Headset A headset can be a very useful device during a video conference or webinar. Headsets are the perfect solution to echoes or problems with your computer microphone.
Webcam One of the greatest features of video conferencing is the the video. It’s really incredible to chat face-to-face with someone on the other side of the world. To do so, you need a webcam. Most new computers come with a webcam. If this is true for you, you are good to go! If not, you can purchase a webcam. Some webcams even come with a built in microphone, so you may not need a headset. Also, when you look for a webcam, make sure that it is compatible with your computer.
Microphone Most modern laptops and desktops have microphones. However, if you are going to buy an external microphone, make sure you know what can plug into your computer. Most are compatible with USB microphones.
