Abstract

An apparatus configured to sense presence and motion in a monitored space includes one or more thermal sensing devices and a lens array. Each thermal sensing device is configured to produce a direct current output that is sustained at a level substantially proportional to an amount of thermal energy being received at the thermal sensing device. The lens array is coupled to the one or more thermal sensing devices and includes multiple lenses, each of which is configured to direct incident thermal energy from at least a respective one of multiple different physical zones located within the monitored space onto the one or more thermal sensing devices.
