1. A video-based monitoring system for monitoring an occupant of a room, the monitoring system comprising:
- a video recording device having a field of view within the room;
a processing unit for receiving and processing video data from the video recording device, wherein the processing unit is configured to define plural zones within the field of view of the video recording device, each zone being associated with at least one algorithm, stored in the processing unit, for detecting and classifying a movement of the occupant in the respective zone; and
the plural zones correspond at least to a bed zone and a zone within the room outside of the bed that is adjacent to the bed zone;
the algorithm associated with the zone adjacent the bed zone being programmed to classify the movement of the occupant in the zone adjacent the bed zone based on the type of movement and movement of the occupant into the zone adjacent the bed zone from the bed zone.

14. A method of monitoring the movement of an occupant of a room, the method comprising the steps of:
-
receiving video data from plural zones within the field of view of a sensor, the field of view being within a room, the plural zones including at least a bed zone and a zone outside the bed zone that is adjacent to the bed zone; monitoring the plural zones to detect a movement of an occupant in each zone according to respective motion detection algorithms corresponding to each zone; and classifying a movement of the occupant in a zone of the plural zones based on the corresponding algorithm, the algorithm associated with the zone adjacent the bed zone being programmed to classify the movement of the occupant in the zone adjacent the bed zone based on the type of movement and movement of the occupant into the zone adjacent the bed zone from the bed zone. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method of monitoring the movement of an occupant of a room, the method comprising the steps of:
-
receiving video data from an activity zone of a plurality of zones defined within a field of view of a sensor, the plurality of zones including a bed zone and a door zone, the activity zone being away from the door zone and the bed zone, monitoring the plurality of zones to detect a movement of an occupant in each zone according to respective motion detection algorithms corresponding to each zone;
classifying a movement of the occupant in a zone of the plurality of zones based on the corresponding algorithm, the algorithm associated with a zone adjacent the bed zone being programmed to classify the movement of the occupant in the zone adjacent the bed zone based on the type of movement and movement of the occupant into the zone adjacent the bed zone from the bed zone;detecting a movement event of an occupant taking place within the activity zone; tracking at least one property of the movement event, the at least one property comprising; a type of movement event, a frequency of movement events, a duration of the movement event, or a time elapsed between movement events; and activating a response based on the at least one property of the movement event.

32. A method of monitoring the movement of an occupant of a room, the method comprising the steps of:
-
receiving video data from a high risk zone of a plurality of zones defined within a field of view of a sensor, the high risk zone containing a danger area, the plurality of zones including a bed zone; monitoring the plurality of zones to detect a movement of an occupant in each zone according to respective motion detection algorithms corresponding to each zone;
classifying a movement of the occupant in a zone of the plurality of zones based on the corresponding algorithm, the algorithm associated with a zone adjacent the bed zone being programmed to classify the movement of the occupant in the zone adjacent the bed zone based on the type of movement and movement of the occupant into the zone adjacent the bed zone from the bed zone;detecting a movement event of an occupant taking place within the high-risk zone; tracking movement of an occupant in the high-risk zone, when the movement is either near the danger area or within the danger area; and activating a response based on the tracking of the movement. - View Dependent Claims (33)
