## Abstract

A system of user detection includes a camera configured to rotate to a plurality of positions, a memory that stores a module, and a processor coupled, locally or remotely, to the camera. The processor is configured to send a command to the camera to cause the camera to (1) rotate to a position from the plurality of positions, and (2) capture a photo or a video clip at the position. The processor is configured to receive the photo or the video clip from the camera; determine whether a user is captured in the photo or the video clip; divide the photo or the video clip into a plurality of zones; determine a zone from the plurality of zones where the user appears in the photo or the video clip; and determine whether the user is associated with a device based on information of the position and the zone.

## Claims

### Claim 1

A system of user detection, comprising:
a camera configured to rotate to a plurality of positions;
a memory that stores a module; and
a processor coupled, locally or remotely, to the camera, configured to run the module stored in the memory that is configured to cause the processor to:
send a command to the camera to cause the camera to (1) rotate to a position from the plurality of positions, and (2) capture a photo or a video clip at the position, receive the photo or the video clip from the camera,
determine whether a user is captured in the photo or the video clip,
divide the photo or the video clip into a plurality of zones,
determine a zone from the plurality of zones where the user appears in the photo or the video clip, and
determine whether the user is associated with a device based on information of the position and the zone.

### Claim 2 (depends on 1)

The system of claim 1, wherein the module is further configured to cause the processor to recognize a face of the user.

### Claim 3 (depends on 1)

The system of claim 1, wherein the module is further configured to cause the processor to recognize a landmark in the photo or the video clip, and wherein determining whether the user is associated with the device is further based on the landmark.

### Claim 4 (depends on 1)

The system of claim 1, wherein the module is further configured to cause the processor to send the command periodically.

### Claim 5 (depends on 1)

The system of claim 1, further comprising a sensor that is attached to the device, wherein the sensor is configured to detect a likelihood of having the user enter or leave a target area, and, in response, send a notification signal to the processor, wherein the module is further configured to cause the processor to send the command signal based on receiving the notification signal.

### Claim 6 (depends on 1)

The system of claim 1, further comprising a sensor that is attached to the device, wherein the sensor is configured to detect a change of motion within a target area, and, in response, send a notification signal to the processor, wherein the module is further configured to cause the processor to send the command signal based on receiving the notification signal.

### Claim 7

A system of user detection, comprising:
a camera configured to rotate to a plurality of positions;
a memory that stores a module; and
a processor coupled, locally or remotely, to the camera, configured to run the module stored in the memory that is configured to cause the processor to:
send a command to the camera to cause the camera to (1) rotate to a position from the plurality of positions, and (2) capture a photo or a video clip at the position,
receive the photo or the video clip from the camera,
divide the photo or the video clip into a plurality of zones,
determine whether a user is captured in a zone from the plurality of zones, and
determine whether the user is associated with a device based on information of the position and the zone.

### Claim 8 (depends on 7)

The system of claim 7, wherein the module is further configured to cause the processor to recognize a face of the user.

### Claim 9 (depends on 7)

The system of claim 7, wherein the module is further configured to cause the processor to recognize a landmark in the photo or the video clip, and wherein determining whether the user is associated with the device is further based on the landmark.

### Claim 10 (depends on 7)

The system of claim 7, wherein the module is further configured to cause the processor to send the command periodically.

### Claim 11 (depends on 7)

The system of claim 7, further comprising a sensor that is attached to the device, wherein the sensor is configured to detect a likelihood of having the user enter or leave a target area, and, in response, send a notification signal to the processor, wherein the module is further configured to cause the processor to send the command signal based on receiving the notification signal.

### Claim 12 (depends on 7)

The system of claim 7, further comprising a sensor that is attached to the device, wherein the sensor is configured to detect a change of motion within a target area, and, in response, send a notification signal to the processor, wherein the module is further configured to cause the processor to send the command signal based on receiving the notification signal.

### Claim 13

A method for user detection, comprising:
sending, at a server to a camera, a command to cause the camera to (1) rotate to a position from the plurality of positions, and (2) capture a photo or a video clip at the position;
receiving, at the server from the camera, the photo or the video clip;
determining, at the server, whether a user is captured in the photo or the video clip;
dividing, at the server, the photo or the video clip into a plurality of zones;
determining, at the server, a zone from the plurality of zones where the user appears in the photo or the video clip; and
determining, at the server, whether the user is associated with a device based on information of the position and the zone.

### Claim 14 (depends on 13)

The method of claim 13, further comprising recognizing a face of the user.

### Claim 15 (depends on 13)

The method of claim 13, further comprising recognizing a landmark in the photo or the video clip, and determining whether the user is associated with the device is further based on the landmark.

### Claim 16 (depends on 13)

The method of claim 13, wherein the command signal is sent periodically.

### Claim 17 (depends on 13)

The method of claim 13, further comprising receiving, from a sensor, a notification signal that indicates a likelihood of having the user enter or leave a target area, and wherein the command signal is sent based on receiving the notification signal.

### Claim 18 (depends on 13)

The method of claim 13, further comprising receiving, from a sensor, a notification signal that indicates a change of motion within a target area, and wherein the command signal is sent based on receiving the notification signal.

### Claim 19

A method for user detection, comprising:
sending, at a server to a camera, a command to cause the camera to (1) rotate to a position from the plurality of positions, and (2) capture a photo or a video clip at the position;
receiving, at the server from the camera, the photo or the video clip;
dividing, at the server, the photo or the video clip into a plurality of zones;
determining, at the server, whether a user is captured in a zone from the plurality of zones; and
determining, at the server, whether the user is associated with a device based on information of the position and the zone.
