How to choose a Webcam for
Skype
Nowadays,
Skype is extremely popular, and webcams are in huge demand. As video
communication may be required for various purposes, choose a webcam
depending on what you need from it.
The most important thing to consider is the
image sensor. That's what defines the quality and sharpness of the video taken
by the webcam. The sensor can be of one of two types, CCD or CMOS. CCD, which
takes high-quality video and introduces minimum video noise, is the best choice.
It's more costly than CMOS, but you might want to buy CCD anyway.
The second important factor is the definition of the webcam's lens.
There are
some options to choose from:
- 320 by 240 pixels.
That's the lowest definition. It's quite okay even for some business talk.
It probably will be good enough for a video conference.
- 640 by 480 pixels.
This moderate definition is available in many webcams. This definition will
do for recording a small video clip intended for uploading to YouTube or
sending to a friend.
- 1280 by 960 pixels.
This is the highest definition for a webcam. It's only available in the more
expensive devices. It provides the best image quality.
The third important parameter is the image
sensor's sensitivity. The higher the sensitivity, the better the video quality.
Even if you have the most expensive webcam, its low sensitivity may degrade the
video quality to that typical for the cheapest devices, and annoying video noise
may be present.
The fourth parameter to consider is the number
of frames taken per second. It's usually referred to as FPS. For high-quality
video, FPS must be 45 or higher.
Another important thing is which company made
the webcam. It's advisable to choose vendors that have a good reputation. If you
buy a webcam made by Genius, Creative, or Logitech, you most probably won't be
disappointed.
Besides, webcams may be equipped with a number
of additional features, such as autofocus, night mode, and so on. Actually, you
may not need all those bells and whistles if you only use your cam for
Skype. What is important is the availability of a built-in microphone -
unless you have an external mike or prefer using sign language!
