Can you give me as much information as possible about how stump cam works?

Question

I'm talking about the camera located inside the stumps, not Pan-Eye, which is the camera used to determine run outs from side on

Answer 1

The stump cam is very helpful to detect the Run outs for thew 3rd umpire and at the same time it has a laser which detects the speed of a bat and ball

Answer 2

The stump cam if i am not mistaken is on the stumps and is a camera that rotates around to see the action that is going on, it is often the problem that they are broken when players are bowled due to the fact of a ball of leather traveelling 90 mph hitting it.The other one i can think of is the side camera that zooms in on the stumps to see if the player is stumped (USing hthe fourth umpire)
