Body-Worn Camera Video Tagging With Turntable Category Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Police officers spend significant time tagging category names for recorded videos after duty, which is time-consuming due to heavy workloads.
Innovation Solution
A body-worn camera with a central processing unit, video recording module, turntable, and main button that automatically saves the relationship between category names and recorded videos upon user input, eliminating the need for post-recording tagging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If police officers manually tag category names for recorded videos at the police station after duty, then video categorization is completed, but significant time is consumed due to heavy workloads
Solution Approach 1:
The system performs video categorization at the moment of recording completion, before the officer returns to the station. The turntable interface allows immediate category selection, and the processor automatically tags the video with the selected category, eliminating the need for post-duty manual tagging and significantly reducing time loss.
Solution Approach 2:
The body-worn camera system performs automatic video tagging through its built-in turntable interface and processing capabilities. The officer simply rotates the turntable to select a category, and the system automatically completes the tagging operation without requiring external server resources or additional manual effort at the station, making the device self-sufficient for categorization tasks.
2Ease of operation
If police officers return to the police station to connect body-worn cameras to servers for video tagging, then comprehensive video categorization is achieved, but the process becomes time-consuming and reduces on-duty efficiency
Solution Approach 1:
The system completes the entire video tagging operation at the scene before the officer returns to the station. The turntable provides an intuitive interface for category selection, and the onboard processor immediately processes and saves the category information, making the tagging process convenient and eliminating the need to wait at the police station.
Solution Approach 2:
The video tagging function is extracted from the police station server environment and integrated directly into the body-worn camera. This extraction allows the tagging operation to be performed independently at the scene, removing the dependency on station servers and the associated time loss for connection and processing.
3Productivity
If the body-worn camera includes automatic tagging functionality with turntable and main button, then time efficiency is improved, but device complexity increases
Solution Approach 1:
The turntable is designed to serve multiple functions: it displays video information, allows category selection through rotation, and confirms selections when pressed. The main button similarly serves both as a recording control and a category confirmation button. This multi-functionality reduces the need for separate dedicated components, managing device complexity while maintaining enhanced productivity.
Solution Approach 2:
The display function and input control function are merged into the turntable component. The turntable both presents category options to the officer and receives the officer's selection through rotation and pressing actions. This merging of functions into a single component avoids adding separate display and input devices, thereby limiting the increase in device complexity.
Data Source
AI summary
A body-worn camera and an operation method thereof are provided, and the body-worn camera a central processing unit, a video recording module, a turntable, and a main button. The video recording module is electrically connected to the central processing unit. The turntable is electrically connected to the central processing unit. The main button is electrically connected to the central processing unit. After the video recording module completes recording a video, when the central processing unit receives a category mode signal from the turntable and receives a category name confirmation signal from the main button, the central processing unit executes a video tagging program, and the video tagging program saves a corresponding relationship between a category name and the video.
