The most basic type of webcam is a simple camera that can record video and images. Most webcams are designed to perch on the edge of a monitor or laptop screen, or sit on a flat surface like a desk. If you have modest needs and a tight budget, you can pick up a basic webcam for simple video calls.

Webcams come in a variety of types, designed for different needs and uses. When you're shopping for a webcam, make sure it's compatible with your system (e.g. some models only work with Windows PCs).

Webcams can be used for more than just simple video chats. It's easier than ever to post homemade videos on sites like YouTube, and a good webcam can spell the difference between a poor quality video and a high-resolution video that's a pleasure to watch.

Most laptops and some all-in-one desktop PCs have webcams built in, but if you need high-resolution image quality or extra features, you're better off getting a separate webcam. Browse Best Buy's wide selection of webcams and you'll find ones that can take your communication or content creation to a whole new level.
