Description

PTZ

technical field

The utility model relates to the field of photographing equipment, in particular to a cloud platform.

Background technique

The pan-tilt is a supporting workbench for installing the camera, and the camera is set on the pan-tilt. Through the adjustment of the PTZ, the lens of the camera can be adjusted to achieve correct shooting of the target.
