2. CONFIGURING THE DVR WITH A ROUTER INTO A LOCAL AREA
NETWORK
The majority of any network will often consist of a single IP address which shares the
internet access through a router. This IP address may be any external (public) static
IP address or any dynamic IP address issued by the Internet Service Provider.
The purpose of a router is to enable multiple personal computers and any other
devices that require internet connection to access the internet simultaneously. Most
routers by default enable (open) commonly used ports so that mainstream
applications such as Hypertext Transfer Protocol (HTTP, Port 80), File Transfer
Protocol (FTP, Port 21), Telnet (Port 23) and Post Office Protocol 3 (POP3, Port 110)
are used.
The DVR utilizes designated ports to communicate to the remote connection therefore
it will be required to be familiar with the router in order to successfully install the DVR
into the network. Port 80 is the default web broadcasting port for most applications,
which is also used by the DVR. Port 7777 is a secondary web broadcasting port for
the DVR in case the Internet Service Provider is blocking Port 80. Port 1104 is the
data streaming port through which the DVR transmits the video data.
Over the next pages, D-Link’s DI-604 was used to illustrate a sample procedure.
