Solution Overview
Problem
Existing surveillance systems fail to provide reliable real-time video streaming from remote and mobile locations due to the lack of effective communication methods, as they often lack the necessary infrastructure for transmitting video streams over various communication paths.
Innovation Solution
A tactical information transport surveillance system that includes a portable housing with an integrated antenna, battery, printed circuit board, video converter, encoder, router, and analytics system, capable of converting video streams into a reduced bitrate digital signal and transmitting them over multiple communication paths such as cell towers, satellites, and MANET radios, allowing real-time livestreaming to the internet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video streams are transmitted from remote locations using existing surveillance systems, then real-time surveillance capability is improved, but transmission reliability deteriorates due to lack of communication infrastructure
Solution Approach 1:
The system dynamically selects and switches between multiple communication paths (cellular, satellite, mesh network, radio) based on availability and conditions. The router continuously monitors communication path status and automatically routes video streams through the most reliable available path, enabling reliable transmission in remote areas with limited infrastructure.
Solution Approach 2:
The encoder dynamically adjusts video stream parameters including bitrate, resolution, and frame rate based on communication path conditions and available bandwidth. This allows the system to maintain reliable transmission by adapting video quality to match the capabilities of the current communication path, ensuring continuous operation even in remote locations.
2Adaptability or versatility
If video streams are transmitted in real-time from mobile locations, then surveillance coverage is improved, but system portability deteriorates due to infrastructure requirements
Solution Approach 1:
The system integrates multiple previously separate functions into a single portable unit: camera, encoder, router, and communication interfaces are combined in one housing. This consolidation enables the entire surveillance system to be transported to remote locations while maintaining all necessary functions for real-time video transmission through multiple communication paths.
Solution Approach 2:
The surveillance system is designed with universal communication capabilities that can operate through multiple different communication paths (cellular, satellite, mesh network, radio). This multi-functionality allows a single portable system to adapt to various remote locations regardless of which communication infrastructure is available, eliminating the need for location-specific installations.
3Productivity
If video streams are compressed to reduce bitrate for remote transmission, then transmission efficiency is improved, but video quality deteriorates
Solution Approach 1:
The encoder dynamically adjusts compression parameters including bitrate, resolution, and frame rate based on real-time communication path conditions and available bandwidth. This dynamic adaptation allows the system to maximize transmission efficiency by compressing video appropriately for each communication scenario while maintaining the highest possible quality within those constraints.
Solution Approach 2:
The system changes video stream parameters such as bitrate, resolution, and encoding format based on the selected communication path and available bandwidth. By adjusting these parameters dynamically, the system achieves efficient transmission over bandwidth-constrained remote connections while preserving adequate video quality for surveillance purposes.
