Surveillance Motion Detection Perimeter Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surveillance systems face challenges in prioritizing and effectively alerting users to important motion detection across multiple cameras, leading to resource wastage and missed important information due to inadequate alarm generation and interpretation.
Innovation Solution
A surveillance apparatus and method that uses perimeter data to create visual representations of motion, allowing users to identify and prioritize camera feeds with detected motion, including shape recognition and semi-transparent alerts that overlay video feeds without obscuring them, enabling efficient switching between cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video data from all cameras is presented to the viewer, then the viewer can see all events, but the viewer becomes overwhelmed and cannot identify which cameras require attention
Solution Approach 1:
The patent extracts only the essential information (motion detection alerts with perimeter outlines) from the full video data and presents it to the viewer. This allows the viewer to identify important events without being overwhelmed by all video feeds, resolving the contradiction between complete information availability and manageable presentation complexity
Solution Approach 2:
The patent segments the surveillance information by creating individual motion detection alerts for each camera that detects motion. Each alert is displayed as a separate overlay on the video feed, allowing the viewer to process information camera-by-camera rather than being presented with all data simultaneously, thus reducing overwhelming complexity while maintaining comprehensive monitoring
2Device complexity
If only one camera video is presented to the viewer, then the data presentation is simplified, but important events in other cameras may be missed
Solution Approach 1:
The system provides feedback to the viewer by displaying motion detection alerts with perimeter outlines directly on the video feeds. When motion is detected in any camera, an alert is immediately presented to the viewer, enabling them to identify and switch to the relevant camera without missing important events, thus maintaining simplicity while preventing information loss
Solution Approach 2:
The system performs preliminary analysis of video data to detect motion before the viewer needs to view the footage. By pre-identifying which cameras have detected motion and preparing alerts in advance, the system ensures that important events are not missed while keeping the interface simple and focused on relevant information
3Loss of information
If detailed information is provided in alerts, then the viewer can assess events accurately, but the resources required to generate and process alerts increase
Solution Approach 1:
The patent extracts only the most essential information for alert generation - the perimeter outline of the moving object and its location. This minimal yet sufficient information allows the viewer to assess events accurately without requiring the system to process and generate comprehensive detailed information, thus reducing computational resources while maintaining effective event assessment
Solution Approach 2:
The system applies partial action by providing just enough information in the alerts (perimeter outlines and location) to enable effective event assessment, rather than providing complete exhaustive details. This partial information approach reduces processing resources while still allowing the viewer to determine whether further investigation of specific camera feeds is necessary
4Measurement precision
If the viewer must view video to understand alarm context, then accurate assessment is possible, but time and resources are wasted viewing potentially irrelevant information
Solution Approach 1:
The system performs preliminary analysis by detecting motion and generating alerts with perimeter outlines before the viewer needs to make an assessment. This pre-processing allows the viewer to quickly understand alarm context from the visual perimeter indicators without having to immediately view the full video, reducing time loss while maintaining assessment accuracy
Solution Approach 2:
Instead of requiring the viewer to watch video to understand what triggered an alarm, the patent inverts the approach by providing visual perimeter indicators that immediately reveal the nature and location of detected motion. This reversal allows accurate event assessment without time-consuming video viewing, eliminating the need to watch footage to understand alarm context
