Understanding RTMP Cameras: How to Setup an IP Camera for RTMP Streaming [Updated for 2024]

Creating live streams and video content of any form has two primary sides. The first is your content, and the second is all the hardware and software that makes broadcasting your message possible. 

Many technologies and innovations strive to make the latter easier for broadcasters around the globe. Today, we’ll discuss IP cameras and RTMP streaming. 

IP cameras, also called network cameras, have recently replaced many other types of cameras and video recording systems. Analog cameras, CCTV surveillance cameras, and live-streaming webcams are just a few. Part of this recent upsurge in the popularity of IP camera live streaming is because they are inexpensive, packed with features, trustworthy, and secure. 

There’s another reason network camera live streaming is gaining momentum. They are easy to set up and operate. They don’t require wiring or computer systems. An IP streaming camera has an encoder, meaning you need less hardware and software to get your live streams out.

IP cameras have many advantages that make them popular among broadcasters for live streaming. The most significant advantage is that they provide greater control and security. 

RTMP technology is what makes streaming with this type of camera setup possible.

Considering the increasing popularity of IP cameras for live streaming, we’re going to take a closer look at how this type of RTMP camera works. We will look at how to use it to live stream on an online video platform with RTMP ingest. Specifically, we will cover how to successfully stream from a private network using the CamStreamer app with the Axis Camera. Then we will cover how to stream with non-Axis IP cameras successfully.

This blog will look at IP network cameras and where you can use them. We’ll also discuss how RTMP streaming works and compare different software and applications that work well together for IP camera streaming and RTMP ingest. Our goal is to equip you with the information you need to stream on your own private network.

What is an IP Camera?

An internet protocol (IP) camera is a video camera with a built-in RTMP video encoder, its own IP address, and often considerable intelligence. The camera’s IP address works just like the one on your laptop. An IP camera may sometimes have a built-in RTMP video encoder, but not all the time.

Axis Communications released the first IP camera in 1996. From that time on, Axis has been a leader in the field, continuously working on the technical development of its products. 

Looking at the product portfolio, we see that Axis cameras particularly excel when you use them outdoors. They’re highly resistant to impacts and weather fluctuations, including extreme temperatures, water, sunlight, and other adverse conditions.

Since IP streaming cameras are equipped with the technology mentioned above, they can communicate with other devices over the internet. That comes with many benefits.

Some of the advantages of this include:

• The IP camera’s video stream can be pulled from the camera by other devices with internet access
• The camera can be easily moved 
• The camera can leverage its intelligence (advanced video analytics) and autonomously track objects of interest
• It is easy to control the camera from a remote location.

IP Camera Streaming Quality

Wondering what quality video IP cameras can stream? Generally speaking, IP cameras are built to deliver a much higher quality video than analog cameras of most types.  You get 10 times more detail from a 5-megapixel IP camera than a 4-CIF analog camera. 

The video quality of most analog cameras maxes out at 704 x 480 pixels (4CIF). Comparatively, an IP streaming camera’s video quality can range anywhere from (720p/1080p) up to 5 megapixels (2560 x 1920). With this higher resolution of video IP cameras, you can:

• Zoom in and focus where needed 
• Get more detailed images and streams.
• Cover larger areas within the range of a single camera

IP Streaming Camera Use Cases

There are some use cases where IP cameras shine. IP network cameras for live streaming are especially suitable for 24/7 streams, broadcasts from poorly accessible locations, and shorter events that don’t require the physical presence of a cameraman, such as conferences, trade fairs, and lectures. 

