Remote Access: IP addresses

Public and Private IP Addresses

The IP address used by the DVR, whether entered manually (STATIC) or assigned by

the dynamic host (DHCP) is the private IP address of the DVR. The private IP address

is used to locate the DVR on your private network. However, to access the DVR from

a remote location via the Internet, you’ll need to know your home network’s public

IP address.

What’s the di erence?

The IP addressing system that the Internet utilizes at the moment supports up to

(approximately) 4 billion addresses. That is a lot, but it’s not enough for every device

connected to it (computers, phones, video game consoles, DVRs, servers, televisions

and even some refrigerators can all have Internet connections) to have individual

addresses. This problem is solved by assigning an address to each sub-network on

the Internet. This means that all LANs, such as your local network in your home or

o ce, will have a public IP address which will allow you to  nd that network from

anywhere connected to the Internet.

This means that all devices connected to your network share one public IP address.

To di erentiate devices on your network, your network has its own IP address range,

and this is what is referred to as your private IP address. You’ll need to know the

private IP address if you’re using STATIC addressing and/or are Port Forwarding (i.e.

not using UPnP).

If you’re using DHCP addressing and have UPnP enabled on both the router and the

DVR, then you may not need to know the private IP address at all.

How do I  nd these addresses, and what should I do with them?

If you’re setting up a dynamic network (DHCP) then you don’t need to know the

private IP address of your DVR (it’ll probably change over time, anyway). Rather,

you only need to de ne the Media Port and Web Port. If you’re not using UPnP (if

possible, use UPnP - it’s just awesome) then con gure your router to forward these

ports to the DVR.

If you’ve con gured your network using STATIC IP addressing, then you’ll be entering

the private IP address directly into the DVR. Then you’ll need to choose your Web Port

and Media Port. Finally, you’ll have to con gure your router to forward your selected

ports to the private IP address of the DVR.

Finally, to learn your network’s public IP address, you’ll need a computer with Internet

access connected via the same network as the DVR you’re con guring. Then, open

an Internet browser window. In the address bar, go to

www.whatismyip.com. Your

public IP address will be displayed instantly!

10) Pause: During playback, will pause

the current recording and leave a still-

frame on screen. In live-viewing mode,

this will activate the auto-sequence

mode, where the display automatically

cycles through the available camera

signals (this must be correctly con gured

and enabled to function correctly).

11) Play: If pressed in live-viewing mode,

this will take you directly into playback

mode, and begin playing the most

recent recording. In playback mode, use

it to resume playback after pausing or

stopping a recording.

12) Fast-Forward: During playback,

this will speed up the footage. Press

multiple times to increase the speed of

the playback. When navigating through

menus, this button will move the cursor

to the right.

13) Stop: In playback mode, pressing

this button will stop playback.

14) Record: Press to immediately start

recording. This acts as a manual override

to the schedule and motion recording

modes. For a channel to be recorded in

this mode (or any other) it must listed as

‘active’ in the Camera Setup and Record

Setup menus.

15 ~ 18) Arrows: Move the cursor in the

selected direction in the menus.

19) Select: The equivalent of Enter/

Return on a computer keyboard. Use this

button to (as the name suggests) select

an option in the menus, or to con rm an

entry.
