DS NVR Prospective Network Configurations

1. Introduction

1.1 Purpose

This document discusses options for using dual network cards in a DS NVR system.

1.2 Definitions, acronyms, and abbreviations

1.2.1 Acronyms

DS NVR – DigitalSENTRY Network Video Recorder

NIC – Network Interface Card

1.2.2 Definitions

Router—a communications device that determines the best path between networks for optimal

performance. Routers are used in complex networks of networks, such as enterprise-wide networks

and the Internet.

Network switch—a computer networking device that connects network segments. It is often used to

replace network hubs. A switch is also often referred to as an intelligent hub.

2. Summary

IP cameras by nature can generate significant amounts of network traffic, resulting in a detrimental

effect on a company’s corporate network. Some IP camera installations can benefit by separating the

network traffic generated by the IP cameras from the company network. There are several ways to

accomplish this task.

3. IP Camera Network vs. Corporate Network

In each of these examples, all IP cameras and IP video servers are physically connected to their own

network backbone. Large numbers of IP cameras can benefit from a gigabit network switch. The

TCP/IP address scheme for the IP camera network must be different than the corporate network.

For example, the IP camera network can use the private address scheme 192.168.7.1 through

192.168.7.254, and the company network can use 10.159.16.*. The following examples discuss

several configuration options, including their advantages and disadvantages.

The corporate network in this document is typically used for printing, file sharing, email, and Internet

access. Some environments require the security (IP network) to be physically separated from the

corporate network, whereas other environments need to share resources across the networks.

4. Separate Physical Network

This method is the simplest to implement and support. All the IP cameras and IP video devices share

the same network backbone as the DS NVR system and all DigitalSENTRY client computers.

Each IP camera, IP video server, and DS NVR system has a static TCP/IP address. Any client
