As disc drives become less common, more webcam manufacturers provide the latest drivers online.
Place the webcam on a flat surface so that pictures and videos don't appear crooked or skewed.
Use a stack of books or a tripod to align the webcam to shoot video of something other than what's directly in front of the screen.
Depending on the style and model of the webcam, it may or may not have a convenient and adjustable clip to attach it to the monitor.
Use the clip to attach the webcam to the top of the monitor to record yourself looking at the screen.
Many times, hardware (including some webcams) doesn't have a disk with drivers.
