Here at Newegg, we offer a wide variety of webcams that vary in function and level of sophistication. The most basic webcams are intended for internet chat use and give viewers a good picture of the person sitting at the computer. High-level webcams, on the other hand, produce fluid streaming video and can be used for business conferences, surveillance, and home security.
One of the most telling specifications of any webcam is the frame rate. This measures how many frames the camera captures every second. When a camera records just one frame per second (fps), the video appears very choppy. You will see very little correspondence between the person's mouth and the words he or she is speaking. A webcam with a frame rate of 30 fps, on the other hand, will produce video almost as fluid as a television broadcast.
Another important measurement is effective pixels. The more effective pixels your web cam has, the clearer the image will be. The most basic webcams produce good images, but viewers may not be able to discern certain details. Features that should appear curved may look rectangular. 1.3 MP or more of effective pixels is ideal however lower amounts of pixels will work for most general purposes.
