According to its rotational characteristics, the pan tilt can be divided into horizontal rotating pan tilt that can only rotate left and right, and omnidirectional pan tilt that can rotate both left and right and up and down. Generally speaking, the horizontal rotation angle is 0 °~350 °, and the vertical rotation angle is+90 °. The horizontal rotation speed of a constant velocity platform is generally between 3 ° to 10 °/s, and the vertical speed is around 4 °/s. The horizontal rotation speed of the variable speed pan tilt is generally between 0 ° to 32 °/s, and the vertical rotation speed is around 0 ° to 16 °/s. In some high-speed camera systems, the horizontal rotation speed of the pan head can reach over 480 °/s, and the vertical rotation speed can reach over 120 °/s
