Ask HN: What are startups using for conference room video conference setup?

Now that we are almost non-remote, I am trying fit a video conferencing solution for one of our conference rooms. Looks like it is expensive. - $2000 for hardware - $50/month for Zoom Rooms subscription Is there a cheaper way to do this? 10 person room. Need a good audio on the table. Tracking camera is optional. Can this be done using a Pi? Or an old laptop as hardware?
