Abstract
Failover system for video surveillance. A video coverage area for each camera in the system is calculated by combining sensory information and optical specifications of each corresponding camera. The video coverage area information is embedded in a corresponding file of each camera and is used to autonomously re-orient operating cameras to cover a failed coverage area due to a non-operating camera.
Claims20
A method comprising:
- deriving position data from a first camera, including:
- sensory information of the camera in the form of global position coordinates based on a global positioning system;
- and
- orientation of the camera using a magnetometer to find a direction relative to north, and an accelerometer to find a direction relative to tilt;
- deriving optical specifications based on physical limitations of the first camera;
- and
- calculating a first video coverage area of the first camera, including systematically combining the derived sensory information and the derived optical specifications;
- and
- embedding the calculated video coverage area information into a corresponding video file.
6 more elements
A system comprising:
- a processing unit in communication with memory;
- and
- a functional unit in communication with the memory, the functional unit including tools to support orientation of one or more cameras in communication with the processing unit, the tools including:
- an information manager to derive position data for the one or more cameras, including sensory information of the camera in the form of global position coordinates based on a global positioning system, orientation information of the camera using a magnetometer to find a direction relative to north, and an accelerometer to find a direction relative to tilt;
- and
- a video coverage manager in communication with the information manager, the video manager to calculate a video coverage area for the one or more cameras using the information derived by the information manager, and to embed the calculated video coverage area into a corresponding file.
3 more elements
A computer program product for use with a camera, the computer program product comprising:
- a computer readable storage device having computer readable program code embodied therewith, which when executed causes a computer to:
- derive position data from a first camera, including:
- sensory information of the camera in the form of global position coordinates;
- and
- orientation of the camera to find a direction relative to north, and a direction relative to tilt;
- derive optical specifications based on physical limitations of the first camera;
- and
- calculate a first video coverage area of the first camera, including systematically combining the derived sensory information and the derived optical specifications;
- and
- embed the calculated video coverage area information into a corresponding video file.
