For proper use of the router, strictly follow the steps 1 to 5.

Configure your router, computer and DVR equipments as described in the following steps.

Step 1. Connecting Cables

Step 2. Connecting your local computer to the router

Step 3. Connecting DVR to the router

Step 4. Connecting the router to the internet service line

Step 5. Configuring router’s port forwarding

Step 6. Accessing DVR using DDNS service in dynamic IP environment

What is port?

As usual, the <HTTP Port> uses port 80.

If the port is not setted, it is automatically regarded to 80 in http protocol.

For example, http://www.yahoo.com and http://www.yahoo.com:80 are regarded the same.

Hence, if the <HTTP Port> has been changed other than 80, you need to specify the address as: http://<IP
ADDRESS>:<HTTP Port>

` ex) http://192.168.1.200:80 to connect to the DVR using internet browser.

(Only when the port is set to 80, you can omit the port in the address.)

It is recommended to set <HTTP Port> to port number between 1024 and 65535.

If the port is not set to 80, accessing can be restricted depending on your service provider’s security policy or firewall
configuration.

DVR uses <HTTP Port> and <Device Port> for web connections.

<HTTP Port> is used for accessing DVR by using an internet browser.

<Device Port> is used for receiving video from DVR to internet browser.

J

` When configuring multiple DVR, <HTTP Port> and <Device Port> settings should be configured differently for each

device.

` ex) DVR #1 Device Port : 4520, HTTP Port : 80

DVR #2 Device Port : 50000, HTTP Port : 2000

Step 3.2 Checking DVR connection on your computer

1. Run the Internet Explorer, and enter the <IP ADDRESS> and

<HTTP Port> of the DVR into the address, and press [Enter].

` ex) http://192.168.1.200:80

2. If the connection establishes properly, the Web Viewer screen

appears.

3. If the connection fails, check Steps 1, 2 and 3 to confirm the

connection setup.

English-6

Step 4. Connecting the router to the internet service line

Internet connection setup method and steps may differ from routers, check your router’s setup method.

Connection types according to your internet service

Setting the internet connection may differ from internet service types, check your environment before proceeding and
select the appropriate connection type.

~ DHCP(Dynamic) : IP environment which allocates IP address automatically.

~ Static(Fixed) : IP environment using public IP addresses.

~ PPPoE: Common in DSL environments, which requires ADSL access ID and password.

Ask your internet service provider for the user ID and password.

` Name of each type described above may differ from router manufacturers.

Step 5. Port forwarding

Port forwarding should be configured for accessing from the outside of the router network to a computer or DVR is connected
to the router.
Configure your router’s port forwarding as followings.

What is port forwarding?

It is a port mapping function of <Router’s WAN (Internet) IP: Port> to <DVR’s IP: Port>, that helps opening a
communication channel between inside and outside of the private LAN

Since one DVR uses 2 ports for communication, port forwarding setup for both 2 ports should be configured.

J

` If only <HTTP Port> is configured for port forwarding:

Accessing through the web browser is possible but video is not received since the <Device Port> for video data communication is
not configured for port forwarding.

If only <Device Port> is configured for port forwarding:

Accessing through the web browser is impossible since the <HTTP Port> for the communication is not configured for port
forwarding.

In the below, port forwarding methods for each router are explained.

For other routers not guided herein, refer to the user manual of the router.

Step 6. Accessing DVR using DDNS service in dynamic IP
environment

Since the router’s WAN IP address may vary in xDSL/Cable connections hiring dynamic IP allocations, DDNS (Dynamic Domain
Name Server) service is provided for accessing the DVR with fixed DDNS address in dynamic IP network environments.

Step 6.1 DVR DDNS configuration

1. Use the up/down buttons (▲▼) in <Network> window to move to

<DDNS>, and press [ENTER] button.

2. Use virtual keyboard to enter user inputs.

` Refer to “Using Virtual Keyboard”.

~ If selected <OFF> or <iPOLiS>, input fields are deactivated.

~ If you select <iPOLiS>, the “DDNS Host Address” item will be

displayed.

- Type your set ID in <Product ID> field.
More specific information is in “iPOLiS DDNS Setting”.

- Select <Use> in <Quick Connect> menu. After finishing

“iPOLiS

DDNS Setting”, you can connect your DVR set with the address <http://www.samsungipolis.com/
SDRC75300HOMEDVR>.

` The router used should support uPNP Port Forwarding function.
` Note that uPNP Port Forwarding does not support UDP protocol.
` If the program fails to read uPNP Port Forwarding List, try again after restarting the computer and router.

3. When the DDNS setup is done, press <OK>.

Step 6.2 Accessing DVR using DDNS address

1. Run the Internet Explorer and enter the DDNS address found in

Step 6.1 into the address field end press [Enter].

2. DVR’s Web Viewer screen appears.

3. If failed with accessing, go to the Step 6.1 and check the settings

again.

M

` It may take up to 10 minutes for updating the router’s IP

address recorded in the DDNS server. When failed with
accessing, retry after 10 minutes.
DVR reports its IP address to the DDNS server at every 10
minutes.

Configuration completed.

By remembering the DDNS address, ID and password, you can connect to your DVR from any computer that is
connected to the internet.
For further operating information, refer to the user manual.
