High Quality Content by WIKIPEDIA articles! The rail cam made a public debut in the NHL on November 20, 2006 in the Colorado Avalanche/Dallas Stars hockey game. The Versus cable television network used the camera as much as they could during the game to test it out for a live use on a nationally broadcast program. The camera is fastened to a rail system that runs on the top of the glass on one side of the ice rink. As the play shifts from end to end, the motorized mount allows the camera to follow the action, sliding rapidly down the side of the ice. This creates a unique view for the television audience as they get to experience the action much closer than before. Fletcher Chicago is responsible for developing and supplying this new camera system.
