FanSee can only have one mainboard output open at a time. If you accidentally have the mainboard link open on multiple devices (like a laptop in the control room and another computer elsewhere), the system gets confused about where to send the camera feeds and won't function properly. You'll need to close all outputs, stop the instance and restart. The control panel will notify you if someone else is already controlling the session, but the mainboard output doesn't have this same protection, so it's important to ensure only one mainboard link is active at any time.
