Logitech Fluid Crystal™ Technology. It’s what makes a Logitech webcam better. It’s smoother video, sharper pictures, richer colors and clearer sound in real-world conditions. Logitech Vid™ HD is free, fast and easy for you and anyone you call. It sets up when you set up the webcam. Your loved ones will see you in lifelike color when you talk to them, or you can take photos to share later.
