Webcam:

• A webcam is a video camera which feeds its images in real time to a computer or computer network, often via USB, ethernet or Wi-Fi.
• Their most popular use is the establishment of video links, permitting computers to act as videophones or videoconference stations. This common use as a camera for the web gives the webcam its name. Other popular uses include security surveillance and computer vision.
• Webcams are known for their low manufacturing costs and flexibility, making them the lowest cost form of videotelephony. They have also become the source of security and privacy issues, as some inbuilt webcams can be remotely activated via spyware.

Video Calling and Conferencing:

• As webcam capabilities have been added to instant messaging, text chat services such as AOL Instant Messenger, one-to-one live video communication over the Internet has now reached millions of mainstream PC users worldwide. Improved video quality has helped webcams encroach on traditional video conferencing systems. New features such as automatic lighting controls, real-time enhancements (retouching, wrinkle smoothing and vertical stretch), automatic face tracking and autofocus assist users by providing substantial ease-of-use, further increasing the popularity of webcams.
• Webcam features and performance can vary by program, computer operating system, and also by the computer's processor capabilities. For example, 'high-quality video' is principally available to users of certain webcams if their computers have dual-core processors meeting certain specifications. Video calling support has also been added to several popular instant messaging programs.
• Some online video broadcasting sites have taken advantage of this technology to create Internet television programs centered around two (or more) people "diavlogging" with each other from different locations. Among others, BloggingHeads.tv uses this technology to enable conversations between prominent journalists, scientists, bloggers, and philosophers.

Technology:

• Webcams typically include a lens, an image sensor, and some support electronics. Various lenses are available, the most common in consumer-grade webcams being a plastic lens that can be screwed in and out to set the camera's focus. Fixed focus lenses, which have no provision for adjustment, are also available. As a camera system's depth of field is greater for small imager formats and is greater for lenses with a large f-number (small aperture), the systems used in webcams have sufficiently large depth of field that the use of a fixed focus lens does not impact image sharpness much. Image sensors can be CMOS or CCD, the former being dominant for low-cost cameras, but CCD cameras do not necessarily outperform CMOS-based cameras in the low cost price range. Most consumer webcams are capable of providing VGA-resolution video at a frame rate of 30 frames per second. Many newer devices can produce video in multi-megapixel resolutions, and a few can run at high frame rates such as the PlayStation Eye, which can produce 320×240 video at 120 frames per second.
• Support electronics are present to read the image from the sensor and transmit it to the host computer. The camera pictured to the right, for example, uses a Sonix SN9C101 to transmit its image over USB. Some cameras, such as mobile phone cameras, use a CMOS sensor with supporting electronics "on die", i.e. the sensor and the support electronics are built on a single silicon chip to save space and manufacturing costs. Most webcams feature built-in microphones to make video calling and videoconferencing more convenient.
• The USB video device class (UVC) specification allows for interconnectivity of webcams to computers even without proprietary drivers installed. Windows XP SP2, Linux[7] and Mac OS X (since October 2005) have UVC drivers built in and do not require extra drivers, although they are often installed in order to add additional features.

How to Install a Webcam:

• Read the installation instructions completely before attempting to install the camera. Although this may seem tedious and unnecessary, it can save time and headaches in the long run.
• Back up the computer's hard drive just to be safe. This will allow for a speedy recovery should the installation mess up the computer.
• Install the webcam software. Before deciding to install the disc that came with the camera, check the Internet for an updated version of the software and download that if available.
• Plug in the webcam. The software should give a prompt at the appropriate time. Cameras are usually installed with a USB cable. If installed correctly, the computer will acknowledge so by popping up a message saying it can see the new device.
• Download an instant message program if using the web camera for chatting. Some free IM download programs include Yahoo Messenger, AOL Instant Messenger and Apple iChat.

How to Record Video From Your Webcam:

• Want to record video from your webcam and save it as a movie? This works with any webcam and any webcam capture program
• Start by loading your webcam and making sure it is detected by your computer properly. You can verify this by using a webcam test website or program
• Now you must choose a Free Webcam Recorder that will capture your webcam video input and save it as a movie file (AVI, MPEG, MOV, etc.)! You can find these on Webcam Recording Software websites
• You can use the Webcam Video Recorder software to capture your webcam video or other webcams that you want to save. For example, if you are on a webcam chat site, you may record their webcam with your software
• Use your favorite webcam video, and click 'Capture'! You've got your software loaded, capturing, and now all you have left to do is adjust your quality settings. It is highly suggested that you use a setting
• somewhere in the middle (around 40-60) for best results
