If you don’t already have a laptop with a built-in webcam, or if the one on your laptop isn’t very good, you may need to get a separate webcam. Perhaps it’s to be able to reveal your face at work or school. Perhaps it’s for speaking with pals or for side ventures such as live streaming or filming yourself.
However, if you do not wish to acquire a webcam, there are various alternatives. You can get clever with your phone (for little or no cost) by utilising an app that tricks your computer into believing it’s a webcam. Alternatively, you could connect a high-priced DSLR or mirrorless camera to your computer and use it as a webcam – a pretty nice one, at that.
