Abstract
Devices, methods, and systems for occupancy detection are described herein. One device includes instructions to receive an image of a portion of a facility captured by an imaging device, the image defined by a field of view, and set a first occupancy detection threshold for a first part of the field of view and a second occupancy detection threshold for a second part of the field of view.
Claims20
A non-transitory computer-readable medium having instructions stored thereon executable by a processor to:
- receive an image of a portion of a facility captured by an imaging device, the image defined by a field of view;
- and
- set a first occupancy detection threshold for a first part of the field of view and a second occupancy detection threshold for a second part of the field of view, wherein the first occupancy detection threshold and the second occupancy detection threshold comprise different periods of time between motion detection events required for a determination of occupancy.
A method for occupancy detection, comprising:
- receiving an image of a portion of a facility captured by an imaging device;
- monitoring for motion in the received image, wherein when monitoring for motion in the received image:
- using a first sensitivity for motion detection in a first region of the received image;
- and
- using a second sensitivity for motion detection in a second region of the received image, wherein the first sensitivity for motion detection is different from the second sensitivity for motion detection, and the first sensitivity for motion detection and the second sensitivity for motion detection are both non-zero.

A method for occupancy detection, comprising:
- receiving an image of a portion of a facility captured by an imaging device;
- monitoring for motion in the received image;
- determining occupancy when motion is detected in either a first region or a second region of the received image;
- determine un-occupancy when at least:
- no motion is detected in the first region of the received image for a first period of time;
- and
- no motion is detected in the second region of the received image for a second period of time, wherein the second period of time is longer than the first period of time.
