    摘要: A door control system is provided. Aspects includes a sensor having a field of view in proximity to a door threshold of an entrance to an occupancy area, wherein the sensor is adapted to detect objects in the door threshold and a landing area proximate to the door threshold, wherein the sensor is operated based on a movement of a door in the door threshold. And based at least upon detecting an object within a portion of the door threshold or the landing area, the sensor operable to signal a door operation controller to perform an action.
