Is there a way to remove/mute the capture-sounds of the instant camera while a player is in vanish?

As an admin I enjoy stalking my population and sometimes would love to capture a moment in a fight / raid / just mucking about and share the moments with them to frame - but doing so distracts them as even though I am vanished they can hear the camera snap a picture.

I came here to say the same thing!  I love to put up a hall of memories on the map with captures from shenanigans on the server, but the camera sound gives it away/distracts players.
