Hawkeye uses six high-speed cameras to track the ball's trajectory with 3mm precision, helping determine if a ball would hit the wicket. Hot Spot uses infrared cameras to detect heat from friction when the ball contacts the bat, pad, or wicket. A speed gun measures the ball's speed by timing the round trip of an infrared laser burst reflecting off the ball. An inbuilt speed sensor ball measures its speed from the bowler's hand to impact. Snickometer analyzes sound waves to determine if the ball hit the bat or pads when caught behind the wicket.

2. HawkeyeHawkeye consists of six high-speed video cameras placed high above the court to track the trajectory (path followed) of the ball.

3. It can point out the bounce of the ball upto the precision of 3mm.

4. It was invented by Dr. Paul Hawkins a PhD in Artificial Intelligence.

5. The cameras record the movement of ball at the rate of 60 frames per second. Hot Spot (Red Zone)Hot spot uses two infra-red cameras positioned at the either ends of the ground.

6. These cameras sense and measure heat from friction generated by collision such as ball on bat , pad, wickets etc.
