1. A method, comprising:
operating a person detection device (PDD) in a motion sensor mode of operation;

operating the PDD in the occupancy sensor mode of operation;
wherein operating the PDD in the occupancy sensor mode of operation comprises: monitoring, by the PDD, a subset of thermal elements of a thermal detection device of the PDD; determining, by the PDD, a possibility that a person is in an area being monitored by the PDD as a result of monitoring the subset of thermal elements; in response to determining a possibility that a person is in the area, monitoring, by the PDD, all of the thermal elements; and determining, by the PDD, that a person is in the area based on monitoring all of the thermal elements.
6. A person detection device (PDD) for detecting motion and occupancy of a person in an area, comprising:
a memory for storing processor-executable instructions;

cause the PDD to be configured to operate in an occupancy sensor mode of operation in response to receiving the command; and
operate the PDD in the occupancy sensor mode of operation;
wherein the processor-executable instructions that cause the PDD to operate in the motion sensor mode of operation cause the PDD to: detect, via the person detector, that a first person is present in an area being monitored by the PDD; determine that a first dwell time has expired; and transmit, via the transceiver, a person-present signal only when the first dwell time has expired, and the processor-executable instructions that cause the PDD to operate in the occupancy mode of operation cause the PDD to: detect, via the person detector, that a second person is present in an area being monitored by the PDD; determine that a second dwell time has expired, the second dwell time being less than the first dwell time; and transmit, via the transceiver, a person-present signal only when the second dwell time has expired.
7. The PDD of claim 6 , wherein the person detector comprises a single sensor.
8. A person detection device (PDD) for detecting motion and occupancy of a person in an area, comprising:
a memory for storing processor-executable instructions;
