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.
