Abstract: A graphical work station for use with security devices associated with a location in which the graphic work station provides a graphical image and direction relative to the graphical image enables functions to be performed within the work station, at the security devices and/or with respect to the location.

Abstract: A surveillance device having a camera and lens assembly in which a condition of the assembly is controllable by a movable part and in which a closed loop digital motion control system is used to control the movable part and, therefore, the condition. The closed loop motion control system includes a dedicated digital signal processor which is used exclusively to control the movable part. The digital motion control system also includes a drive motor which is responsive to the digital signal processor and a digital encoder which monitors the position of the movable part and provides encoded position signals to the processor. Movable parts for the pan and tilt assemblies of the surveillance device are controlled by separate closed loop motion control systems each having its own dedicated digital signal processor.

Abstract: A method and system for use in a computer controlled video surveillance system are disclosed for storing and retrieving data relating to information recorded on a video tape, thereby locating visual information recorded on a video tape. The system comprises means for recording visual information on a plurality of segments of a video tape, each of the segments being defined by a time at which its recording begins and a time at which its recording ends. Means are provided for recording a tape identification code on the plurality of segments of the video tape. A tape counter generates a tape count such that for each segment, a corresponding initial tape count is generated at the time when recording of that segment begins. The invention further comprises a database. Stored in the database is a log corresponding to the video tape. The log comprises a record relating to each segment. Each record contains searchable fields.

Abstract: A controller for use in generating signals for enabling control of a plurality of functions of a camera and lens assembly comprising a movable member having a first region adapted to be engaged by a user's first finger for moving the movable member in a plurality of directions to develop first and second signals for controlling first and second functions of the camera and lens assembly, and at least a plurality of further regions with each of the further regions being finger reachable by another finger of the user when the user's first finger is engaging the first region and being adapted to be finger actuatable to develop a signal for enabling control of a further function of the camera and lens assembly.

Abstract: A camera surveillance system in which a master adjustable camera selects a position in a premises and transmits information related to the selected position to a slave adjustable camera. Based on this related information, the slave adjustable camera trains on or views the selected position.

Abstract: A surveillance assembly wherein the assembly utilizes a solid state image pickup which is separately mounted from a camera body of a solid state camera and wherein a shutter is utilized for shielding the viewing region of the assembly.
