WHAT IS A WEBCAM?

Simply put: a camera used on the

World Wide Web.

notebook (laptop) computers have a

web cam and microphone built-in.

A webcam can be used to:1) Take single pictures of the person in front of it.

2) Take video of the person in front of it.

3) Work with communication software such as

Skype, Yahoo Messenger, Windows Live

Messenger, AIM.

A webcam can be used to:4) See who’s at the front door.

5) Keeping an eye on the baby (or babysitter).

6) Security – checking your house when you’re

away.

THE WEBCAM FROM YOUR

SIDE OF THE LENSWhy else would you want to use a

webcam?

Most of us our visual. A webcam adds “life” to

conversations and, perhaps, allows us to see people

we care about but who live a great distance.

THE WEBCAM FROM YOUR

SIDE OF THE LENSAre there different qualities of

webcams?Yes! Webcams now come in HD (High Definition)

Pixel size is important as is frames per second

(30fps)

Those webcams with glass lens (rather than plastic)

give a better image

webcam for better quality and portability.
