Another option that's a little higher end is to use a dedicated video production rig, and feed that into your computer (or use the rig's direct integrations). Something like a Tricaster (https://www.newtek.com/tricaster/), which is very popular for live event video production.

The more complex the setup, though, the more likely you'd need additional people working the controls. (But also, the more flexibility and conveniences you get).

This is how I use OBS as well. I use a Tricaster Mini, and it has the ability to do a live stream of its output as a feature. However, it taxes this little computer to such an extent that the external power supply gets incredibly hot (too hot to touch). I now use OBS on a laptop to create the stream relieving the Tricaster of that duty. The Tricast power supply doesn't even get warm now.
