To start off, we would like to walk you through the basics of DDNS for IP cameras to make some preparation for the setup process.

CCTV DDNS is a service that enables you to access the security cameras remotely each time over the Internet with the dynamic IP address.

Put it simply: Your IP cameras with free DDNS service are less accessible to hackers or intruders due to the varying IP address, which makes the remote viewing more secure.

Take Note: These dynamic IP addresses are assigned by your Internet Service Provider (ISP) in your Internet connection and they also assign static IP addresses as well. Mind that you shall keep your IP addresses or IP cameras with DDNS service private in case of any external attacks.

How to Set Up DDNS for IP Cameras: A Step-by-Step Guide (with Video)

Setting up DDNS for IP cameras doesn't have to be a chore. With the video tutorial below, you are able to configure IP cameras with DDNS service within minutes by yourselves.

Step 1. Sign Up and Get a Domain Name from IP Camera DDNS Servers

There is a wide range of DDNS service providers available, free and paid versions as well. You may choose one based on your needs and budget (check here to find the best DDNS providers).

Below we will take No-IP as an example.

Sign In To Create Your Hostname

Note that you need a DDNS service to access your security cameras remotely if your ISP has assigned a dynamic IP to you.

Or else, you won't be able to map the Internet domain names to the IP addresses of DDNS for security cameras.

Step 2. Check the Hostnames/Domains for Remote Viewing

After the successful signup, you will be assigned an IP cameras DDNS hostname or Internet domain.

To check your hostnames, you may log in to your account and click Dynamic DNSHostnames.

Step 4. Login Your Routers to Set Up the Port Forwarding of IP Cameras with DDNS

Before you set up the security camera port forwarding, you may check the value of Media Port of your IP cameras with DDNS by clicking Device SettingsNetwork AdvancePort Settings.

Find The Media Port

Then, you are ready to log in your router and forward the Media Port to the IP address of IP cameras with free DDNS service on the router.

Note: Different routers have different pages to set up and you may refer to the user manual for more details.

Step 5. Check If You Can Access IP cameras Through DDNS

After the successful setup, you can watch the live view of the IP cameras with DDNS on web browsers.

If you are using Internet Explorer for remote viewing, remember to add HTTP:// before the domain name. For the other browsers, just type the IP camera DDNS hostnames in the search bar and you are ready to go.

Here are two examples:

For IE:

For other browsers: yourhostname.

Still find it difficult to configure DDNS for IP cameras on your own? Below are 2 simpler alternatives that you may be interested in.

Top 2 Easiest Alternatives of IP Cameras DDNS Service

If you want to skip the IP cameras DDNS settings or prefer other simpler ways to view IP cameras over the Internet, you may consider the two alternatives as followed.

Apply P2P IP Security Cameras – The Most Convenient Option

P2P IP security cameras apply peer-to-peer technology that simplifies the connection between the security cameras and phones or PCs, meaning that you can access the security cameras remotely easily without DDNS IP camera setups.

And this is how P2P security cameras work:

Each P2P security camera comes with a unique ID number (UID) registered and integrated at the developer level. By typing in the UID and the password, you can watch the live view of the P2P security cameras on software with a stable Internet connection in a breeze.

Below we will take Reolink Argus 2 as an example to show you how easy the P2P security camera setup is.

Apply Security Cameras with Static IP Addresses – Another Workable Way

Supposed that you don't want to configure DDNS for IP cameras or pay for DDNS service subscription fees, you may choose to access the security cameras remotely with static IP.

Generally speaking, ISP won't assign you static IP addresses but you can request one from your ISP with justified reasons at extra cost. If you do not plan to spend money on static IP, you can choose P2P IP cameras as the budget-friendly security options.

Bonus: In order to access the security cameras remotely in a more secure manner, you may apply multiple methods, such as upgrading firmware and changing passwords (also read this post to learn more feasible methods to protect IP cameras with DDNS from hacker attacks).

Troubleshooting Tips for IP Camera DDNS Service Errors

Why are my IP cameras with DDNS inaccessible over the Internet? How to solve issues that DDNS service for security cameras is failed? What should I do when the DDNS for IP cameras is not working?

You have encountered these problems after finishing IP camera DDNS settings. Here are several useful tips for you to get out of the trouble.

Tip 1. Always Update IP Camera DDNS Firmware to the Latest Version

Outdated firmware is one of the major reasons of IP camera DDNS service errors. To fix previous bugs and provide new features, top IP camera manufacturers and DDNS servers keep launching new versions of their firmware.

Therefore, by updating the firmware, you are less likely to meet network issues of DDNS security cameras.

Tip 2. Check the Firewall Settings of the Routers

Another possible reason for failed DDNS service for IP cameras can be the specific firewall settings of the routers. If your routers have blocked unknown IP addresses, you won't be able to access the security cameras remotely.

So, altering the firewall settings on your routers to permit dynamic IP addresses will help reduce network failure of IP cameras with DDNS service.

Tip 3. Confirm If You Have Set Up IP Cameras with DDNS Port Forwarding Properly

Remember that without port-forwarding setup, you cannot stream the live feed of CCTV cameras with DDNS when you are away from installation spots.

To ensure smooth remote viewing of IP cameras with DDNS, you may log in your routers to make sure that you have done the port-forwarding properly.

Tip 4. Make Sure That Your Internet Connection Is Also Dynamic

As we have mentioned above, you can access the IP cameras with DDNS remotely with a dynamic IP address each time only when the internet connection assigned by your ISP is also dynamic.

In order to avoid possible network issues, you need to make sure that your Internet connection is also dynamic before you configure DDNS on IP cameras (follow this tutorial to check if your IP is static or dynamic).

    Hello! I have a remote camera system at a home in an area where the only reliable ISP is Verizon Wireless (4G LTE). I am a bit confused because my research led me to believe that DDNS (even through is not effective when your ISP(VW) is using NAT behind a firewall and I want to monitor my cameras from either a remote PC connected to the internet via another public ISP or from my Verizon Wireless smartphone (The remote PC situation apparently does not allow the proper implementation of Port Forwarding(?) and that the only way I will be successful in setting up remote PC viewing of my IP camera system is by purchasing a VERY expensive static IP address from VW, my ISP. I kind of understand how the smartphone monitoring could work because presumably my Verizon Smartphone ”understands” the Private IP translation that VW uses.

    HOWEVER,...I have a highly technical person willing to help me who says that he has successfully done what I want to do with monitoring from a remote PC, although perhaps via a different 4G LTE carrier , without buying the Static IP address but just by using My problem is that while I am much more technical than the average person and I do understand the basic concepts of IP and routing, I don't exactly understand HOW gets around the NATS system used by Verizon Wireless (which may also be double NAT?) which apparently assigns a Private IP address equivalent . I don't want to be skeptical of someone who is admittedly much more technical and experienced at this than I am. Is the DDNS the exact equivalent of a static IP? I do believe that my NVR software is very capable. It is basically an HIK firmware based router. Pls. advise. THANK YOU

      Hello, Stan, generally speaking, a static IP is an ideal option for the business and costs more while the DDNS services are sufficient and affordable for individual usage. To learn more about the DDNS service provided by, it is best to consult the professional from the website and they will share with you more about the technical info. Mind that you can only access your security systems via static IP or dynamic IP after connecting your systems to a router or the Internet. Hope this helps.
