No the staff refused to turn them off but for much of the time they were off. Plus they got recordings from the cameras in June so the FBI knew any and all blind spots.

The big one was they allowed no one in to watch them.

Some would; some wouldn’t. Trump’s attorney said that they could watch in some areas, but in the residence area there are no cameras, she said “for privacy”. So what ever nasty stuff they did there wasn’t recorded.
