  • Patent number: 10931920
    Abstract: Traditional approaches to automated monitoring using a pan-tilt-zoom (PTZ) video security system involve the use of programmed patterns/preset tours. In contrast, a camera tour is configured based on operation of a surveillance system during a period of active operation by a user. The configuration accounts for frequency of given views and other measures to provide an automated tour. The automated tour is displayed when the system is not under active control, and can be updated during further periods of active control.

  • Patent number: 9195116
    Abstract: Systems and methods for focus control in a pan-tilt-zoom (PTZ) camera system are described herein. An example of a method described herein includes identifying a set of trace curves associated with the camera system, each of the trace curves specifying relationships between focus lens positions and zoom lens positions for a corresponding camera position, selecting a trace curve using the set of trace curves and one or more of pan angle, tilt angle or installation height of the camera system, and identifying a focus lens position for a current zooming factor of the camera system based on the selected trace curve.
