Where have all of the wires gone?

[Holland Hacker]

I was at Monmouth Park over the weekend and noticed that the wire that used to hang above the finish line was no longer there. I had noticed the same thing a few weeks back at Belmont but didn't really think about it.

I got me to thinking how the "photo-finishes" are judged if there isn't a wire above the track. I always thought the camera was above the wire and track and not at track level.

Does anybody know how photo finishes are caputured?
