What is an Intelligent Accessory?
Accessories are items that attach to a light to change how it behaves.
A normal accessory could be something like a drop in iris kit, a top hat, etc.
An intelligent accessory then is an item that connects to a light and has computer circuitry inside. These will then connect to your light board with a cable.
Examples could be a rotating gobo. Perhaps a DMX Iris. Or maybe a moving mirror. The light board would control how fast the gobo spins, how wide the iris is, or the pan and tilt of the mirror.
At the end of the day, if it’s an accessory with circuits inside, it’s intelligent.
