CHAPTER 4 MAIN MENU SETUP
4.6 NETWORK CONFIGURATION
This section covers setting up your DVR so that it can be remotely monitored from another
computer on your network, over the Internet or from mobile wireless devices. E-mail alerts
are also configured here and you can set up a DDNS service for a more reliable connection
to your remote devices. The four tabs in this window are
Network
,
Sub-Stream
,
and
Other Settings
. If you will only be monitoring the DVR from another computer on your
network, you will only need to use the first three tabs.
It is important that your DVR is connected to your network router and that the router is
powered on before proceeding.

Network Tab
HTTP Port
– This is the port the DVR
will occupy on your computer
network. When accessing the DVR
remotely from the Internet, you will
need to enter your network’s IP
address (obtained in the next step)
in the address bar of an Internet
Explorer window. For example:
http://192.168.0.25
Optain IP Address Automatically
– Clicking this box will obtain the IP address, subnet mask,
and gateway IP from the router.
PPPOE
– Selecting this enables Point-to-Point Protocol over Ethernet (PPPoE) which allows
you to directly connect your DVR to the Internet through your modem. Do not use this
unless required by your Internet Service Provider (ISP) or if you are already connected
to a router. Contact your ISP for your account information including user name and
password. The
TEST
button will verify that your information is correct.
NOTE!
The default value is 80. If port 80 is already occupied by another device
on the network, then another port will need to be selected. Choose another
number in the same range; 81-89. In this case, you will have to add the port to
the IP address when entering it into the Internet Explorer window. For example,
if the port is now 82, then you will need to enter http://192.168.0.25:82
Substream Tab
The substream is the data that is sent to remote monitoring devices. Due to bandwidth
concerns, these data streams are generally smaller than those sent directly to the DVR itself.
These streams run in parallel with the main stream sent to the hard drive and they do not
affect each other.
Definitions and descriptions of network configuration:
Parameter
Definition
HTTP Port
The network port number for accessing the DVR via Internet Explorer. The default
port is 80
Server Port
The port number for data. The default port is 6036
Static IP
IP Address
The IP address of the DVR on your network
Subnet Mask
The server’s subnet mask
Gateway
The gateway of the router
DNS Server
The address of the Domain Name System (DNS) server
PPPoE
User Name
User name of the broadband account
Password
Password for broadband account
Substream settings are configured in the
same manner as that used for the primary
stream settings in the
Record Bitrate
tab in
Section 4.3
Certain settings will be
grayed out and cannot be changed due to
throughput concerns. The definitions are
repeated for your convenience:

Parameter
Options
What it Means
Resolution
D1, CIF
D1 = Full TV resolution, CIF = 1/2 D1. D1 takes more
room on the hard drive than CIF
FPS
1-30
Frames per second. More frames makes for smoother
video but takes up more room on the hard drive.
Encode
VBR, CBR
Variable Bit Rate versus Constant Bit Rate. VBR
provides better image quality for video with motion in
it, but at the expense of a larger file size.
Quality
Lowest – Highest
Only available when VBR is selected. The higher the
quality, the more drive space required.
Max Bitrate
256-2084kbps
Your network may not have enough bandwidth to
handle maximum rates from all of your cameras.
Adjusting these settings to suit your network will
improve performance and on-screen image quality.
