Do you need a camera or camcorder to record the computer screen?

Do you need a camera or camcorder to record the computer screen?

 

If you want to record every click of what you have been doing on computer, camera is not the only choice.

Because a camera or camcorder in front of your computer to record your screen is not practical with the following reasons:

1. It can not record the screen precisely.
2. The resulting video will be fuzzy.
3. The recording is not easy to edit.
4. The video file is too large for web sharing and transmission

Computer screen recorder is what you need.
You could use some screen software to record desktop screen to video, and save as avi, wmv, swf, flv format, which could be uploaded to Youtube and other blog or video sharing website immediately. Also, the record video file size is much less that the camera.
