NVR Automatic IP Camera Connection via Zero-Config
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users without expertise in IP network settings face difficulties in manually configuring network settings for both NVR devices and IP cameras, leading to errors and increased time in establishing a connection between them.
Innovation Solution
A system for a network video recorder (NVR) device that automatically allocates a non-duplicate IP address using a zero-configuration scheme, broadcasts camera response requests, and analyzes responses to identify and register IP cameras, reducing user intervention through an intuitive user interface and security level management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual network settings are configured for NVR and IP camera, then connection can be established, but user expertise in IP network settings is required and setup time increases
Solution Approach 1:
The NVR device automatically performs network configuration tasks including IP address allocation, subnet mask setup, gateway configuration, and domain name server settings without requiring user intervention. The system self-configures the network connection by detecting the IP camera and establishing communication parameters autonomously
Solution Approach 2:
The NVR device pre-configures network settings and prepares connection parameters before the actual connection is needed. The system performs preliminary network setup, including allocating IP addresses and configuring network protocols, so that when the IP camera is connected, the network environment is already ready for immediate communication
2Reliability
If manual network settings are configured for NVR and IP camera, then connection can be established, but errors may occur due to lack of user expertise
Solution Approach 1:
The NVR device automatically performs network configuration tasks including IP address allocation, subnet mask setup, gateway configuration, and domain name server settings without requiring user intervention. The system self-configures the network connection by detecting the IP camera and establishing communication parameters autonomously
Solution Approach 2:
The NVR device receives camera response information from the IP camera and analyzes it to determine whether the camera is available to be registered. The system uses feedback from the camera's response to verify successful connection and adjust configuration parameters accordingly, ensuring reliable connection establishment
3Reliability
If security level is set to prevent exposure to other NVR devices, then security is improved, but camera cannot be registered by other NVR devices when disconnected
Solution Approach 1:
The security level of the IP camera is dynamically adjusted based on its connection state. When connected to an NVR device, the camera sets its security level to respond only to that specific NVR. When disconnected, the security level is automatically initialized to allow other NVR devices to detect and register the camera, providing flexible adaptability to different operational states

AI summary
A system of a network video recorder (NVR) device for automatic connection to an IP camera is provided. The system is implemented to make it possible to automatically establish a connection between the NVR device and the IP camera while reducing a user's intervention, and thereby a user not having enough expertise knowledge of IP network settings may be able to avoid experiencing inconvenience in manual settings, and also it is possible to prevent errors which may occur in manually adjusting the network settings and to prevent unnecessary time wasted on the network setting management process.
