1. A system for remotely monitoring a sleeping subject, the system comprising: (4) (2)

a digital camera configured to capture images of a subject, the digital camera including a digital image sensor, one or more local processors in communication with the digital image sensor, and a memory, wherein the digital image sensor, the one or more local processors, and the memory are enclosed in a same housing, and wherein no part of the system is attached to the subject;

a set of instructions stored in the memory of the digital camera and executable locally by the one or more local processors to: receive a plurality of time-sequenced images of the subject from the digital image sensor;

determine a position of a torso region of the subject, using an artificial intelligence module trained to determine a presence and a position of the subject in a subset of images of the time-sequenced plurality of images;

define a bounding box that identifies where the subject is located in the image;

determine a respiration pattern of the subject by performing a biometric analysis on the time-sequenced plurality of images using the position of the torso region within the bounding box determined by the artificial intelligence module, wherein: determining the respiration pattern includes generating a time-varying number corresponding to respiration of the subject, wherein the time-varying number coincides with a depth and a length of each breath of the subject;

cause an indicator corresponding to the time-varying number on a remote notification device to be presented; and

analyze motion outside of the bounding box defined by the artificial intelligence module; and

flag a video clip for review based on greater than a threshold amount of motion being determined by analyzing the motion outside of the bounding box defined by the artificial intelligence module.

2. The system of claim 1, wherein the indicator comprises one or more light emitting diodes (LEDs). (1) (0)

4. The system of claim 1, wherein the set of instructions is further executable to identify, based on the biometric analysis, an activity state of the subject. (3) (0)

9. The system of claim 1, wherein the biometric analysis includes determining whether the subject is moving by performing an actigraphic analysis of the plurality of time-sequenced images of the subject. (0)

10. The system of claim 1, wherein the subset of images comprises a video. (0)

11. A system for remotely monitoring a sleeping person, the system comprising: (5) (3)

a digital camera configured to capture images of a person, the digital camera including a digital image sensor, one or more local processors in communication with the digital image sensor, and a memory, wherein the digital image sensor, the one or more local processors, and the memory are enclosed in a same housing, and wherein no portion of the system is attached to the person;

a remote notification device in communication with a user located out of sight of the person; and

a set of instructions stored in the memory of the digital camera and executable locally by the one or more local processors to: receive a plurality of time-sequenced images of the person from the digital image sensor;

determine a position of a torso region of the person, using an artificial intelligence module trained to determine a presence and a position of the person, in at least one image of the time-sequenced plurality of images;

define a bounding box that identifies where the subject is located in the image;

determine a respiration pattern of the person by performing a biometric analysis on the plurality of time-sequenced images, wherein determining the respiration pattern includes generating a time-varying number corresponding to respiration of the person, such that the time-varying number coincides with a depth and a length of each breath of the person;

cause an indicator corresponding to the time-varying number on the remote notification device to be displayed;

analyze motion outside of the bounding box defined by the artificial intelligence module; and

flag a video clip for review based on greater than a threshold amount of motion being determined by analyzing the motion outside of the bounding box defined by the artificial intelligence module.

12. The system of claim 11, wherein the set of instructions is further executable to: (3) (2)

identify, using the position of the torso region determined by the artificial intelligence module, an activity state of the person; and

communicate information corresponding to the activity state of the person to the user via the remote notification device.

13. The system of claim 12, wherein the activity state of the person includes a sleep state. (0)

14. The system of claim 12, wherein the set of instructions is further executable to cause a change in an environmental control device local to the person, based on the activity state of the person. (0)

15. The system of claim 12, wherein the remote notification device comprises a dedicated device configured to provide information relating to the activity state of the person. (0)

16. The system of claim 11, wherein the artificial intelligence module comprises a neural network. (0)

17. The system of claim 11, wherein the biometric analysis includes determining a movement state of the person by performing an actigraphic analysis of the plurality of time-sequenced images. (0)

18. The system of claim 11, wherein the respiration pattern comprises a respective duration of each inhalation and each exhalation. (0)

19. The system of claim 11, wherein displaying the indicator comprises displaying a changing light pattern on the remote notification device. (1) (0)
