This makes no sense whatsoever. Amy knew that the livestream was running 24/7 with a permanent ineffaceable record of her record, so why would she care if an irrelevant janitor made up some story about what he claimed to have seen?
That assumed a belief that someone would watch the video, it wasn't exactly made widely available. Another factor is that even when people know they are being filmed, over time they pay less attention to a camera when there is no person associated with it.
