The CobraCrane ProLine Pan Tilt Head is a dual-axis motion control system for lightweight cameras up to 6.5 lb. The head provides for real-time joystick controlled motorized pan and tilt. Both axis' can rotate more than 360°, as well as be constrained to any user-definable degree range.
Speeds can be adjusted from as slow as 0.05° per second to as much as one rotation per second. The system also supports stop-motion, repeatable motion, and scheduled movements for both video and user-definable time-lapses. It works in both real-time mode where the system follows a joystick or controller, or schedule mode where you can tell it what to do using keyframes to change items over time.
