Surveillance System Response Code Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surveillance systems for large complexes face inflexibility and high costs in reconfiguring camera-monitor connections, and experience network burdens due to high image resolution demands from multiple cameras.
Innovation Solution
A surveillance system utilizing response codes stored in a memory for camera image data retrieval, with monitors generating codes to connect image data through a connection medium, allowing dynamic allocation of IP addresses for cameras and monitors, enabling flexible configuration and reduced bandwidth requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If crossbars are used to link cameras and monitors, then connection is established, but the system becomes inflexible and expensive to reconfigure
Solution Approach 1:
The patent replaces the mechanical crossbar connection system with a digital network-based connection system. Cameras and monitors are assigned unique identification codes (such as IP addresses) and communicate through a network switch, eliminating the need for physical crossbar wiring. This allows flexible reconfiguration by changing software assignments rather than physically rewireing hardware, directly resolving the contradiction between connection reliability and reconfiguration flexibility.
2Manufacturing precision
If high resolution images are transmitted from multiple cameras, then image quality is maintained, but network burden increases massively
Solution Approach 1:
The patent extracts only the essential identification information (response codes) from the full image data and transmits this minimal data set through the network for routing purposes. The actual high-resolution image data is transmitted directly from cameras to monitors through the network switch using the extracted routing information, reducing network burden while maintaining image quality. This separates the routing function from the data transmission function.
Solution Approach 2:
The network switch acts as an intermediary that receives response codes from monitors, translates them to camera identification codes, and directs the corresponding high-resolution image data flows. This intermediary function allows the system to maintain high image quality while managing network traffic efficiently through intelligent routing rather than broadcasting all data to all devices.
Data Source
AI summary
A surveillance system with cameras, monitors and a connection medium. Provided in this connection are a response code memory for the storage of response codes by which image data can be retrieved by cameras and response code generation media which are allocated to the monitors and generate response codes which indicate which cameras should retrieve image data, whereby the connection medium is designed for the purpose of through-connecting image data to the monitors in response to the response codes generated by the response code generation media allocated to the monitors.
