9.1 LAN OVERVIEW
The DVR unit can easily be connected to a Local Area Network (LAN) and uses Microsoft’s® powerful and secure
Windows® 2000 operating system. This allows for easy and well-documented instructions on setting up LAN
connections no matter what type of LAN you want to use.
A LAN is a group of computers and other devices dispersed over a relatively limited area and connected by a
communications link that allows one device to interact with any other on the network. Local Area Network is also
called LAN.
Examples of LAN connections include Ethernet, Token Ring, cable modems, DSL, FDDI, IP over ATM, IrDA
(Infrared), wireless, and ATM-emulated LANs. Emulated LANs are based on virtual adapter drivers such as the
LAN Emulation Protocol.
There are a vast amount of reasons why using Microsoft® Windows® 2000 is far superior to other platforms when
running on a LAN. The number one reason is security. Windows 2000 is based on NT technology, which,
historically has boasted the most reliable and secure Operating System in the world. Running the DVR on a
secure network is important to prevent unwanted users from gaining access to confidential information. Unwanted
users can compromise the integrity of the confidential data being stored and viewed, and in extreme
circumstances can cause irreparable damage to the network.
Since connecting the DVR unit to a network can be extremely complex (depending on the network), this Digital
Watchdog DVR manual will cover only the basics. It is suggested that you consult your Vendor or IT Administrator
before attempting to create or connect to a LAN.
