While it does not have a USB out to function as a webcam, it does however seem to have a composite video out (RCA cable). If you have a capture card, you can use it as a sort of "web cam" this way.

Burbble, could you please explain a little?

Connect further...control easier

With the ATEN CE624, you can now enjoy a high-quality visual experience powered by HDBaseT technology and the convenience of a single Cat6 cable to transmit uncompressed video with zero latency and multi-streaming for dual-view applications where remote access is required.

...but if you don't (have a capture card), it would be cheaper to purchase a real web cam.

On the camera, there should be a yellow "Video Out" that sends the image as an analog signal. If your computer has a video card that can receive this kind of analog video, then programs might be able to use it as a web cam (but there's no guarantee).

It's really not worth getting a new video card just for this. Web cams are far cheaper.

Ah, but a Nikon Coolpix 4300 is so much sharper than a typical webcam!  I had an Olympus 2020Z that I used that way, but the problem is the camera shuts down after it detects "no use" for a few minutes.  If you're really interested in a better camera for the web, and not just to use your camera for another purpose, take a look at www.smarthome.com.  They have dedicated security cameras that are sharp, as well as remote controlled.

I do already have a web cam, but as Callandor said I was hoping to get a much better picture using my Nikon. Thanks for the info folks.

As a capture card can run up to (and over) $100, and would not actually give you an explicit "web cam" capability, it would probably be more practical to purchase a camera specifically designed for this kind of function.

Also, realize that any video feed via USB will suffer, to some degree, from those blocky or blurry artifacts on the picture because it is being heavily compressed to be transmitted. There is no way to get a "clear" NTSC or PAL video signal through a USB connection.

Sorry, this probably wasn't the answer that you had hoped for... But thanks for the points :)

Hmm, that may have been a bit confusing... I was just trying to say in response to...

>> I was hoping to get a much better picture using my Nikon

...that it might not actually be possible to get a significantly better picture from a better camera, due to the nature of web cams.

If you are video conferencing with someone, there is also the consideration of the speed of the Internet connection being used. A slower connection will require heavier compression, which will reduce the size and quality of the images.
