  • Context aware surveillance system using a hybrid sensor network
    Patent number: 7619647
    Abstract: A surveillance system detects events in an environment. The system includes a camera arranged in the environment, and multiple context sensors arranged in the environment. The sensors are configured to detect events in the environment. A processor is coupled to the camera and the context sensors via a network.