Other use cases include

• Broadcasting nature: Because IP cameras don’t have to be tethered to multiple cables and can normally withstand a wide range of temperatures and external conditions, it’s a great solution for broadcasting nature. So whether that’s broadcasting thunderstorms, hurricanes, or a wildlife sanctuary, IP cam live streaming is a solution for natural environments. 
• Performances: Whether you’re looking to capture a concert or a theatrical performance, IP cameras can provide the dynamic angles that’ll engage your audience.
• Graduation: IP cameras don’t require a human to handle them physically. That makes IP stream cameras an excellent option for setting at an elevated height to capture great angles.
• Surveillance: Thanks to their ability to deliver higher quality streams, most organizations can benefit from integrating an IP network camera system for security purposes. Whether you’re looking to add security to a bank, a construction site, or your home, IP cameras can be a great option to provide that constant feed for peace of mind.
• Marketing: Businesses such as hotels, resorts, zoos, and aquariums can use IP cameras to showcase and market their beautiful surroundings.

Besides quality based on years of accumulated expertise, Axis cameras have another unique advantage compared to some other IP cameras– thanks to their open platform, called the Axis Camera Application Platform (ACAP), space has been created for developers to come up with applications designed to meet specific customer needs and use cases.

What Video Protocols Are Suitable for IP Camera Streaming?

An IP camera protocol is a set of guidelines that help regulate data sharing over the internet or a local network between cameras and other connected devices. It’s like a language that the IP camera uses to send a message.

The most widely used video streaming protocols for traffic cameras and other security cameras include the following:

• Real-Time Messaging Protocol or RTMP
• Real-Time Streaming Protocol or RTSP
• HTTP Live Streaming or HLS
• Web Real-Time Communication or WebRTC
• Common Media Application Format Streaming or CMAF/DASH

For IP camera streaming, the RTMP to HLS or RTSP to HLS configurations are typically the most popular. Most IP cameras use the RTSP for capturing by default while HLS is generally used for playback. 

RTSP is the most popular protocol for IP camera streaming and is popular amongst surveillance and traffic cameras.

However, this post focuses on IP streaming with RTMP ingest.

How Does RTMP Streaming Work?

Traditionally, RTMP streaming refers to delivering video content to Flash video players. However, in the context of RTMP cameras with IP and most modern live streaming technology, RTMP is responsible for ingesting video feeds.

RTMP ingest transports video files from the encoder to an online video platform. For this process to work, each component must have RTMP compatibility. 

In the case of IP cam live-streaming, both RTSP and RTMP come into play. A video signal provided by an image chip inside a network camera must first be encoded into the H.264 video format. Then, you can send it over the Internet. 

In principle, all network cameras pack encoded video into RTSP (Real-Time Streaming Protocol) that is used to send such a video stream over the network. RTSP is a so-called “pull” type of protocol, meaning you need to connect to an RTMP-enabled camera via its public IP address and forwarded port and pull the video from it.

This technique is okay for the video management systems it was designed for, but online video streaming platforms, such as Dacast, need something else. They need an IP camera with a built-in video RTMP encoder to “push” the video stream to them. RTMP pulls the RTSP video stream from a network camera and repacks it into RTMP. 

What is the Difference Between RTMP and RTSP CCTV?

RTMP (Real-Time Messaging Protocol) and RTSP (Real-Time Streaming Protocol) are widely used for video streaming. However, they serve different purposes, particularly when it comes to CCTV systems.

RTMP is commonly used for live video broadcasting over the internet. When using an RTMP IP camera, the video feed is streamed directly to platforms such as YouTube, Twitch, and Facebook Live. An RTMP streaming camera provides smooth, low-latency video. This makes it ideal for applications requiring real-time interaction. In terms of security, RTMPS cameras use an encrypted version of RTMP for safer transmissions. CCTV RTMP is useful for live streaming, but it’s more suited to web platforms than traditional CVTV.

On the other hand, RTSMP is designed for local streaming over a network. It’s typically used in surveillance systems. CCTV RTSP streams work the best monitoring on closed networks. Unlike RTMP, RTSP is tailored for direct-to-device streaming without the need for web-based platforms. This makes CCTV RTSP a better choice for monitoring and recording within internal security infrastructures.

