Hotspot
One of the most useful technology introduced during the 2006-2007 Ashes Test series,and proves handy for players and umpires alike. Unlike Snickometer that depends on sound waves, Hot Spot depends on heat signatures. Umpires these days use both the technologies in conjunction to come to a decision.
Hotspots are installed in every corner of the stadium to detect the slightest of changes in the ball’s heat signatures.
The software then generates a negative image on which the point of contact is highlighted as a hot spot for a second or two.
