Q
How much memory does C-it require?
A
Your computer will need at least 16 Mbytes of RAM in order to run C-it software. However, to
guarantee stable work with other open applications, the computer should have 32 or more
Mbytes of memory.
Q
Does C-it supports Windows NT?
A
The current version NT 4.0 doesn’t support USB. We will support C-it in NT5.0 when
Microsoft releases it.
Q
Is there a Macintosh Version?
A
No.
Q
Do I need any other devices to make my C-it Digital Video PC Camera work (capture card,
Microphone, etc.).
A
Your computer does not need a capture card of any kind. that's all taken care of by the C-it
Digital Video PC Camera. Of course, your computer will need a USB (Universal Serial Bus)
port to connect C-it Video Camera. Your computer should also be a multimedia PC with a CD-
ROM drive, sound card, speakers, and microphone.
Q
How do I install my C-it Digital Video PC Camera?
A
First, make sure that your computer has a USB slot and that USB support is enabled (check
BIOS settings). If everything is OK, you can install the software from C-it CD-ROM. When
software installation is complete, plug in C-it USB Camera, and wait until the plug and play
wizard completes the update configuration.
Q
My computer does not have MMX Technology. Will the C-it still work?
A
Yes, it will.
Q
What is MMX technology anyway?
A
Basically it's a series of enhancements to the Pentium processor specifically for improving
multimedia and communications. With MMX, the visual media on your computer will play
faster, smoother and appear more realistic.
Q
Is it compatible with my TV?
A
Normally no. The C-it Digital Video PC Camera is supposed to work with your desktop PC not
a TV. The only time it might work with a TV is when you are using a TV set as a big monitor
for your computer.
Q
Why isn't the picture more like a TV?
A
With the C-it Digital Video PC Camera you typically have two video windows: Local Video
and Remote Video. The Local Video window shows the video being captured by your camera.
You can expect good quality real-time video there. The Remote Video window shows the
person you are calling. The picture quality in this Remote Video window can be lower quality
for a number of reasons. The other person may have a low quality camera that does not produce
a good image. The other person's software may be compressing the image before transmitting it
through the phone line or the Internet. In some cases, the video signal is so tightly compressed
that errors are introduced (called "lossy" compression). In fact, to transfer 30 frames per second
QCIF (176x144) resolution video, the video phone system has to squeeze video by a ratio of
more than 600:1! For motion video, that much compression almost guarantees loosing a bit of
precision. Also, the decompressor on the other end may create accumulating errors by
reconstructing the image less accurately than normal. All these factors alone or together
introduce errors that affect the quality of picture you receive.
