How web broadcasting works Webcams are those handy little cameras that attach to your PC and send images to a web page that can be viewed by others. This enables you to share daily life events with friends and family in other parts of the country or the world, or to arrange a video-conference with colleagues and maintain long distance relationships of all kinds. Of course the number of ways to use this technology is limited only by your imagination. But before you buy a webcam, it pays to understand a little about how the technology of broadcasting images over the Internet works. Of course, if you're a full bottle on this already, you can skip this section and go straight to browsing where you can compare products and suppliers, their specifications and prices. Webcams provide 'real time' images of people; places and events that can be viewed 'live' on a web page. The broadcasting end has a camera that captures the images, feeds them into a computer to an ISP and out to viewing pages across the Internet.

There are two different types of broadcast: streaming images, where the images are a constant stream downloaded in video format; or Java, where the images are captured at fixed time intervals and refreshed on the web pages at a rate fixed by the broadcaster. The Applications - What are you intending to broadcast, and to whom? There is a wide range of uses of webcam technology. Some examples include personal 'Big Brother' style diaries, sharing of family events, workplace security, video conferencing, virtual tourism, road traffic management, weather watching, event broadcast and a host of others. Before you make a choice about any webcam equipment, it helps to decide exactly how you want to use the technology, in other words, what you are intending to broadcast. This decision will impact upon the type of camera you use, and how you use it. A second consideration is, who will be viewing your content? What level of quality is expected? This will help determine the type of camera you use, the software involved and your Internet connection. Of course, your Internet connection may be a limitation on how much you can do. The requirements for video conferencing are different from the requirements of workplace security, which are different again from the requirements of sharing a family event.

The physical components There are a number of physical components required to make web cam technology work. At the top of the list is the camera itself. Then, depending on the type of camera you use and the way in which you want to deliver the content to the Internet, you may need to incorporate video capture hardware in your computer. Some software is required to help you process the data, and Internet connection is required and a web page into which the data is fed. CAMERA CHOICES Your choice of camera depends somewhat on what you are intending to show. If you need to reach a large public audience yo may want good quality camcorder or megapixel camera that captures high quality images. If it's just for seeing who's at your front door or keeping an eye on the kids in their playroom, then it may not need to present high quality images. If you are intending to use it outdoors, it will need to be weather proof and you may need to consider sun and UV protection. Available power supply and any robotic requirements for camera movement and focus are extra considerations.

Dedicated webcams The most basic webcams connect to a PC using a simple USB connection. A wide range of cameras with accompanying software at a range of prices is available for this type of application. Dedicated webcams are simple to install and easy to use, but come with limitations that affect the quality of the images, such as low number of frames per second (refresh rates) and resolution (pixels per inch). Camcorders and security cameras Higher quality images and more camera control come from using camcorder and security cameras. To use these devices you will need to add a video capture card to your PC.
