These iChatAV (Version 2) pages are coloured Green and have the iChat 2 icon on them that was in use at the time, so you know where you are. The icon differs from Version 1 by having the camera logo added.

6 Video Preferences Picture
This is the iChat 2 Video Preferences. Last pic in this series.
This is where you check your Camera is producing a Picture and set the Input device (Microphone).
On Macs that have a LIne-In option and an Internal Mic you will get the Microphone Drop Down choice. The device chosen in here must match the choice made in System Preferences > Sound > Input tab. It will show the Line-In option even if you have nothing attached.
The External iSight camera will display in System Preferences > Sound as an Input device and here in iChat as a Microphone choice as it has internal microphones included. This may apply to you if your Camera has a microphone, although it may be listed as a USB device in the System Preferences.
My G4 tower has Line-In but no Internal Mic so I use an external USB mic.
The Bandwidth caps any Internet speed if not set at NONE. This can be adjusted on the fly during a chat and the results will be seen in the Connection Doctor if open. If you are on a very fast connection and you Buddy is not - it may pay to reduce your setting here to 500 or even as low as 200 - because with modern internet speeds it is possible to overwhelm a slower Buddy.
iChat will tend to use about 80% of what is set and as 100kbps is the practical every day lower limit for a Video chat it is not worth using that setting. You will get a failure message if iChat detects or falls below 50kbps (below Dial-up modem speeds).
If you are still at Quicktime 6 which came with Panther or have even updated to Quicktime 7 - the setting for the Connection speed (Quicktime 6) or Streaming speed (7) in System Preferences > Quicktime > Connection speed/Streaming tab also directly effects iChat as iChat reads the Automatic setting as a 0kbps and a similar miss-read of the top Intranet/LAN setting so setting it to 1.5Mbps / Intranet / LAN is best. Don't worry about any Cable or DSL reference as DSL speeds now outstrip these guide comments in Quicktime.
With external cameras that can be set to be On all the time you can set it so iChat will start up if the camera is On. It also works as a method to re-log in to AIM if the connection is lost. This setting remains in iChat 3 and 4 but does not work with Internal cameras although only iChat 4 specifies it works only with External cameras.
