Mileage varies between cameras, but one small warning to anyone considering this if they spend even a couple of hours a day in meetings with the camera on from time to time - the sensors in some DSLRs/mirrorless models can overheat while live streaming and your video will cut out.
Most of them were only specced to record up to 30 minute clips at a time in original guise and are passively cooled, so running for an hr or more can push the sensors beyond their original specifications etc. I've had this happen rarely with some m43 cameras I use as webcams via an HDMI capture card. There's a ton of youtube videos on this topic with all sorts of homemade cooling setups:
