Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video collection and storage systems face challenges in efficiently transmitting and processing video data from multiple cameras, particularly in high-definition formats, leading to delays and inefficiencies in law enforcement and other large-scale applications.
Innovation Solution
A video collection system that utilizes a mobile broadband network to send metadata, receive triggers, and manage video data transmission and processing, allowing for remote control and management of video cameras, including the ability to trigger recordings and tag video data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data is transmitted using standard Wi-Fi connection, then small files can be transferred adequately, but large high-definition video files and multiple camera systems result in slow and unreliable transfer
Solution Approach 1:
The patent replaces the mechanical Wi-Fi file transfer system with an automated cellular network-based video collection system. The video camera uses a cellular modem to automatically transmit video data and metadata to a remote video collection manager, eliminating the manual Wi-Fi transfer process and improving both speed and reliability for large-scale deployments.
Solution Approach 2:
The patent introduces a remote video collection manager as an intermediary between video cameras and the backend system. This manager coordinates video collection, receives automated transmissions via cellular network, and manages data routing, thereby improving transfer reliability and speed across multiple camera systems.
2Loss of time
If video data is transmitted in real-time over cellular network, then transfer time is reduced, but bandwidth consumption and processing load increase
Solution Approach 1:
The patent segments video data transmission by separating metadata (transmitted frequently and quickly) from actual video content (transmitted selectively). The video camera sends metadata messages containing video data information to the remote video collection manager, which then requests specific video segments as needed, reducing unnecessary bandwidth consumption while maintaining fast transfer capability.
Solution Approach 2:
The patent implements preliminary action by having the video camera send metadata information about recorded video data before the actual video transmission. This allows the remote video collection manager to pre-coordinate transmission requests, plan bandwidth usage, and retrieve only necessary video segments, optimizing bandwidth consumption while maintaining rapid transfer capability.
3Productivity
If an administrator can remotely instruct and control video recording, then transfer time and processing time are reduced, but system complexity increases
Solution Approach 1:
The remote video collection manager serves multiple functions: it receives metadata from video cameras, processes trigger messages, coordinates video data requests, manages bandwidth allocation, and controls multiple cameras simultaneously. This multi-functionality consolidates system complexity into a single centralized manager while improving overall video processing efficiency.
4Reliability
If physical memory card transfer is used, then data loss risk is reduced compared to wireless transfer, but it requires manual intervention and is prone to human error
Solution Approach 1:
The video camera system performs self-service by automatically transmitting video data and metadata through the cellular network to the remote video collection manager. This eliminates the need for manual memory card removal and physical transfer, reducing human error while maintaining data integrity through automated, coordinated transmission protocols.
Data Source
AI summary
A video collection system collects and sends metadata related to video data such that recording may be triggered and tagged. The video collection system utilizes a mobile broadband network (such as a cellular network) to send metadata, receive triggers, and perform other functions while the video collection system is in the field. The video collection system broadly comprises a plurality of video cameras and a video collection manager. The video cameras each include a mobile broadband modem or other wireless communication element for sending metadata messages. In some embodiments the mobile broadband modem may also send still images, audio data, and video data.
