I'd have a look at the Axis M1031-W IP Camera. The Camera supports H.264 which provides high-quality video at low bandwidth when compared to MJPEG and MPEG-4 cameras. There is also two-way audio which, from experience, works very well.
We think many ip camera can do this, such as Axis, Vivotek, D-Link ip camera etc, you can directly connect these device to router, and can view it's video on internet !
H264WebCam 3.5 can record video and audio stream from many network ip camera. Support motion detection,broadcast on internet.

Most cameras can do this if you want your webcast viewers to view jerky video and audio in an non cross-platform way!
If you want to use an IP camera for webcasting full framerate video and audio you're best to choose an Axis camera or video server (and use their video capture driver) and have a separate audio source (not synced).
If you want truly sync'd audio and video you're going to have to find another way to rebroadcast a single source audio/video stream from an IP camera with a/v sync like the Axis 207MW.
IP cameras are not (as yet) best suited to broadcast-like applications such as webcasting. They do an acceptable approximation though
All IP cameras are good to use, as there are Axis M1031-W, Panasonic BL-C131A which prevents Wireless interference as it is connected to the wireless Router or we can say wireless access point which should be placed in the center of any area that you are using for the best coverage, to avoid interference.
It should be mounted properly atleast 6 inches away from the wall.
i'm not sure why people are saying that ip cameras are not suitable for this situation. any mpg4 or h264 camera is usually just a container for video + audio so it should handle both just fine and in sync.
the main issue is the rebroadcasting of the video/audio. there are bandwidth considerations depending on how many connections there will be to the video and the setup of the camera.
you can quickly bog down a camera if you are broadcasting directly. that is why there are usually servers solutions used for serious live broadcasting.
you can look at some free ones like ustream or justin.tv for examples.
you can also typically use usb cams hooked up to your pc for this type of connection also.
