Streaming IP cameras over Internet can undoubtedly provide you peace of mind while you are away, yet many of you may labor your wits over setting up your IP camera for remote viewing and still end up in failure.

So how to remotely view your security cameras using the Internet? What to do if you can view the IP camera through your LAN IP address but fail to access it from another computer network or via different WiFi connections?

In this post, we’ll show you the two ways to set up an IP camera for remote viewing step by step, through which you can easily learn how to watch CCTV cameras from anywhere using Internet.


Stream IP Cameras over Internet via Manufacturers’ App/Client

The TOP 1 method (easiest and most convenient) for you to set up an IP camera for remote viewing, is to use the manufacturer’s App or Client.


The App and Client are totally designed for the security cameras by manufacturers, so unlike the third-party software, you don’t need to be concerned about any compatibility issues when watching CCTV cameras from anywhere using Internet.

On top of that, the security camera providers will also release new software versions regularly to unlock some improved features.

Thanks to the P2P technology, you are able to watch your CCTV cameras from anywhere using Internet in a breeze, like checking on your remote shed or cabin from the comfort of your home.

In our test, we used Reolink RLC-410 security camera for the remote access setup via UID method. And below are the 3 simple steps to configure an IP camera on Internet for remote viewing within less than 2 minutes.

Step 1: Download the Reolink App or Client to your phones or computers.

Step 2: Launch the app and enter a unique ID number (UID) to add the camera device.

Step 3: Click the Reolink RLC-410 camera on the App or Client and you can view your IP camera over the Internet outside the home network.

Security Camera Remote Viewing

In fact, not only yourself, your wife and parents can also stream your IP camera over Internet simultaneously. (Read this to learn how to access IP cameras on multiple devices at one time.)

For Reolink battery powered security cameras, 8 users can remotely view the IP cameras online via the cellphones at the same time. And 12 users can simultaneously watch the Reolink non-battery powered CCTV cameras from anywhere using Internet.

This is certainly the easiest way to stream your IP cameras over Internet, no matter you want to monitor your boats beside your house or view your vacant properties/barn/farm/business from your home.

Security risks associated with IP camera setup for remote viewing?

Fear NOT!

Although the P2P applications contain some safety vulnerabilities, security camera providers can take advantage of the encryption technology, such as SL encryption, WPA2-AES encryption and SSL-TLS enabled to prevent exposure of your privacy.

And Reolink is the one.

Since the security camera remote viewing free software is required if you want to set up your IP camera (e.g. Reolink, Amcrest, Swann, etc.) for remote access via the UID, it may not apply to you if your camera provider doesn’t offer such IP camera remote viewing software.

Important Note: Broadly speaking, the camera software provided by the sellers can only allow you to watch CCTV cameras of the same brand from anywhere using Internet. It can’t work with the security cameras of other brands.

Set up IP Cameras for Remote Viewing via Port Forwarding

So what is the alternative to the UID method for you to stream IP cameras over Internet?

And how do you set up a security camera to see it remotely via a web browser?

Below is a step-by-step guide to help you set up your IP camera for remote viewing by port forwarding, which applies to the IP camera remote access via different WiFi connections of all security cameras brands as well as the NVR remote viewing.

Step 1: Find the IP Address of Your Security Camera

To watch your CCTV cameras from anywhere using Internet, the first thing is to find your camera IP address.

Typically the security camera software has a page that displays your network status, including the IP address of your security camera.

Taking Reolink C1 Pro for example, after launching Reolink Client on your computer and logging into the camera, you can click “Device Settings” and go to “Network > Status” to find you camera IP address.

Or you can also refer to your router configuration software and look for a screen that shows the IP addresses of attached DHCP clients.

Step 2: Check the WAN/External IP Address of Your Router

You can visit here to get your current WAN IP address of your home network.

But here comes the question: your external IP address may keep changing because most ISPs allocate dynamic IP addresses to their customers.

If you want to save the trouble to check the WAN IP address of the router every time you access the IP cameras from Internet, or you can’t find out the new WAN IP address when you are away, use the DDNS service to configure your IP camera on Internet for remote viewing.

The main benefit of DDNS is that it will allocate a host name to your camera so you don’t have to remember your IP address, making it much easier for you to watch your CCTV cameras from anywhere using Internet.

Bonus: You may refer to the procedures about how to access your Reolink IP cameras from Internet remotely via DDNS.

Step 3: Check the Camera Port Numbers & Forward Ports to the Router

The port numbers are used when you need to set up an IP camera for remote viewing. Routers rely on ports to limit data which can access your IP camera and differentiate between multiple devices.

If you have two security cameras on your network and you want to view both IP cameras online remotely, remember to use different port numbers. (You may chage the port numbers based on your situations.)

After you have obtained the “HTTP port” and “RTMP port” from the camera device settings, the next step to configure security IP cameras for remote viewing is to log into the web interface of your router and set up the port forwarding rules (shown as below).

Port Forwarding

Step 4: Enter the URL Address

Now that you have obtained all the essential information, the final step to set up an IP camera for remote viewing is to open your web browser and enter the URL address, which consists of your WAN IP address and the port number.

For example, if your WAN IP address is, and the HTTP port is 8001, the URL address you enter on the web browser should be “”. And then you can view your security IP cameras online free outside your home network.

