Mitchell Starc dismissed KL Rahul on Day 1 of the Perth Test in the Border Gavaskar Trophy as Alex Carey caught the set batter just before the lunch break.
Despite being given not out by the on-field umpire, the third umpire overturned the decision as Rahul looked in disbelief as he walked off and believed he didn’t edge the ball, sparking a controversy among spectators.

This dismissal again raised the question regarding the unavailability of the hotspot technology. The Sporting News tells you why it is not being used in the Border-Gavaskar Trophy (BGT).
India vs Australia Tests: Why is hotspot technology unavailable in Border Gavaskar Trophy?
Channel 9, the Australian broadcasters were the first ones to introduce this hotspot technology in the 2006/07 Ashes series where they started using infrared cameras to catch the friction between two bodies with a black and white image which is available to the TV umpire.

However, over time it was found that the technology was not 100% accurate and could be manipulated as explained by Warren Brennan—the inventor of the technology. He said that extra coating of silicone on the bat can affect the outcome of the tech.
How does the Hotspot technology work?
In this technology, two thermal imaging (infrared) cameras are placed on opposite ends of the ground and they capture heat signatures that the ball generates through friction when it touches a batter’s bat, pad or any body part.
Why is Hotspot not used extensively when making DRS calls?
To be clear, cricket’s governing body, the International Cricket Council (ICC) have never included the Hotspot as one of the technologies to be used in Decision Review System (DRS) calls for any of their tournaments.
The decision to use it in bilateral series is entirely left to the individual boards and broadcasters.
The usage of Hotspot has decreased in recent years as it is a military technology and is very expensive (which costs around $10,000 per day) for the broadcasters.
Which cricket boards still use Hotspot technology?
Cricket Australia were the only board which extensively used the technology during home matches, although they have decreased its usage as well.
Board of Cricket Control in India (BCCI) have opposed it usage due to the cost and inaccuracy.
England’s Sky Sports and South Africa’s SuperSport had also stopped using the technology many years ago.
