Hi. We have a CCTV server configured with a private IP address. So we just can view the cctv over the LAN. Now we would like to view it over the internet.

Our network desing: WAN LINK (internet connectoin with one public ip) connected to the NAT firewall. private IP is assigned to the lan port of the firewall, from where a utp cable is hooked to the switch. Intenet connection is shared in this way.

Is there any way to configure network settings so that we can view the cctv over the internet?
Thank you

Hi nishad. You can conect your DVR via internet to watch your cctv camera. Setting up DVR can to be used from remote location:

1. Connect your DVR to your router
2. Use menu on DVR to assign internal IP and gateway and port number.

This Local IP must be in the same Gateway range as the Router. If you are unsure check the Router and locate the Status section, or goto the Command prompt of Windows XP and type in ipconfig.

Look for Gateway. If the Gateway is, then you can make the DVR's IP anything from -

Also you will need to use the same SubNet Mask, which is typically, and also use the same gateway.
3. Next find out what port your DVR uses. The easiest way to it is by reading the manual of your DVR. Look for the network section of it.

Also if it comes with network software, check out if in the connection area the software shows the port number.

Also check the Server software/Programming (Network section of it) to see if the port is listed.

In many cases it will be as simple as just Port 80, which is an HTTP port.
4. Set your router to forward chosen port to internal IP address of DVR.

To access the Router itself, use the Gateway you just located. If the gateway is, then enter that into the location edit box of your browser and then click the Enter button. A username and a password are typically required, but it depends on a router. For Linksys use "admin", "admin". By default DLink doesn't require any username or password (It is highly recommended to change the default password).

Once you're logged into the Router, in the Applications & Gaming Section / Servers of the Router, you need to add a Server/Application. Enter the port number and select TCP only. Where it says Port 0 to 0 enter the same port number twice. Or if your DVR uses for example, ports 3550, 4550, 5550, 6550, and there is nothing else utilizing these ports in between, then you can actually just enter one line, 3550 - 6550.

Enter the DVR/Cameras internal IP.

Enable it.

NAME = Anything you want

5. Set up additional entries for as many ports the DVR uses, to the same local IP. Check your DVR manual and it's networking section for all additional ports required. Also check the DVR software itself.

If your router has enough free entries, you can seperate them. Use it like DVR_HTTP for the browser port, DVR_AUDIO for the audio port, etc.

If you are going to use VNC to a PC DVR, then you would need to set up port 5900, and perhaps call it VNC_DVR, for example.
6. You have a static IP so you don't need to use sevices like . You just enter your static IP and your router forwards packets to your DVR.

Excellent information for configuring the cctv security systems. Installing your own CCTV system is straight forward and can be done in a number of ways. The easiest method is to use ready made RG59 cables that carry the cameras power and video signal to a CCTV DVR, which in turn is connected to your TV via a BNC to Scart connector.

Hi all,
Each router is different. There are no general instructions to configure all of them. Manufactures always provide a catalogue for configuring them. So, you should take a help from it.
DVR using
-create an account and login
-go to the account>>my service>>add host services>>add dynamic DNS host
-select host name
-put your PC’s IP address there
-Click add host
• Find DDNS network setting
• Enable it
• Enter username, password from
• Apply the setting

Of course he can! Download a program called True. It gives you complete control and even lets you view your webcam. My security is entirely based on this and cost me ear against the fabric to professional call. I can monitor who is at my door, check all the cams in the house, run a PC in my house from anywhere in the world. The best part is that the software is free and no malware. Remember tho, safety first in the program because when you run a VNC, you put your home at risk of attack from outside.