No Internet? And You Want to View Security IP Cameras Remotely

“Can I view my IP cameras remotely without Internet in my barn?”

Well, that depends on which type of security cameras you install.

For the wired IP cameras that connect to a broadband modem or router through Ethernet cables, and the wireless security cameras that use a WiFi router for data transmission, Internet is required if you want to setup these IP cameras for remote viewing.

BUT your hands are not tied even if you want to remotely access your IP cameras without Internet.

Thanks to the advanced technology in the security camera field, the cellular-based security cameras that operate on the 4G/3G mobile data are designed to solve the “no Internet” dilemma.

So you can remotely access your security IP cameras on your smartphone via the UID method in areas with limited or no Internet, such as your barns, farms, sheds, cabins, vacation homes, campsites, hotels, etc.

  • Christo Boshoff

    Hi there …my brother in law is staying in bredasdorp…and their farm is in calvinia…35km outside of town …there are wifi on the farm …will he be able to install four ip cameras and be able to view it on his smartphone

    • Hi Christo, yes, as long as the cameras can connect to the WiFi in the farm and the WiFi signal is stable, your brother would be able to view all the four IP cameras on his smart phones using the cellular data or the WiFi network. Hope it will help.

  • Matt Zuba

    I’m trying to connect to my camera’s from my WiFi at work and it’s failing (but works fine on 4G). What protocol and ports need to be opened on the CLIENT side to allow viewing the cameras?

    • Jenny Hu

      Hi Matt, please make sure the remote access settings are configured correctly by following the procedures in the post. Check if the port is closed by the router via the web page here: Enter the port number and click the Check button. Besides, log-in the router and disable the firewall to ensure the router firewall doesn’t block the DDNS to be synchronous with external IP. Please let me know if these methods work.

  • Jenny Hu

    Hi Andrew, as the customized Reolink App is designed to manage all of Reolink security cameras, it cannot work with cameras of other brands. If you need to add a WiFi camera, Reolink can also offer you multiple options, such as the dual band WiFi security camera Reolink RLC-411WS, /product/rlc-411ws/ or the battery powered & solar powered wireless security camera Reolink Argus 2, /product/argus-2/. And please let us know if you need any further help with the camera selection.

  • Kate Walliss

    My son has moved out but would still like to view the squirrel assault course in the garden from his pc is this possible with reolink cameras. He does not have or want a smart phone?

    • Jenny Hu

      Hi Kate, of course, your son can view the live viewing of the garden from his pc with Reolink cameras (not the battery powered security cameras). And he doesn’t need to have a smart phone. If you need any recommendations to choose a most suitable product, please feel free to let us know and we’d love to offer some useful advice.

  • Jenny Hu

    Hi Darin, if you want to transmit the video data wirelessly and remotely from your camera to your smartphone, Internet is required to do the trick. Or if you really need to view remotely on your mobile smartphone for areas without Internet, you may consider adding a cellular security camera, like Reolink Go, /lp/reolink-go/, which operates on the 4G/3G cellular network like your phone (requires a SIM card), so you can stream the live feed anywhere & anytime you want. Hope this helps.

  • Bryan Reid

    OK… I have linked 4 barn POE cameras to a switch then via POA to my internet router. I would like to be able to view all the cameras on my computer monitor as well as watch it from a remote access line another computer or smartphone. But first from my computer which is linked to my internet router.

    • Jenny Hu

      Hi Bryan, do your security cameras support P2P technology? If yes, you can simply log into the camera app, enter the camera UID and password to view all the cameras on your computer monitor.

      • Bryan Reid

        Thank you very much on this. Wasn’t aware of P2P… so now I am and got them. A friend who gets up at 2:30 and 5:30 AM heading out to the barn during the Winter to check on calving will appreciate being able to view activity from the farmhouse. Thanks to you Jenny

        • Jenny Hu

          Hi, Bryan, you’re welcome! I’m so glad I could help 🙂

  • Phil Jones

    I am considering an LTE router for a remote property I have I will use this for Streaming, internet and Alexa, besides having 2 or 3 security cameras.. there are no other internet options. When I leave to go home, I want to be able to view the cameras. Is this possible? How would it work? At my home, I have ATT UVerse, DDNS address from , and use Blue Iris for my home cameras… I would ideally like to add the 2 remote cameras into my Blue Iris Console. Any advice is appreciated

    • Jenny Hu

      Hi, Phil, it’s not recommended to do so as the Internet connection would be unstable. If you want to remotely view your property without Internet, we suggest that you add a cellular security camera like Reolink Go for your remote site, /product/reolink-go/, and then you can view live feed from anywhere on your smart phone even without WiFi or Internet. Hope this helps.

  • Bret Mason

    I have my cameras set up great on my iPhone app and can view live or activity from motion activation. I am having trouble setting up remote viewing from my laptop. I have downloaded the reolink client and tried to add ip address as new device and have tried to enter ip address directly in URL box. Please advise me how to set up the laptop to view remotely from pc.

  • Jack Chen

    Why I can only view my ip camera with mobile data but not with wifi?

    • Jenny Hu

      Hi, Jack, please check if your currently using WiFi works well by visiting other websites. And you may switch to another WiFi network to see whether you can view IP cameras or not. Hope it helps.
