Abstract: A system can use a video analytic algorithm and/or other input parameters to identify an event (e.g., theft). Optionally, the system can take action in response. For example, the security system can use video analytics to determine that a person has reached into a shelf multiple times at a rate above a threshold, which can indicate that a thief is quickly removing items from the shelf. A monitoring system can monitor other areas for breaches, such as an entrance to a store or residence. Monitoring entrances and/or exits can be used to determine occupancy, or to determine rush events to prompt customer service action, such as opening additional point of sale stations.

Abstract: Some embodiments are directed to an image director of a patient monitoring system to obtain calibration images of a calibration sheet or other calibration object at various orientations and locations. The images are then stored and processed to calculate camera parameters defining the location and orientation of the image detector and identifying internal characteristics of the image detector, and the information are stored. The patient monitoring system can be re-calibrated by using the image detector to obtain an additional image of a calibration sheet or calibration object. The additional image and the stored camera parameters are then used to detect any apparent change in the internal characteristics of the image detector (10)(S6-4).
