HOW TO CONNECT DVR/CCTV CAMERA TO THE INTERNET

If you are thinking it is possible to connect your DVR/CCTV camera to Internet
via USB modem via a lap top, The answer is no! You are trying to set up a VPN on an internal network? You must have a switch or router or modem or something somewhere? You are going to have a hard time keeping track of an IP address with a 4G stick.

Now,  here is what you need to link your DVR/CCTV camera to the internet.

Requirements:
1.Your Ethernet adapter or Router if you it branded router from network providers 
they should assign your an IP.

3.USB modem if you want to make use of usb Internet access if the ISP allowed it.

4.DVR depend on the number of camera your are using if it 8 camere=8 channel DVR
16 camera=16 channel DVR etc

How to connect your DVR with USB Mordem.

1. Buy GMS Modem (look like flashdisk)
2. Buy Router 3.75G 

3. Plug GSM to Router, 
4. ensure that the Modem can be detected, and Connected to Internet
5. Set your Router to forward yor DVR Port
6. Connect your DVR to your Router

Connecting your DVR to Internet:
Connect your DVR to your router
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 192.168.1.1, then you can make the DVR's IP anything from 192.168.1.2 - 192.168.1.255. and ping the ip to know whether if there is any other one or application using it if there is find another number.

Also you will need to use the same SubNet Mask, which is typically 255.255.255.0, and also use the same gateway.
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.
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 192.168.1.1, 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.

TCP/UDP = TCP 
LOCAL IP = 192.168.1.200 
ENABLED = CHECKED 

OR 

NAME = Anything you want 
Port = 3550 TO 6550 
TCP/UDP = TCP 
LOCAL IP = 192.168.1.200 
ENABLED = CHECKED

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 separate 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.

Now you have successfully connected you DVR to Internet to view your residence or office from any part of the world Type the ip address of your DVR followed by port no eg,192.168.1.1:8080

That is all, if you Have any question do not Hesitate or recommendation on the typeof cameras and DVR to get suite the surveillance location of your home and offices and where to get them at reasonable amount.
