Ken,
As Ben mentioned should have had a heat set on Ben. Our initial tests went well but that pretty much would have helped him hear you. A direct microphone and headset would have quieted the 15 trains running at one time. Unfortunately he got drowned out a bit.
Second, like Ben indicated we are going to upgrade all the cameras and Wi-Fi to a better leash network to greatly improve / solve that issue.
We are already planning/ preparing improvements based on yesterday.
