The "blank the camera" button is a feature we added for instructors that do not want their image to be recorded but are scheduled in a classroom with a camera installed. At the start of the lecture, instructors should check the confidence monitor near the touch panel to get a preview of what is being recorded and make adjustments on the touch panel if needed. The confidence monitor shows two streams: The left side shows the projection stream, and the right side shows the camera stream.
By blanking the camera, Course Capture will record a black screen rather than the camera. In some rooms, due to technical limitations, this button will pan toward the ceiling rather than show a black screen.
Here's a screenshot of a typical touch panel. The one for your room might differ slightly.
Always check the confidence monitor to get a preview of what is being recorded.
note: Confidence monitors are only installed in classrooms with cameras.
