Need to know the best hardware application for web cam and microphone instant messaging through lap top hooked up to Digital laser projector with wireless mouse and keyboard. I have my Lap Top set up in my media room. I connect my Toshiba Sattelite 30 to a digital laser projector which projects upon a big screenthrough my 15 pin VGA default monitor connection. Resolution is great! S video connection sucked! I have a wireless keyboard and mouse for control over the display which is working great for games or surfing etc on the big screen. My question is I want the best web camming and audio available. Is there a wireless system suitable for viewing through instant messaging such as MSN messenger or AOL AIM? The ones I have researched are remote security systems and may not be suitable for what I am looking for. My other question is audio, should I use a web cam with microphone or should I use an external mic? Or is there again wireless mic which gives me total freedom? Any suggestions would be appreciated.
