Is there a way to turn off NDI on the NDI PTZ1 but leave the HDMI output on? I have a camera with two groups that use the room for meetings. Group #1 uses the NDI through their network out to various monitors. Group #2 is an outside group who uses the room occasionally and use the NDI PTZ1 internally through the HDMI to a monitor in the room. For privacy reasons, we would like to somehow turn off the NDI feed to Group #1's network when Group #2 uses the room so they can't eaves drop on the meeting. Is this possible? Thanks!
