What does ", the cameras outside took over" mean? Could you explain to me in a hurry?
When the vote was announced, my brain just would not work out the right percentages to discover whether we had the necessary twothirds majority. Then one of the technicians turned to me with a big smile on his face and said, “You’ve got it!” At that moment, the cameras outside took over and out there in the yard there was a scene of joy almost beyond belief. Then the cameras came back to those of us who were in the studio. I managed to overcome my urge to burst into tears, and expressed my joy and delight that after all these years this had happened and my thanks to my daughters and my family who had shared in the struggle so long.

Answer

My guess is either that 'the cameras' means 'the people with cameras' - and that the camera people had also heard the news, and started trying to take lots of photos.
It could also mean that the television coverage switched from something else, to being from cameras in the yard, which were capturing video of the response of the crowd.
It's not particularly clear. As it appears to be report of someone's experience, they might not have realised that what they said was ambiguous at the time.