So, when comparing RTMP vs RTSP CCTV, RTMP excels in online broadcasting while RTSP is better suited for traditional CCTV setups. Some cameras such as Axis RTMP cameras offer both protocols, providing great flexibility. Choosing an IP camera with RTMP support or RTSP capabilities depends on whether your focus is on public streaming or secure, localized surveillance.

RTMP Webcams and FFmpeg Live Streaming

RTMP webcams are ideal for live streaming video to platforms such as YouTube, Twitch, and Facebook Live. These cameras utilize the RTMP (Real-Time Messaging Protocol) to transmit video data over the internet in real time. They provide low-latency, high-quality video. In particular, they’re useful for content creators, educators, and businesses wanting to engage audiences through live video.

To set up a live stream IP camera using RTMP, you can use FFmpeg, a powerful open-source tool for video and audio processing. By using FFmpeg webcam to RTMP, you can easily broadcast live streams from your webcam to any streaming platform that supports RTMP. This setup is commonly used for IP camera streaming services and can be implemented on both Linux and MacOS.

Here’s how to broadcast a live stream using FFmpeg:

1. Install FFmpeg on your Linux or MacOS system.
2. Connect your webcam or IP camera to your computer.
3. Use the following command to stream live to an RTMP server:

   “`

   ffmpeg -f v4l2 -i /dev/video0 -f flv rtmp://your-streaming-server-url/live

   “`

This command captures video from your webcam and streams it to your IP camera streaming server using RTMP.

So, when comparing RTMP vs RTMPS cameras, RTMPS adds an extra layer of security through encryption, which is essential for truly secure streaming.

There are various IP camera streaming protocols available, such as RTSP, HTTP, and HLS. However, RTMP remains popular for public live streaming because of its compatibility with most platforms. When choosing the best IP camera for broadcasting, we recommend opting for a camera with RTMP support for easy integration and streaming platforms.

Overall, RTMP webcams are a versatile and efficient choice for anyone looking to broadcast live personally or professionally.

Using the CamStreamer App for Live Streaming

Running directly onboard the IP camera, the CamStreamer application is a simple piece of ACAP software. Its primary function is to repackage the RTSP camera’s video stream into the RTMP format, which the online video platform can then easily work with. 

That brings several advantages since broadcasters using this technology don’t need a computer or a public IP address. They also don’t need to set up port forwarding. 

With a few simple clicks, you’ve got the full potential of the IP camera at your fingertips. The RTMP camera is a computer in and of itself, so it can connect to the online video platform without any additional hardware, excess cables, processors, and so on. 

Thanks to the intuitive settings and no extra costs, a few seconds is all it takes to get a live broadcast up and running.

Setting Up the Axis IP Camera with CamStreamer 

The first step to setting up the Axis IP Camera with Cam Streamer is downloading the CamStreamer app, which you can find on their website. 

Next, choose the right installation package according to your camera type, and enter your camera’s IP in your web browser. Once this is set up, you can connect to your RTMP-enabled camera. 

In the CamStreamer setup, all you need to do is to choose the desired streaming platform. You can choose Dacast, as it’s one of the preset streaming platforms.

From there, simply enter your RTMP stream details from your Dacast account. Since Dacast is a preset streaming platform from CamStreamer, the RTMP connection will be made automatically, which saves you another step. 

Once you’ve completed these steps, you’re ready to stream.

How to Setup Other IP Cameras for RTMP Streaming

Now that we have covered how to set up an IP camera live stream as an Axis IP camera for RTMP live streaming, it’s worth it to repeat that not all IP cameras come with a built-in application or brand app (e.g., CamStreamer) that can turn an RTSP camera’s stream into an RTMP stream. In other words, many IP cameras require extra hardware or software to live stream on a platform like Dacast or YouTube.

In the next part of this blog, we’ll cover how to set up an IP camera for RTMP streaming in a more general sense (when you don’t have an Axis IP camera specifically).

