You can set up your phone (or DSLR) as a webcam in a pinch, no need to purchase new hardware. I recently upgraded to a gaming laptop with no camera at all, and for a moment thought my remote working life would be burdened by expensive and clunky extra hardware to avoid seeming ineptly suited to working from home. Instead it's only burdened by awkward phone placement, but the image quality is much better than before.
