• one or more processors and memory storing one or more programs for execution by the one or more processors, the one or more programs including instructions that cause the one or more processors to:
• receive detection inputs from the sensor;
• perform a first presence evaluation based on the detection inputs, wherein the first presence evaluation determines that there is a presence or an absence of persons in the viewing area for an amount of time that satisfies a first threshold;
