This isn't that big of a deal. The video camera just catches the stage light as it's going out and the red light as it's coming on. Here are just a few examples I found. There are plenty more.

I have a question for you, Michael, since you seem pretty well versed in the stage-lock system. In Mr. Cotten's meeting with Jeff Foster and Mike Rice they told him: "It is not impossible to have a roll back red light with the stage lock on. But, it requires a motion of at least of a half inch to the rear."

My question to you is: How does the system know if you are a half inch behind the beam? I don't think the computer can tell how far you are behind the beam unless the infrared sensor can tell from how much infrared light it's receiving from the reflector. If not, I would think you could roll back until you turned the pre-stage light off.

And this begs the question, if the infrared sensor can tell how much infrared light it receives, why can't it differentiate between infrared light and a flash from a photographers camera?
