Sports shooting with a battery of remotes?

[Doc Nickel]

Linked from another thread, I started poking around sportsshooter.com, especially getting a kick out of the "Fun Pix" section.

I was looking through and drooling over the equipment and came across this photo (http://www.sportsshooter.com/funpix_view.html?id=4128) of someone setting up a battery of apparently remote-controlled cameras.

Can someone explain to me what's going on? I know of having remotely-fired cameras above volleyball nets or basketball hoops, but why a battery of six at ankle-height, all so closely spaced, and in addition to the handhelds?

What's the theory behind this idea?

Your assuming all of those cameras are one photographer. Probably not one photog, but probably all remoted due to the angle.

I guess I was. That would make sense that it's a collection of photographers' remotes (especially since there's both Nikon and Canon on the lower row...)

So in that case, who provides the mounting rail (or whatever they're attached to- it doesn't look like a series of small tripods.)

I think they're sitting on blocks or bean-bags. As a side note, that Domke F5 looks almost as beat as mine do.
