The TJ20 virtual tracking jib is a manual jib system that moves the camera within a certain range by mounting the CD15 or CD20 virtual tracking head. Equipped with high-precision absolute angle sensors on the pan and tilt of the arm. The system’s locator collects data from these sensors, gathers the head’s angle data, combines it with the arm length and other structural data, and calculates the camera’s position and angle in real time.
