Network system, network apparatus, and network information setting method

Abstract

Problem: an objective is to provide a network system, relating to the setting of each type of necessary information on a network terminal apparatus, with which it is possible to simplify overall management in a management terminal such as a personal computer (PC) in such circumstances as unified setting of each type of information or installing additional network terminal apparatuses, for example. Solution: to ascertain and change setting information of network apparatuses on different subnets from the management terminal, the setting information of other network apparatuses is notified, and a setting information change instruction issued, via a network device whereon the setting information is found.

Description

technical field [0001] The present invention relates to the setting of various information required by network terminal equipment, for example, relates to the unified setting of various information such as IP (Internet Protocol: Internet Protocol) addresses in management terminals such as personal computers (PCs) and network terminal equipment A network system that simplifies overall management in cases such as expansion. Background technique [0002] For the purpose of suppressing crimes and preventing accidents, image surveillance systems are installed in public facilities such as hotels, buildings, convenience stores, financial institutions, reservoirs, and roads. In a general image surveillance system, a camera or the like is used to photograph the surveillance object area, and the captured image is transmitted to a surveillance center such as a management office or a security room via a network, etc., and the supervisor monitors the surveillance object through the trans...

AI Technical Summary

Problems solved by technology

[0008] In addition, when replacing the network equipment of the network video surveillance system that has been set up, sometimes the setting of the IP address set manually is wrong, or the IP address automatically assigned by DHCP (Dynamic Host Configuration Protocol) etc. is wrong, resulting in duplicate IP addresses

At this time, for network devices with duplicate IP addresses, they cannot communicate from the outside.

In this case, it is necessary to go to the installation site of the network device with the duplicate IP address to reconfigure or initialize the settings.
