There is a sudden rush of software to make high-end digital cameras work as webcam in your computers. First Sony released a software that allows Sony GoPro action camera to be used as a webcam, then Fujifilm came up with a similar software and now Panasonic has updated their conventional Lumix Tether software to have the new feature which makes Lumix cameras available as a webcam. This new software is being called Lumix Tether for Streaming and as anyone can guess is targeted mainly at online live streamers who other wise buy expensive HD webcams for broadcasting over Twitch or Youtube or similar sites.
Needless to say that Lumix Tether for Streaming is designed to work with a select number of Panasonic digital cameras. At the present time, it works for the Panasonic Lumix models DC-S1R, DC-S1, DC-S1H, DC-GH5S, DC-G9, and DC-GH5. Perhaps in the future many more models will be supported. Panasonic suggests that you should upgrade the camera body firmware before using Lumix Tether for Streaming software.
Lumix Tether for Streaming is available for both Windows and macOS. For both platforms, you have to download and install the software followed by a reboot. Then you can connect your Lumix digital camera with your PC or Mac using any standard USB 3.0 cable for your camera.
The software displays a live mode window in which you can see what the camera is capturing through its lens. This live mode is very useful to see how you are looking in the camera before you start any live streaming. Along side the live mode window is a controls window that can be used to control how Lumix digital camera captures the images, whether auto focus is enabled, exposure level and many more settings.
