Are you beginner? I believe that this webcam is proper for you. I recommend Logitech series QuickCam Connect. The design is standard. It has a round head and clip which can be used in LCD monitor or CRT. On the webcam  head, there is an integrated microphone for chatting. It is made from plastic, so you can carry it whereever you want easily.

It is so practical and easy to install. Therefore, beginner customers prefer using it. After the easy installation, you are able to do video chats.
The quality of the image is displayed as good as VGA quality. It also can be interpolated till 1280×960 pixels. You  also are able to record still and moving images. The moving sensor is standard, while the picture movement is slower than the original.

With Logitech QuickCam Connect, a video chat activity becomes easier. Moreover, Logitech offers enjoyable software applications.
