Webcams help to remotely monitor a situation and help us gain a modicum of control of that situation. There are various webcams that are available in the market today made by companies like Logitech, Microsoft, Philips and Creative. They consist of essentially a digital camera that is connected to a computer. Most webcams now connect to a computer through a USB port and generally require a flat surface to function effectively. However many webcams today clip onto laptop computers like the Veo Mobile Connect Web camera, the Creative Webcam NX Ultra and Logitech QuickCam for Notebooks Pro. Along with the digital camera there is software which captures a frame from the digital camera component of the webcam at periodic intervals and then transfers this image to the viewing location. If you use your webcam for streaming video and chatting you would need one with a high frame rate. The frame rate indicates the number of pictures that the software can capture and transfer in a second and a high frame rate of say 30 frames per second is considered to be ideal for streaming video. In order for this frame rate to function effectively the web camera must be supported by a high speed broad band internet connection as well. |
The software can transmit this image over the internet using various broadcasting methods like turning the image into a JPEG file which is then uploaded onto a web server by using File Transfer Protocol. If you have your own web server and website then you already have a home for your images, if not many companies offer you a free place to load your images so that you don’t have to set up a web server or maintain a website.
Webcams are used in a wide variety of situations today like to transmit traffic conditions in the case of Trafficams, to monitor the weather in the case of WeatherCams and even in reality TV shows like the popular Big Brother reality show.
