Surveillance Video Carousel Interface for Event Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surveillance camera video display methods become increasingly difficult to manage as the number of cameras grows, making it challenging for security guards to monitor multiple views effectively.
Innovation Solution
A method and system for analyzing and displaying surveillance video by capturing and analyzing frames, generating activity of interest video clips, and displaying them in a carousel on a display device, which can rotate and enlarge thumbnails to prioritize important events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the grid method is used to display multiple surveillance camera views simultaneously, then all camera views can be monitored at once, but the individual grids for each surveillance camera need to shrink and become increasingly difficult to monitor as more cameras are added
Solution Approach 1:
The patent segments the surveillance video feed into multiple discrete carousel components, each representing a specific camera or area of interest. Instead of displaying all cameras in a single grid, the system divides them into separate rotatable carousels that can be independently navigated, allowing security guards to focus on one segment at a time while still having access to all camera views.
Solution Approach 2:
The patent introduces dynamic interaction by making the carousels rotatable and allowing users to navigate through camera views on demand. This dynamic navigation replaces the static grid layout, enabling security guards to actively select and focus on specific areas of interest by rotating the carousel to bring desired camera views into the center position.
2Quantity of substance
If the grid method is used to display multiple surveillance camera views, then all views are visible, but there are too many surveillance cameras for one security guard to monitor effectively
Solution Approach 1:
The patent implements partial action by allowing security guards to view only a subset of camera feeds at any given moment through the rotatable carousel mechanism. Instead of requiring all cameras to be visible simultaneously, the system enables guards to cycle through and focus on relevant cameras, performing the monitoring task in stages rather than attempting to process all views at once.
Solution Approach 2:
The carousel interface acts as an intermediary between the large number of available camera feeds and the security guard's limited attention capacity. It provides a structured mechanism for navigating and selecting which cameras to monitor, mediating the interaction between the overwhelming quantity of video inputs and the human operator's ability to process them effectively.
3Loss of information
If the carousel rotates thumbnails to prioritize important events, then relevant events are highlighted, but the system must analyze and select activities of interest from multiple video frames
Solution Approach 1:
The patent extracts and isolates only the most relevant portions of video content by using activity detection algorithms to identify and pull out segments containing activities of interest. Instead of displaying all video frames equally, the system extracts specific clips that contain meaningful events, removing irrelevant content from the display and focusing attention on what matters most.
Solution Approach 2:
The system performs preliminary analysis of video frames to pre-identify activities of interest before displaying them in the carousel. By analyzing and categorizing video content in advance, the system can prioritize and organize thumbnails based on their relevance, ensuring that the most important events are positioned prominently in the carousel rotation without requiring real-time analysis during display.

AI summary
A method for analyzing and displaying surveillance video including: capturing, using a first video camera, a first plurality of video frames of a first area at a first time; analyzing the first plurality of video frames or linking to one or more alarms received; determining a first activity of interest within one or more first video frames of the first plurality of video frames; generating a first activity of interest video clip from the one or more first video frames; and displaying the first activity of interest video clip within a first carousel on a display device, wherein the first activity of interest video clip is configured to rotate around a first axis within the first carousel on the display device.
