In the modern era of cricket, technology has become an essential component of fair play. From live ball tracking to ultra-slow-motion replays, today’s matches rely heavily on advanced systems to support on-field decisions. One of the most intriguing technologies used during matches is the Hotspot system. But while many fans are familiar with what Hotspot does, few understand who actually controls it during a live cricket match.

Let’s explore not only who operates this system, but also how it works, how it fits into the decision-making process, and what its limitations are.

Understanding the Hotspot System
Hotspot is a sophisticated imaging system that uses infrared thermal cameras to detect the heat generated when the ball strikes an object. These cameras are usually placed at strategic angles around the field, primarily covering the batsman’s end.

The idea behind Hotspot is simple: whenever the ball makes contact with the bat, pad, glove, or any part of the batsman’s body, the friction causes a tiny amount of heat to be released. This heat registers as a white spot on the infrared image. These visuals are then used as evidence in close decisions, particularly in scenarios involving: Hot Spot (cricket)

Potential catches behind the wicket

Edges that are difficult to detect with the naked eye

LBW (Leg Before Wicket) appeals where contact with the bat is in question

Hotspot became widely known after being used in international matches, especially during the Ashes series. Its accuracy, however, depends on several factors, including camera placement, environmental conditions, and the quality of the equipment.

Who Is in Charge of the Hotspot System?
Contrary to what some fans may assume, the Hotspot system is not operated by the on-field umpires or match officials. Instead, it is controlled by a specialized third-party technical team hired by the tournament organizers or broadcasting partners.

1. Third-Party Technology Operators
   The Hotspot system is developed and managed by private technology firms. One of the most well-known companies responsible for operating Hotspot is BBG Sports, based in Australia. These firms deploy a team of trained technicians and engineers who are responsible for:

Installing the infrared cameras in the stadium

Calibrating and aligning the thermal sensors before the match

Monitoring and maintaining the equipment during the game

Capturing and transmitting relevant footage upon request

These operators have no influence on the outcome of the decision. Their role is purely technical: to ensure that the system runs smoothly and delivers clear, accurate images to match officials and television broadcasters.

2. The Role of the TV Umpire (Third Umpire)
   While the technical team controls the equipment, the third umpire, also known as the TV umpire, is the one who uses the Hotspot visuals to make decisions.

Whenever a team calls for a DRS (Decision Review System) challenge, the third umpire requests footage from several technologies, including Hotspot. The technicians in the control room then provide the footage as quickly as possible. The third umpire examines the thermal images, looking for signs of contact between the bat and ball or pad and ball.

Importantly, the Hotspot system does not make the decision; it simply provides data. The interpretation of that data, and the final decision, rests entirely with the third umpire.

How the Decision Review Process Works with Hotspot
Here’s a step-by-step overview of how the Hotspot system is used during a match:

On-field Decision: The umpire gives an initial decision—either out or not out.

Player Review: A player from either team requests a review through the DRS system.

Third Umpire Involvement: The TV umpire takes over and begins to analyze the incident using multiple technologies.

Hotspot Footage Requested: The third umpire asks the technical team for Hotspot visuals.

Footage Delivered: The technicians provide the necessary clips showing thermal imaging at the point of contact.

Decision Made: The third umpire uses the Hotspot images, along with ball tracking and UltraEdge (if available), to make a final decision.

This process is often completed within a minute or two, but in high-pressure situations, it can feel much longer as every frame is reviewed carefully.

Can Hotspot Be Wrong?
While the technology behind Hotspot is impressive, it is not flawless. There are instances when Hotspot may not detect a genuine edge. Some of the common limitations include:

Low-friction contacts: If the contact between bat and ball is very light, the resulting heat may be too minimal to register on the system.

External interference: Sweat, moisture, or dirt on the bat or gloves can reduce the accuracy of the readings.

Obstructions: The bat or pad may block the camera’s view of the exact point of contact.

Poor calibration: If the cameras are not aligned properly before the match, the footage can be inconclusive.

Because of these limitations, Hotspot is often used in combination with other technologies like UltraEdge (also known as Snickometer), which uses sound waves to detect faint touches.

Why It Matters Who Controls the System
Transparency and trust are key in sports. Knowing that the Hotspot system is operated by an independent, specialized team rather than the cricket board or match officials helps ensure that decisions are free from bias.

This separation of duties—where the tech experts provide the visuals and the umpires make the call—helps maintain the integrity of the decision-making process. It also ensures that players and fans alike can trust the outcome, even in high-stakes moments.

Conclusion
The Hotspot system is one of the most innovative tools in modern cricket, giving umpires a clearer picture of what happens on the field in real time. However, it is not a stand-alone system. Behind every Hotspot image you see on screen is a team of trained professionals working behind the scenes to ensure the technology performs flawlessly.

So, who controls the Hotspot system during a match? It is the responsibility of dedicated third-party technicians, supported by TV umpires who use the data to make crucial decisions. This collaboration between human expertise and cutting-edge technology ensures that cricket remains fair, accurate, and thrilling for everyone involved.
