Webcams fall into an ill-defined area between digital cameras and video camcorders.
Today, webcams have the ability to take both great quality pictures and to capture high-definition video.
Due to webcams falling in this grey area, there is no set standard for how to describe each webcam's capabilities.
One webcam may be listed as 2.0 megapixels and another as 1080p.
This is because at 1080p, the webcam and CPU have to process much more information than at 720p, thus slowing the frame rate down to 10FPS or lower, which in turn creates less fluid video.
