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.
