IP Address Configuration for Network Camera Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In network camera systems, multiple recorders connected to the same network can lead to duplicate IP address registration for cameras, causing performance issues and communication failures, as well as IP address conflicts and changes, which disrupt data delivery between cameras and recorders.
Innovation Solution
A communication device and method that acquires and configures unique IP addresses for terminal devices, ensuring non-overlapping addresses across multiple recorders by identifying unregistered cameras and assigning distinct IP addresses based on information exchanged between devices, preventing duplicate registrations and address changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple recorders automatically assign IP addresses to cameras on a network, then initial system configuration is simplified, but duplicate IP address registrations occur causing performance degradation and communication failures
Solution Approach 1:
The recorder performs preliminary actions by checking whether a camera has already been registered by another recorder before assigning an IP address. The address configuration information acquisition unit acquires registration status information in advance, and the address configuration unit only assigns addresses to unregistered cameras, preventing duplicate registrations before they can cause communication failures.
2Device complexity
If recorders independently configure IP addresses without coordination, then device complexity is reduced, but IP address conflicts occur between multiple recorders
Solution Approach 1:
The system implements feedback by having recorders acquire information about camera registration status from other recorders or terminal devices before assigning IP addresses. This feedback mechanism allows recorders to adjust their address assignment behavior based on the current network state, ensuring unique IP addresses are assigned without requiring complex centralized coordination.
3Adaptability or versatility
If later-connected recorders can reassign IP addresses, then address allocation flexibility is improved, but data delivery from cameras to original recorders is disrupted
Solution Approach 1:
The recorder applies preliminary anti-action by checking the registration status of cameras before assigning IP addresses. The address configuration information acquisition unit acquires information about whether a camera is already registered, and the address configuration unit refrains from assigning addresses to already-registered cameras, thereby preventing the disruption of existing data delivery paths.

AI summary
A communication device is connected via a network, to a terminal device and another communication device for configuring an IP address of the terminal device. The communication device includes an address configuration information acquisition unit and an address configuration unit. The address configuration information acquisition unit acquires, from one of the terminal device and the other communication device, information indicating whether an IP address of the terminal device has been configured, and, in a case an IP address of the terminal device has been configured, information on the IP address configured. The address configuration unit configures an IP address of the terminal device in which an IP address has not been configured and which is not associated with the other communication device based on the information acquired by the address configuration information acquisition unit.
