1. A system for determining occupancy in an environment, comprising:
a plurality of sensor bundles, each sensor bundle comprising:
a presence sensor configured to generate a presence signal; and
a motion sensor configured to generate a motion signal; and
a controller in communication with each sensor bundle, the controller configured to:
designate one of the sensor bundles as presence triggered if one or more persons are present within a field of view of the presence sensor of the sensor bundle based on the presence signal and a presence detector; wherein the presence detector comprises criteria used by the controller to analyze the presence signal indicative of presence of one or more persons;
designate one of the sensor bundles as motion triggered if one or more persons are moving within a field of view of the motion sensor of the sensor bundle based on the motion signal and a motion detector; wherein the motion detector comprises criteria used by the controller to analyze the motion signal indicative of motion of one or more persons;
determine a triggered bundle count of the sensor bundles which are both presence triggered and motion triggered; and
determine an occupancy count for the environment based upon correlating, via an occupancy count module, one or more triggered bundle count to one or more occupancy counts.
