Hi,

Can anyone point me to some explanation of how that overheard flying camera on wires works? I've only seen it used on NFL games, so I thought I'd ask here.

One question I'd like to know more about: what happens if the football hits one of the camera's guide wires? Tiny chance of that happening, but on punts it might be possible.

Thanks.

i dunno i remember the XFL is what first began using it. And in the first game of the XFL they explained all about it but i dont remember what they had to say. I was more interested in those oh so scantily clad strippers errr...i mean chearleaders they had.

They always keep the camera behind the LOS(i may be wrong), So i dont think a ball will ever hit it.

There are 2 Wires that run diagnal across the field and crisscross at the camera. The camera just runs on these wires. If it wants to go say, towards the East endzone and towards the home sideline, or that corner, than the machine the camera is strapped too runs along the wire that runs to that corner.

Its like a pulley in that it keeps sucking the wire in and releasing it behind it. Meanwhile, the other wire is having a similar thing done so that it can go in that direction too.

I know that sounds like a bunch of BS but its hard to explain without some sort of diagram.

As for what happens if it hits the wire, well, i have no clue. I know the camera is behind the LOS so it wont hit the actual camera, but as for the wires, not sure?

Maybe you can find some sort of explanation if you search on yahoo or google.

Ive heard the officials stop play sometimes to tell them to move the camera back some more because the wires..

The NFL has guidelines on it.

The camera system is called "SkyCam".....

And the way it works it as follows:

There is a gyro stabilized housing that holds a camera. The camera is suspended by four cables that run over the four corners of the field. The cables are kevlar coated fiber optic and copper cables that carry the video signal and power to the camera and stabilization system.

At the end of the four cables, there are moterized reels that spool in and pay out wire as needed to "fly" the camera around the field. There is also another overhead transverse cable that helps regulate the height of the camera, above the field. These reels are computer controlled constantly plotting "X", "Y" and "Z" axis of the camera's position and adjusting the reels as needed.

There are two versions of "SkyCam"... One is a standard definition system and the other is high definition. The main difference is the size of the two cameras involved. The SD camera only weighs 3.5 lbs. The HD camera is 9.8 lbs. so the HD version is a lot larger and required a total redesign of the system.

There are two operators that "fly" SkyCam.... One is responsible for the actual movement or flight of the camera housing, while the other is responsible for the zoom, focus and movement of the camera, inside the housing, to follow the action on the field. "Flying" SkyCam is very similar to flying a helocopter, as there is a joystick and pedals to control direction, elevation and pitch.

I've "flown" SkyCam once for about 20 minutes..... It ain't easy.

The camera is not always behind the punter. Sometimes depending on the shot desired, the camera is either to the sideline or very low (about 20 feet) above the field and behind the defenders. SkyCam moves very quickly. It can move at speeds up to 50 MPH.

BTW ~ How do I know so much about this? They use my cameras in both those systems and I was involved in the HD system's redesign.
