"trained on them"
" 'We went to almost comical lengths to keep the story a secret,' Carter said. 'That included allowing only the key crew members to read the script, and they had to read it in a room that had video cameras trained on them. It was a new experience.' "
What does the underlined text mean, please? "Watching them"?
Re: "trained on them"
Yes, to "train something on someone" is to aim it at the person. So, cameras trained on people are cameras which are watching (and following) people.
