating information overload and improving response efficiency.

AI summary
Monitoring installations for sensor-based and video monitoring are frequently used in security control centres of public and non-public buildings and spaces. A display apparatus (7) for a monitoring installation (1) of a monitoring area (4) is proposed. The monitoring installation (1) has a plurality of sensors (2) and video cameras (3), wherein the sensors (2) and video cameras (3) each monitor a section of the monitoring area (4), with the sensors (2) providing sensor data (5) and the video cameras (3) providing video data (6). The display apparatus comprises at least one input interface (8a, 8b) for accepting the sensor data (5) and the video data (6) and also a display device (10). The display apparatus comprises a data combination unit (9) and a time selection module (12), the data combination unit (9) being configured to combine the video data (6) and the sensor data (5) from an identical recording time to produce combination data, the time selection module (12) being configured to interactively select a freely selectable time as a selected time (16).
