Remote Video Retrieval via On-Demand Segments Over Metered Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video surveillance systems face challenges in centralized management and secure global access due to their on-premise and vendor-specific nature, with IP cameras requiring costly and limited bandwidth for remote access, especially in remote locations with metered connections.
Innovation Solution
A system that records video locally using onsite storage and allows users to access specific video segments on demand, utilizing a cloud-based server to manage streaming connections based on user demand, reducing data usage and costs, and supporting configurable bit rates for various connection speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video is continuously streamed over cellular or satellite connections for remote access, then global accessibility is improved, but data usage costs and bandwidth consumption increase significantly
Solution Approach 1:
The system implements periodic action by downloading video data in scheduled intervals rather than continuous streaming. The mobile device periodically connects to the remote location to download video segments from the storage device, reducing overall data transmission time and cost while maintaining accessibility.
Solution Approach 2:
The system applies preliminary action by downloading and caching video data in advance before it is needed for viewing. Video segments are pre-downloaded to the mobile device or intermediate server, so when the user wants to access the video, it is already available locally without requiring expensive real-time cellular or satellite streaming.
2Speed
If video data is downloaded and stored locally on mobile devices, then access speed is improved, but device storage requirements and data management complexity increase
Solution Approach 1:
The system introduces an intermediary server that acts as a middle layer between the remote storage device and mobile devices. The server handles video data storage, management, and distribution, offloading the complexity from mobile devices while enabling fast local access. The server maintains video segments and manages downloads to multiple devices without requiring each device to handle complex storage management.
3Reliability
If on-premise DVR/NVR systems are used for video surveillance, then video quality and reliability are maintained, but remote accessibility and centralized management are limited
Solution Approach 1:
The system implements universality by creating a multi-functional architecture that combines local storage capabilities with remote access functionality. The storage device at the remote location serves multiple purposes: local video recording, periodic data transmission, and cloud-like storage accessible from multiple devices. This eliminates the vendor-specific limitations of conventional DVR/NVR systems while maintaining video quality through local storage.

AI summary
Methods and systems provided. A system may include an application program. The application program may be configured enable data captured by a remote device at a remote location to be viewable via an end-user device without transmitting the data to the end-user device. Further, after enabling the data to be viewable and in response to an input, the application program may be configured to cause a previously captured video associated with the data to be sent from the remote device via a metered connection.
