I’m not entirely sure how to answer your question. There are any number of types of IR receivers and sensors, and many of them do produce an appropriate signal that can trigger the Art Controller.
It is certainly possible to modify the Art Controller to stay on for a certain number of shots (if you can somehow detect that those shots have been fired), rather than time, but it would require reprogramming to do so. We might be able to assist with some programming examples for similar situations.
