THE WEBCAM
The webcam is a unique device for entering visual
data into the computer. It can capture videos as well as still
pictures, depending on the program you use. Your job is to select the
camera that meets your
specifications and satisfies the functions which you
will use it for.
The most common use for the quickcam is video
phone calls, where you communicate with a friend, family
member, and others using
both audio and video. This allows you to talk and see the person you
are talking to. Sometimes this is done with a phone service and other
times it is done using instant messaging.
Another use for the video camera is to create a
video file and attach
it to an e-mail you send as a greeting. It might be a Happy Birthday
message or the Merry Christmas greeting you send to the entire family.
For more serious uses, you can use these
netcams for security
purposes by placing them strategically around the house. Then uploading
the video to a website, where you can watch remotely. Outside cameras
are also available with appropriate weather housings. Many preschools
use
these cameras so that parents can watch their children remotely while
at work.
Streaming
video is another use for these cameras. There are thousands of websites
displaying roads and auto traffic in real time from around the world.
Some are showing still frames every 30 seconds, while others are set
at different frame rates. There are cameras showing the Antarctic polar
expedition, and others showing the streets of Paris. While the videos
are endless, your opportunities are only limited by your imagination.
When selecting a webcam several considerations
come into play. Does it have a USB connector, or are you going to hook
it up to the local network? What is the cameras
resolution,
how many megapixels is it capable of capturing? Does it have autofocus,
can it refocus while tracking a moving target? What is the frame rate,
how many frames per second can it capture, is the motion smooth?
What is the lens quality, is it plastic, or is it glass, is it made by
a reputable manufacturer? Does it have a built in microphone, is this
important?
Now that you have an idea of some of the
questions, you can review the various cameras from your favorite
online computer store and make a decision
based on your needs and budget.
