V4K requires software to be installed on your computer or laptop in order to be turned on. We recommend you download and install our software, Visualizer. It is completely free to download and use. You can find download and find more information about Visualizer here: https://www.ipevo.com/ipevo_visualizer
You can also use any third-party software that has access to UVC cameras, such as Skype, FaceTime, Microsoft Camera and OBS.
Once your software of choice is opened and your V4K plugged into a USB port, you will need to select the camera in your software's respective 'select device' menu. In Visualizer, it is located on the top of the left toolbar. Click the camera icon and you can select V4K under the 'Select Camera' drop-down menu.
