IPL 2014 has kicked off tonight with Mumbai Indians taking on the Kolkata Knight Riders at Abu Dhabi. Everybody watching the match must have noticed that the on-field umpires have a strap across their shoulders as well as a small camera on top of their caps. These are essentially umpire cams, which add a new dimension to the way we watch the action on the pitch.

The small camera clipped to the tip of the cap, seems to be connected to a battery pack on the umpire’s back. There is a strap running across his shoulders which must conceal the wires connecting the camera to the battery pack as well as a radio relay to transmit the videos back to the production control room.

The umpire cam adds to the long list of cameras used in a stadium that includes the usual TV cameras around the stadium, a stump cam, the super slo-mo cameras as well as the Spidercam, which is basically a camera suspended over Kevlar cables and controlled by motorized winches.
