A:AnswerHello Patsy. The C920S does not have any internal memory in the camera, so you will have to use a computer program to record the video. We offer free software for you to download called Logitech Capture. With Capture, you can adjust some of the settings as well as record your video and take photos. You can find Capture here: https://www.logitech.com/en-us/product/capture
A:AnswerYes, you could mount the C920S to a wall or surface if you would like but Logitech does not provide or sell anything to be able to mount the C920S.
A:AnswerYes, the C920S will work for streaming on Twitch. Make sure once you have the webcam plugged in to allow the webcam to be used for broadcasting in settings.
A:AnswerDepending on what application that you're using the C920s with, you should be able to choose what microphone you use. Many of these applications---for example Zoom---automatically will choose your Blue Ice microphone. Simply check the settings before using the application. - Richard from Logitech
A:AnswerHey there! You're correct, this camera includes a built in microphone and camera, however it does not include a speaker. You'll have to attach a separate speaker system or a headset.
