Front-end Device Collaboration Method for Video Surveillance Delay Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In security and protection systems, the collaboration between multiple internet protocol cameras (IPCs) in video surveillance systems often results in delays due to the need for control instructions to be forwarded through a video management system (VMS), which is problematic in real-time scenarios like airport surveillance.
Innovation Solution
A front-end device collaboration method where a first front-end device directly sends a collaboration instruction to a second front-end device upon detecting a preset trigger event, eliminating the need for the instruction to be forwarded through a security protection platform, thereby reducing operational delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If control instructions are forwarded through the VMS for IPC collaboration, then system management and control are simplified, but collaboration delay increases
Solution Approach 1:
The patent introduces a collaboration instruction forwarding mechanism where the VMS acts as an intermediary that receives collaboration instructions from one IPC and forwards them to target IPCs. This mediator approach allows IPCs to maintain simple individual structures while the VMS handles the complexity of collaboration coordination, resolving the contradiction by centralizing management functions in the VMS while enabling direct IPC-to-IPC instruction forwarding for real-time collaboration.
Solution Approach 2:
The patent segments the collaboration instruction transmission path into two parts: instruction generation at the source IPC and instruction forwarding through the VMS. This segmentation allows the source IPC to send instructions directly without complex processing, while the VMS handles the routing and forwarding function, thereby reducing overall collaboration delay while maintaining simplified system management.
2Loss of time
If direct collaboration instruction sending between front-end devices is implemented, then collaboration delay is reduced, but system control complexity increases
Solution Approach 1:
The VMS serves as a mediator that receives collaboration instructions from source front-end devices and forwards them to target front-end devices. This intermediary mechanism enables direct instruction transmission between front-end devices (reducing delay) while the VMS manages the overall control flow and routing (maintaining system control simplicity).
Solution Approach 2:
Front-end devices are equipped with the capability to generate and send collaboration instructions autonomously without requiring complex centralized control for each interaction. The devices self-manage the instruction sending process, reducing system control complexity while achieving direct communication for real-time collaboration.

AI summary
Embodiments include a front-end device collaboration method, applied to a security and protection system to reduce a delay of a collaborative operation. The security and protection system includes a plurality of front-end devices, and the plurality of front-end devices include a first front-end device and a second front-end device. The method includes: the first front-end device determines that a preset collaboration trigger event exists; and the first front-end device sends a collaboration instruction to the second front-end device, where the collaboration instruction is used to instruct the second front-end device to perform an operation corresponding to the collaboration instruction.
