1. An occupancy-sensing apparatus, comprising:
- a device control assembly configured to be toollessly inserted into or removed from a cavity of a backplate mounted in an electrical junction box by a user, the backplate including backplate electrical contacts connected to electrical wiring within the electrical junction box, the backplate including a user-translatable cover configured to electrically shield the backplate electrical contacts when in a closed position and expose the backplate electrical contacts when in an open position, wherein the backplate includes a lock to maintain the cover in the closed position unless the device control assembly is inserted into the cavity, the device control assembly comprising;
device control assembly electrical contacts configured to couple to the backplate contacts when the cover is in the open position;
a detector configured to generate an image;
one or more illumination sources, the one or more illumination sources configured to emit illumination including at least one wavelength of radiation measurable by the detector; and
a controller communicatively coupled to the detector, the controller configured to;
receive illuminated images from the detector generated with illumination from at least one of the one or more illumination sources;
generate processed images with filtered ambient light by subtracting an ambient image from the illuminated images, the ambient image generated without illumination from the one or more illumination sources;
classify one or more objects in the processed images as one of human or non-human based on shapes of the one or more objects; and
detect occupants when at least one human object is identified in a processed image.

Abstract
An occupancy-sensing apparatus a device control assembly including a detector configured to generate an image wherein the device control assembly includes one or more illumination sources configured to emit illumination including at least one wavelength of radiation measurable by the detector. The apparatus includes a controller communicatively coupled to the detector configured to detect occupants based on the image generated by the detector, wherein the controller is configured to determine an active state of the detected occupants, the activity state including at least one of a stationary state or moving state.
