When I connect to WebCam Monitor giving the PC's IP and port number, I am not able to see any video or hear audio. What could be the problem?

First, make sure that you start streaming by pointing to the Tools menu and clicking Start Streaming. For streaming to work correctly, you must select a profile that streams videos at a bitrate less than the available bandwidth. For example, if you have a 56Kbps internet connection then a profile that streams videos at less than 56Kbps must be selected. You may also choose to stream only video (without audio) to save bandwidth required to stream audio. Refer to WebCam Monitor's help file for details on choosing an appropriate profile for streaming and for streaming only video or audio.
