Webcam

A web camera (or webcam) is a real time camera whose images can be accessed using the World Wide Web, Instant messenger, or a PC video calling application. Generally, a digital camera delivers images to a web server, either continuously or at regular intervals.

A webcam is also the name of a class of video camera devices which connect directly to the PC for the purpose of video calling over the internet.

The first webcam was pointed at the Trojan room coffee pot in the computer science department of Cambridge University. This webcam is now defunct, as it was finally switched off on August 22 2001. The final image captured by the camera can still be viewed at the webcam s homepage [http://www.cl.cam.ac.uk/coffee/coffee.html].

As with many new technologies, webcams and webcam chat found their earliest commercial adoption and most aggressive technology advancement through use by the pornography industry.

The adult industry required live images and requested a Dutch developer to write a piece of software that could do this without using so called plugins . This led to the birth of the live streaming webcam , which is still available in various forms today.

Initially intended for personal Video teleconference, it was quickly realised that World Wide Web users enjoyed viewing images from cameras set up by others elsewhere in the world. While webcam refers to the technology generally, the Web part is often replaced with the Category of images the camera provides.

Today there are thousands of webcam that provide views into homes, offices and other buildings as well as providing panoramic views of cities (Metrocams) and the countryside. Images from satellites are frequently posted on the World Wide Web. Webcams are also used to monitor traffic with TraffiCams, the weather with WeatherCams and even volcanos with VolcanoCams.

As webcam capabilities have been added to instant messaging text chat services such as Yahoo Messenger, Google Talk, AOL Instant Messenger (AIM) and MSN Messenger, one-to-one live video communication over the internet has now reached millions of mainstream PC users worldwide.

Many companies have tried to jump on the live video bandwagon, most notably vdolive (an Israeli company), Spotlife (a Logitech daughter company) and many others, most of these have since failed.

In mid-January 2005 two easy to use Google string searching algorithms have been published in an on-line forum. These can find thousands of Panasonic- and Axis Communications-made high-end web cameras. Most of such cameras are running on default configuration, which does not require any password login or IP address verification, thus once again generating public controversy over webcam privacy issues.
