In the context of IP video security, port forwarding is one of the processes to make a camera or NVR accessible via an open port from anywhere in the world with an Internet access. An alternative method is P2P, which we have covered here and here.
Although it is a pretty straightforward process, it may be difficult for someone who has not done this before.
In its simplest, what port forwarding does is create an opening for outside access. The ports that you open enable people with who have the ‘keys’ access your network and pull data from it, such as video and audio data from your cameras.
Step 1: Identify your IP Address
The first piece of information you’re going to need is the IP address of your router.
Before you can access your router, you'll need to have an Internet connection, both to show you the proper address and to allow you to connect to the router.
If you use Windows OS:
In the ‘Start’ search bar type ‘cmd’ or ‘command prompt’ and press enter to open ‘Command Prompt’
Type ‘ipconfig’ in the Commands Prompt and press enter
This will show you your ‘Default Gateway’ and ‘IPv4 Address’ or ‘IPv6 Address’ (4)
If you use IOS, then have a look here, where we covered this step in some detail.
Step 2: Configure Your NVR / Camera Network Settings
Use a device scanner (such as IVMS for Hikvision) to identify your device’s settings change (if necessary) your device network settings in line with your router IP details.
Step 3: Login to your Router
Once you have assigned the IP to your NVR / Cameras, you need to login to your router through your internet browser. To do this, open your browser and enter the Gateway (router) IP address as a URL and press enter.
You should see a log in page specific to your internet provider. Using your router’s username and password log-into your router. If you do not have this information, you’ll have to contact the maker of that router and have them walk you through the steps of getting a new one or resetting the router so you can use the original default login information.
Step 4: Forward your port
No two router pages look exactly the same, so you'll have to look around your router's page for the port forwarding section. In most cases, the easiest way for you to find this section is by checking your router's manual or online documentation.
In your router settings, navigate to Network Setting (which, depending on your router model, can also be called ‘Advanced Settings’ ‘Port Management’ ‘Port Forwarding’, ‘Applications’, ‘Gaming’, ‘Virtual Servers’, ‘Firewall’, and ‘Protected Setup’ or similar).
The port you are going to be forwarding is 80. The IP address to enter for all port forwarding is the IP address of your NVR (e.g. 192.168.1.9).
