How to Set Up Internet DVRs

by Dave Wilson, studioD

Digital video recorders (DVRs) can record favorite TV shows, movies and video from security cameras for instant playback or long-term storage to a hard drive. DVRs that have computer network capability enable users to access and playback video from anywhere on the Internet when the network is properly configured. Change settings on the router that connects your network to the Internet to enable DVR video playback access when away from your home or business.

Click the "Start" button on the Windows PC desktop, then click "Programs" and click "Accessories." Right-click on the command line icon and click "Run as Administrator" in the menu that appears. Type "ipconfig /all" in the command prompt and press "Enter." Note the gateway IP address displayed in the command line output.

Open a Web browser such as Internet Explorer, Firefox or Chrome and type the gateway IP address into the address bar at the top of the browser and press "Enter." The Web administration page of the router will appear. Type the administrator user name and password for the router into the text boxes displayed and press "Enter." If you do not know the password for the router, see the list of default passwords at the "List of Default Router Passwords and Default Router IP Addresses" Web page.

Click on the "DDNS" or "Dynamic DNS" button or tab in the router configuration pages. Note the DDNS services supported by the router and then go to the Web page for one of the services and create a new account. Note the DDNS domain name selected during the DDNS service account creation process.

Click on the service in the router "DDNS" or "Dynamic DDNS" configuration page and type the user name and password for your DDNS account into the DDNS user name and password text boxes displayed. Click "Apply" or "Save Settings."

Click the "Applications and Gaming" or "Advanced" tab in the router configuration pages. Click the "HTTP" service from the list of services. Type the IP address of the DVR into the "Server IP Address" or "IP Address" text box. Click "TCP/UDP" or "Both" for the "Protocol" option. Click "Add Server" or "Save Settings." If there is no service list, type a name for the configuration in the "Application" or "Service" text box, type "80" in the "Start" and "End" boxes, click "TCP/UDP" or "Both" for the "Protocol" option, click the "Enabled" box if present, and then "Apply" or "Save Settings." Power down and then power up the router.

Type the DDNS domain name into a Web browser on the Windows 7 computer and press "Enter" to test connection to the DVR.


  • If the DVR setup guide specifies the use of IP ports other than port 80, repeat the last step for each additional port required by the DVR.

Items you will need

  • Administrator password to the network Internet router/firewall
  • IP address of the DVR
  • Router/firewall that supports the Dynamic DNS service
  • Administrator user name and password for the router/firewall
  • Windows 7 computer
