How to Setup a Security DVR for Remote Internet Viewing
By Patrick Nelson
Digital video recorders that are used for security applications can be networked for remote Internet viewing. This allows the video images that are captured through motion sensing cameras to be viewed through any Web browser anywhere 3G or fixed Internet is available --- including mobile phone or tablet Web applications. Networking also allows messaging alerts and video to be sent via email, notifying the property owner of a potential intrusion. Setting the DVR up for remote viewing involves changing some network configuration settings.
Attach a network Ethernet cable between the DVR and router that you use to connect to the Internet at the property location. Then open the router's interface by entering the router's IP address in a Web browser. Each router manufacturer is different, so you will have to refer to the manufacturer's documentation. Then enter the User ID and password.
Create a static IP address for the DVR by following the router manufacturer's instructions. Make a note of the address and save the settings. Type "ipconfig" from the "cmd" command on a computer that's connected to the network. Write down the router settings that will appear. In particular you're interested in the gateway and subnet mask.
Open the setup menu on the DVR by pressing the "Menu" or "Setup" button, or similar and scroll through to the "Network Settings" area. Choose "Static" as the type of network setup. Enter the static IP address you created, and the gateway and subnet mask from the previous step. Save the settings.
Make a note of the "Port Forwarding" ports that the DVR is set to. They will be in the same setup or menu area and could be "90" and "9000," as an example.
Open the router again and set the static IP address you've set for the DVR to the "Port Forwarding" ports the DVR needs -- from the previous step. The router's documentation will help you. Thus, when the DVR has an IP address, and the router knows what it is and what ports to use, the DVR will be set up for remote viewing.
- Network type options will include Static and also include DHCP, which assigns IP addresses automatically and will let the DVR be found on the network by the router automatically in the same way the router finds a computer automatically. Static will be more reliable.
