Yuntai is a part of tripod. A tripod is a multi-part tool that supports cameras or camera-assisted shooting. After the camera or video camera is fixed, the pan/tilt can freely adjust the direction and angle to a suitable degree to shoot. Pan-tilt is a "platform" installed on the top of tripod to fix the camera (or video camera), and its function is to control the camera's all-round angle to facilitate shooting from different angles. The tripod is of course a tripod, and the camera is fixed by the tripod head on it. The two can be disassembled separately, and the same tripod can be installed on different tripods.
