Abstract
A lighting system comprised of a central controller, a digital communications path, and a plurality of image projection lighting devices (IPLDs) is provided. The IPLDs contain cameras that can capture both visible light and infrared light. Address signals sent from the central controller first address a particular IPLD and then command signals sent from the central controller control an infrared blocking filter to be positioned in and out of a camera optical path of the particular addressed IPLD.
