Match Playing Conditions
23. Law 23 - Dead Ball
23.1 Law 23.4 - Umpire calling and signalling ‘Dead Ball’
In a match where cameras are being used on or over the field of play (e.g. Spydercam), should a ball that has been hit by the batsman make contact, while still in play, with the camera, its apparatus or its cable, either umpire shall call and signal ‘dead ball’. The ball shall not count as one of the over and no runs shall be scored. If the delivery was called a No ball it shall count and the no ball penalty applied, including if appropriate a free hit from the next delivery. No other runs (including penalty runs) apart from the No ball penalty shall be scored.
Should a ball thrown by a fielder make contact with a camera on or over the field of play, its apparatus or its cable, either umpire shall call and signal dead ball. Unless this was already a No ball or wide, the ball shall count as one of the over. All runs scored to that point shall count, plus the run in progress if the batsmen have already crossed.
