QuickTime player screen-recording detectable by zoom? Dear Zoom Expert or frequent user I want to ask a technical question. During a zoom meeting (educational classroom), Can zoom detect any participant is screen-recording with QuickTime player or other screen-recording app ( not the built-in record function in zoom)? As a student myself, I asked, because during a meeting last week, the instructor speaker mentioned someone was privately screen-recording. below only my photo instead of other student photo, a red REC was actively being displayed. However, I did not press any record button on zoom app. Is there any probability that REC function can be turned on by speaker carelessly? I did not share my screen too.Is the paid version zoom used by my instructor able to detect 3rd party screen-recording? In the class, the instructor is delivering a boring 4-hr long presentatio
