Appendix F: Assigning A Static IP To Your DVR

Appendix F: Assigning A Static IP To Your DVR

When connecting to your DVR through a local area network (LAN), you have the option of
connecting to your system by entering the local IP of the DVR in a web browser. The local IP of
your DVR is like your home’s address. If someone wants to visit you, they need to know your home
address. Similarly, the local IP of your DVR is your DVR’s address.

The problem arises when the local IP address of the DVR changes. Imagine moving every three
months—nobody would ever be able to find you. To solve this problem, we can assign a fixed IP
address—also known as a static IP address—so that the local IP of your DVR will never change.

What’s the difference between DHCP and Static IPs?

DHCP

DHCP (Dynamic Host Configuration Protocol) allows your router to automatically assign an IP
address to devices that are connected to it. DHCP is a convenient method for connected devices
on your router to have an IP address immediately. This allows devices connected to your router to
work right away on the network.

For example, your router assigns an IP address to your laptop, your desktop, and your DVR.

Each time the router restarts (due to power failure etc.), there is no guarantee that the router will
assign the same IP address to your laptop, desktop or your DVR. The router may assign a new
IP address to all of the devices connected to it. This can be a problem if you want to connect to
your DVR locally, since the IP address of the DVR has changed.