Step 1: Choose WiFi vs. Ethernet  

The first step of setting up an IP camera for streaming is connecting to the network, which calls for you to choose between WiFi or ethernet for live streaming. Both have unique advantages and disadvantages depending on the use case you’re after.

For starters, ethernet cables allow for a higher quality image than WiFi because ethernet cables can handle more data. It’s also more dependable than WiFi because you’re connected directly to the network rather than wirelessly. Another advantage of ethernet cables for IP cameras is that they support Power over Ethernet (PoE), meaning they can last indefinitely without needing someone to replace the battery.

The downside of ethernet cables is that they’re tethered to cords, so you don’t have as much flexibility to put the IP camera wherever. Since WiFI requires no cables, you can place IP cameras anywhere as long as they can connect to the internet wirelessly.

So when choosing between the two options, consider the importance of flexibility, video quality, and stream length.

Step 2: Choosing an Encoder 

The combination of CamStreamer as an application and Dacast as a streaming solution can deliver great results. Using this combination, you can easily produce professional-grade content. But as mentioned, not every IP camera uses CamStreamer because this app only works exclusively with AXIS IP cameras.

A little technical background and refresher: The default protocol for IP cameras is RTSP, which we spoke about earlier. RTSP is designed for network use, meaning it was originally intended to stream directly to a few end-user devices. In other words, it’s unsuitable for live streaming to hundreds or thousands of nationwide viewers.

To add to that, many streaming services don’t support RTSP Ingest. But every streaming service supports RTMP Ingest, meaning you need to add a middle step when streaming directly from an IP camera to a destination like YouTube or your website. For this reason, streaming with an IP camera tends to be a bit more complex than streaming with other webcams.

With that said, to livestream with most IP cameras, you’ll need an encoder. (The exception is if the IP camera supports RTMP push, which you can find out by calling the support line of your camera brand).

An encoder converts the images captured on the IP camera and then transmits them into a readable form that a video hosting service like Dacast can use. CamStreamer serves the same purpose as an encoder but for Axis IP cameras.

Keep in mind that you can’t just use any encoder. The right encoder will depend on your IP camera and the video platform you use. If live streaming with an IP camera using Dacast, we recommend the Wirecast encoding software or OBS Studio software encoder, a free alternative to Wirecast.

Step 3: Choosing an Online Video Platform

When you want to use an IP camera for live streaming, you’ll need an online video platform most of the time. Now that you know you need an encoder for many IP cameras or an app like CamStreamer for Axis IP cameras, you’re ready to explore online video platforms.

Dacast includes all of the tools you need for a professional broadcasting experience. Our platform supports video monetization, video player customization, reliable security and video delivery, private video sharing, a powerful content management system, and more.

Unlike YouTube and Facebook, which as streaming platforms, don’t allow audiences to be divided up for more efficient marketing, Dacast offers all the tools needed to make streams effective, attractive, and profitable.

Of course, Dacast is one of many online video platforms on the market. Feel free to check out our online video platform comparison post to see how Dacast stacks up to some of the other top options on the market.

Step 4: Set Up and Configure Encoder

For simplicity, we’ll cover this step as if you’ve chosen OBS Studio, a free and popular software encoder. Other encoders have similar steps. Here are the rough steps you’d follow:

1. Open OBS Studio.
2. Find the “+” sign under the “Sources” section.
3. At this point, you’ll name your IP camera source (e.g., brand IP camera)
4. Generally, you’ll uncheck all the options available on this tab.
5. In the “Input” field, insert the RTSP URL. (Each type of camera has different URL formats, so if you get stuck here, your camera brand’s support team should be able to help.)
6. Click “OK,” and your live feed should be ready. Right-click the video to play around with the video size.
7. Go to the OBS Studio settings menu and click on the “Stream” tab
8. Enter the relevant information depending on what service you’re using. If you’re using Dacast, check out our OBS Studio guide for more.

That’s it! You should now be ready to live stream from an IP camera.

