Port forwarding is the process that your router or firewall uses to sort the right kind of network data to the appropriate port. Computers and routers use ports as a way to organize network data. Different types of data, such as web sites, file downloads, and online games, are each assigned a port number. If your DVR has an online viewing feature, then port forwarding is a necessary step which opens a path, or a port, on your home or business network that lets you view your DVR’s video feed via the Internet.
An IP (Internet Protocol) address is like a street address in a way. It provides information on where you are but not who you are or how to get there. When you access the Internet on your computer or smart phone, you communicate with other networks using your IP addresses, letting other devices know where you are. IP addresses come into play when setting up a DVR for remote Internet viewing. Every DVR that is capable of communicating over the Internet is assigned an IP address that uniquely identifies and distinguishes it from other DVRs online. If your DVR has the online viewing feature, then you will need to find out the IP address. Sometimes, the IP address will be noted in the product manual, but if not, you can easily find it by visiting www.whatismyipaddress.com.
You also need to know what kind of router you will be using to get your DVR online. There are hundreds of brands of routers on the market, such as D-Link, 2-Wire, Linksys, and Belkin. Look at your router to determine which type you own.
