Terminal Automatic Network Initialization via Preconfigured Server Address
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of monitoring cameras into data networks for extensive coverage of complex or spacious areas requires sophisticated expert knowledge, as they need to be manually configured and 'found' within the network, posing challenges with Network Address Translation (NAT) and security risks.
Innovation Solution
A terminal device with a preconfigured server address and network interface allows for automatic initialization and communication setup, bypassing the need for complex router reconfiguration, enabling plug-and-play integration and secure bidirectional communication using a unique device ID and certificate-based authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If monitoring cameras are manually integrated into data networks with expert knowledge, then network configuration and communication setup can be completed, but the installation process becomes complex and time-consuming
Solution Approach 1:
The terminal is pre-configured with a server address in its storage device during manufacturing. This preliminary configuration eliminates the need for complex manual network setup during installation, allowing the terminal to automatically initiate communication with the server when activated.
2Ease of operation
If routers are reconfigured to enable port visibility for NAT traversal, then communication between local subnet and main network is enabled, but security risks increase
Solution Approach 1:
Instead of configuring the router to expose ports to the local subnet (traditional approach), the invention inverts the approach by having the terminal actively initiate communication to the pre-configured server address. This allows NAT traversal without router reconfiguration, maintaining security while enabling communication.
3Reliability
If manual network configuration is performed for each monitoring device, then proper network integration is achieved, but configuration effort and time increase significantly
Solution Approach 1:
The terminal performs self-service during initialization by automatically transmitting the initialization message to the pre-configured server address. The system configures itself without requiring manual intervention, eliminating time-consuming configuration steps while ensuring proper network integration.
4Reliability
If sophisticated expert knowledge is required for terminal integration, then proper network setup is achieved, but ease of installation deteriorates
Solution Approach 1:
The server address is pre-configured in the terminal's storage device during manufacturing. This preliminary action eliminates the need for expert knowledge during installation, as the terminal automatically knows where to communicate with the server, making installation simple for end users.

AI summary
The monitoring of complex or spacious buildings or spaces requires a multiplicity of monitoring devices, for example monitoring cameras, in order to be able to extensively cover such monitoring areas. For this purpose, the invention proposes a terminal 7 having at least one functional device, wherein the functional device is in the form of a sensor and/or actuator device, having a control device 10, wherein the control device 10 is in the form of a digital data processing device, and having at least one network interface 9, wherein the network interface 9 is designed to couple the control device 10 to a network 2, with the result that data can be transmitted from the functional device to the network 2 and/or data can be transmitted from the network 2 to the functional device. The terminal 7 has a client address from a first network 2 as the network, and the terminal 7 has a storage device 11 which stores a server address from a different network 4. The control device 10 is designed to send a message to the server address via the network interface 9 upon initialization of the terminal 7.
