The guards we can bypass easily with a Mind Trick, unless someone wants to talk their way through. It wouldn't be Gallagher. But the camera would need Intrusion and Fix-It to take care of, so someone would need to get to it unseen and either turn it off quietly or loop the footage so we aren't spotted.
the swimteam can perhaps get on the ship, go to the camera and disable it?
Still, a mind trick would mean that the next team has to do this as well (IF they have it!) so perhaps taking them down after looping the camera is better? Like, knocking them down and cuffing them or something?
PS: mid-january I have some exams, so between 11 & 20 january I'll be rather busy
