Controlling Multiple PTZ Cameras in Scenes
Posted on Tuesday, February 23, 2021

Feb. 23, 2021 - Controlling multiple cameras at the same time used to take a crew of camera operators. Today there are a variety of ways to control multiple robotic (PTZ) cameras with a single click of a button. Controlling multiple PTZ cameras at the same time is ideal for "scene changes" where you would like some or all of your PTZ cameras to move to a new location at the same time.

In this blog post and video, you will learn how to control multiple PTZ cameras simultaneously using software and hardware solutions. A great free solution you will learn about is called OBS or Open Broadcaster Software. A paid solution that can be used to control multiple PTZ cameras at the same time is called vMix. Finally, we will look at a hardware solution from PTZOptics called the SuperJoy.

Why control multiple PTZ cameras at the same time?

More and more, video producers are also becoming camera operators. With the advent of remotely controlled PTZ cameras, a single video production person can also operate PTZ cameras with the click of a button. In many scenarios, video producers are operating two or three PTZ cameras at the same time using a video production software like OBS, Wirecast, vMix, Livestream Studio or the Tricaster. Many video production software solutions have integrated PTZ cameras controls for PTZOptics cameras which allow the software on a Mac or PC computer to connect to PTZ cameras over the local area network.

In most cases today, video production software operators are able to quickly take control of a robotic camera and move the camera's position directly through the live streaming software they are using. This is ideal during a live production, because a production operator can simply make a few clicks, zoom in a camera, check the focus and then transition to the camera taking the video live.

Another popular way to control multiple PTZ cameras is to have a hardware joystick for the video production operator to use. Hardware joysticks are popular because a team of two can split up the tasks between live video switching and camera operation. Whether you are using hardware or software for PTZ camera controls, it's nice to be able to move multiple PTZ cameras at the same time with the click of a button.

How to control multiple PTZ cameras in OBS at the same time

Using OBS you can control PTZOptics cameras in a couple of different ways. The most popular way is to install the free PTZOptics OBS plugin which adds some great robotic camera control features to OBS. Once installed, you can open up the plugin and control up to 8 cameras. The plugin even create specific hotkeys for calling PTZ presets and it adds the ability to control cameras with an XBox joystick. There is another way to control PTZOptics cameras with OBS called a "Dockable" interface using HTML codes available from PTZOptics. The HTML files can be used with the "Docks" feature of OBS to dock a PTZ camera controller directly into the OBS interface.

The third way to control PTZOptics cameras with OBS involves using HTTP commands. A document reviewing all of the HTTP commands for PTZOptics cameras can be found at the PTZOptics downloads page. These commands can be entered into OBS using the "Browser Source" input and they can be used to call a PTZ camera preset for example. In this way, you can enter multiple HTTP commands into OBS using multiple browser sources in the same scene to control various cameras. 

Pro Tip: Set up each camera in your network with sequential static IP addresses. In this way, you can easily input HTTP commands into OBS for this purpose. 

Using OBS to control multiple cameras at the same time simple involves a scene that is setup with multiple browser sources with HTTP commands. Remember to select "Refresh when active" to ensure OBS issues the HTTP commands everytime that you select the scene in OBS. 

Pro Tip: You can issue other HTTP commands besides camera presets as well. Check out the full list of HTTP commands in the PTZOptics documentation to learn more.

How to control multiple PTZ cameras with vMix

You can control multiple PTZ cameras with vMix using the Pro or 4K versions of the software. In order to take control over PTZ cameras inside of vMix you will need to know your PTZ camera's IP address and be on the same local area network as the cameras. If you do not know your camera's IP address, you will need to follow the instructions in the cameras set up video. Once you know your camera's IP address, you can simply enter it into vMix to gain PTZ camera control. 

Select PTZOptics as the camera type, enter the IP address and click connect. You can use the Pan, Tilt and Zoom controls to start moving your camera around the room. As you are controlling the camera, notice the speed options available for manual pan/tilt and preset pan/tilt. These are the controls you can use to tell vMix the speed at which you want the camera to move in a manual setting and during presets. 

In order to control multiple PTZ camera movements with vMix, you will need to start by creating PTZ presets. Once connected to a PTZ camera with vMix, you are able to create presets inside of vMix using the "Create Input at this Position" button. When you click this button, vMix will create an input with a thumbnail image of the camera's current location. When you bring this input into the vMix Preview window, vMix will recall that PTZ preset and move the camera. In this way, you can move your PTZOptics camera around your space and create multiple PTZ presets. Each preset gets a nice little PTZ input inside of vMix for easy recall. 

You can repeat the process above with each PTZ camera that you would like to use. Once done, you should organize the PTZ cameras you would like to be able to move with a single click. From here you can use the vMix Multi View feature available in the input settings of any input. Choose the input that you would like to use to trigger all the PTZ cameras. You can then add each PTZ camera input to the Multi View as you build a single input with multiple inputs attached. In this area, you can uncheck each PTZ input making it so the PTZ positions will be recalled but not overlaid on top of each other. Once done, you can transition to this vMix input and call multiple presets at once. You can do this for multiple scenes in your area and quickly call multiple PTZ presets at the exact same time with a single click. 

Pro Tip: If you are using multiple PTZ cameras with vMix, make sure to use a good graphics card. If you have an NVIDIA graphics card make sure to add vMix as a default application in the "NVIDIA Control Panel." Once you do this, double check in the vMix settings that you have your graphics card enabled. 

How to control multiple PTZ cameras at once with a joystick

PTZOptics has a new product called the PTZOptics SuperJoy. This joystick controller has a new feature called the "SuperPreset" which allows you to use a custom joystick button to control multiple PTZ cameras. The PTZOptics SuperJoy features four custom buttons that you can set up to do all sorts of video related tasks. For example, you can set up a custom SuperJoy button to turn on IP connected lighting in a studio setting. You can control pretty much anything that accepts a TCP/UDP, or HTTP command. Luckily, PTZOptics cameras have been designed to work with this joystick and the engineers have already setup the "SuperPreset" to control up to 6 cameras at once.
