Need some help in purchasing a web conferencing system for a room that is 20X25 foot. Usually there would be 5-10 people in the conference. Right now they have a laptop and plug in a HDMI cable to a 50 inch TV and use that for audio and then use the mic on the laptop. They have a cheap webcam on top of the TV for video. I want a camera that would plug into the laptop and then be able to have an external mic plugged into the camera or the laptop. My budget is $600
