Many computers, particularly laptops, come equipped with built-in webcams. However, built-in webcams lack some of the features available in aftermarket models. The most obvious limitation of built-in cams is their fixed position. They can only look in the direction the computer is facing, and it is easier to rotate and reposition a small webcam as opposed to your entire computer. Aftermarket cams also offer increased resolution over most built-in models. Whatever your reason for wanting to use an external cam, such cameras are easy to install and use, even alongside a built-in webcam.
