Image sensors can be [[CMOS]] or [[Charge-coupled device|CCD]], the former being dominant for low-cost cameras, but CCD cameras do not necessarily outperform CMOS-based cameras in the low-price range. Most consumer webcams are capable of providing [[Video Graphics Array|VGA]]-resolution video at a [[frame rate]] of 30 frames per second. Many newer devices can produce video in multi-[[megapixel]] resolutions, and a few can run at high frame rates such as the [[PlayStation Eye]], which can produce [[Quarter VGA|320×240]] video at 120 frames per second.<ref>{{Cite web |url=https://www.cnet.com/reviews/samsung-700g7c-review/ |title=Cnet |access-date=2021-07-19 |archive-date=2021-07-14 |archive-url=https://web.archive.org/web/20210714184641/https://www.cnet.com/reviews/samsung-700g7c-review/ |url-status=live }}</ref> Most image sensors are sourced from [[Omnivision]] or [[Sony]].

As webcams evolved simultaneously with display technologies, USB interface speeds and broadband internet speeds, the resolution went up from gradually from 320×240, to 640×480, and some now even offer 1280×720 (aka [[720p]]) or 1920×1080 (aka [[1080p]]) resolution.<ref>{{cite web |title=How Much Resolution is Enough?
