Keep in mind that you still have to provide the hardware (video, audio, etc.) to capture the meeting and you'll need someone who knows how to put the video online. You'll also need someone to man the camera during the meeting (unless you have one camera that shows all of the officials and public commenters at the same time).
Solution: Our system includes the hardware and the software automatically switches to the camera that is facing the person(s) who are talking. And it's included in the ad-based model, which makes it essentially free for local governments (who are smaller than counties) to capture and stream their meeting videos.
