Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If brand-specific converters are used to convert analog signals into digital formats, then video/audio transmission clarity is improved, but device compatibility and system setup complexity deteriorate
Solution Approach 1:
The patent implements a universal conversion device that can handle multiple video/audio formats and protocols (analog, digital, different resolutions) through a single platform. The device includes a format detection module that automatically identifies input formats and a conversion module that transforms them into standardized digital outputs, eliminating the need for multiple brand-specific converters and enabling seamless integration of diverse surveillance devices into one system.
2Adaptability or versatility
If multiple brand-specific converters are deployed to support different surveillance devices, then device compatibility is improved, but network bandwidth consumption and system complexity increase
Solution Approach 1:
The patent consolidates multiple conversion functions into a single unified conversion device that processes all video/audio streams through one system. The device includes a centralized control module that manages multiple input sources and a single standardized output interface, reducing redundant data transmission and network bandwidth consumption while maintaining support for multiple device types and formats.
3Reliability
If traditional analog cameras with brand-specific converters are used, then analog signal compatibility is maintained, but system expansion and management become difficult
Solution Approach 1:
The patent introduces a universal conversion device as an intermediary between traditional analog cameras and the digital network system. The device includes an analog input interface that maintains compatibility with legacy analog cameras and a digital output interface that connects to the IP network, serving as a bridge that preserves analog signal compatibility while enabling easy system expansion and centralized management through standardized digital protocols.
Data Source
AI summary
A surveillance system of multiple video/audio source is provided, which includes a first surveillance device, a second surveillance device, a network video interface conversion device, and a user device. The first surveillance device acquires first surveillance data, and the second surveillance device acquires second surveillance data. The network video interface conversion device is connected to the first surveillance device and the second surveillance device, and sets the universally unique identifiers (UUIDs) and ports of the surveillance devices via a conversion protocol compliant with the open network video interface forum (ONVIF). The user device is connected to the network video interface conversion device, and the first and second surveillance devices are defined as independent network surveillance devices.
