OBSBOT 4K tiny

We used the OBSBOT Tiny 4k web cam for zoom conference.  There are 20 people who joined the meeting.   Network speed was good (more than 100 Mbps for both upstream and down stream).  However, the quality of the image on the receiving side was bad and sometimes choppy (missing frames) .  The quality of the cloud recording was also bad. The license of Zoom is professional.   Does anyone has possible solution for this symptom?