Integrated Graphics with CamOverlay

Now that we’ve covered how to set up another IP camera for streaming let’s talk about ways you can improve the videos on Axis cameras.

CamOverlay is an app that works with the CamStreamer application to help broadcasters add their own graphics to a stream. 

This tool is useful for adding additional information to the screen to increase the viewers’ experience. CamOverlay supports multiple sources, which gives broadcasters added flexibility on what they can do with their live streams.

Just like CamStreamer, the setup of CamOverlay is effortless. There are preset templates to choose from, or you can create your very own graphics. Both options give you control over your stream’s appearance, timing, and position.

Now that we’ve covered the “whys” of using CamOverly, let’s look at how to use this app. Here are three steps for setting up CamOverlay:

1. Install the CamOverlay application on your RTMP camera
2. Select one of the preset templates or generate your own graphics
3. The application then inserts the graphics directly into the video stream

That’s all there is to it. The types of information added to live broadcasts can vary. The most common uses of CamOverlay are for displaying advertisements, presenting partners and sponsors, and for providing information that’s useful to viewers.

Using CamOverlay to Deliver Your Message Successfully

Unlike other methods of adding your own graphics to a live broadcast, CamOverlay has two specific advantages that result from the fact that displayed graphics become part of the live stream.

The first is that the graphics are immune to ad blockers, and the second is that there are no compatibility issues with different types of players.

The graphics are simply a part of the live stream, so you don’t have to worry about things like keeping them in focus, the way they look in various types of browsers, administration, timing, etc. 

The biggest benefit to this solution (and this isn’t true only of CamOverlay but of overlay graphics in general) is that you can make simple streams more attractive with information that gives the broadcast a story, an idea, and some context. 

It works well, for example, in the live camera stream of the Prague skyline (pictured above). Besides weather data, the stream displays facts about the individual monuments the RTMP camera is focused on.

Thanks to CamOverlay, viewers get helpful information from a plain reality stream, in this case, regarding the history and beauty of the capital of the Czech Republic. You can also choose a different call-to-action (CTA) and get results based on marketing or other needs.

Benefits of an IP Camera

Compared to other webcams, IP cameras are much more versatile and flexible. Because they can connect over the internet, they don’t have to be close to the computer processing the image.

Another advantage of IP cameras, specifically PTZ (Pan-Tilt-Zoom) IP Cameras, is that you can reposition a camera or zoom in and out without a physical human being present. A person miles away can control many different IP cameras from one place. They don’t require a human to constantly monitor it either. That’s why it’s great for 24/7 use cases.

IP cameras today also use Power over Ethernet, meaning that they can stay charged indefinitely when connected to the wired network.

FAQs

1. How does IP camera streaming work?

An Internet Protocol (IP) camera has an RTMP video encoder as well as its Internet protocol just like a laptop. This enables the camera to communicate with other devices on the internet. 

As such, other cameras with internet access can pull a video stream from IP camera videos. 

2. Can security cameras be used for live streaming?

You can use security cameras for live streaming and it can be a cost-effective choice for video conferencing and remote surveillance. However, it depends on the features of the camera in question. 

Most current security cameras come with integrated web servers that can be accessed remotely through mobile applications and web browsers. As such, you can use these security cameras as webcams and broadcast their live footage over the internet. 

3. What protocol does an IP camera use for streaming?

For IP camera video streaming protocol, the most common streaming protocols for IP camera streaming are the RTMP and RTSP protocols. In general, all network cameras encode video footage into RTSP (Real-Time Streaming Protocol), which is used to broadcast such a video stream over the network. RTSP is a “pull” protocol, which means you must connect to an RTMP-enabled camera (with an optional RTMP camera app) using its public IP address and forwarded port and pulls video from it.

4. How do I host an IP camera?

You can host and broadcast IP cameras and make your feed accessible online by connecting your camera to a server. This way users can view your live stream remotely through your domain or a web address you provide.
