[0002] With the continuous development of network communication technology, Internet and Internet of Things technology in recent years, smart camera terminal products have been widely used. Spherical camera is a common smart camera in the industry. It is popular because of its ability to rotate greatly and achieve a basically blind spot-free field of view. The camera's rotation methods are mainly divided into horizontal rotation and pitch rotation. The pitch rotation is mostly driven by a motor directly. There are two main types of horizontal rotation: direct motor drive and gear transmission.

[0003] In the prior art, there are rotating camera devices, most of which use motors to drive belts to rotate to adjust the camera angle. However, in colder areas, the belts are easily worn out and broken due to the weather, which makes it impossible to adjust the field of view. Snow accumulates on the exposed rotating joints, and the motor is easily overloaded when the motor drives the camera to rotate, causing the motor to overheat. In addition, it is inconvenient to replace parts of existing spherical cameras, resulting in a cumbersome maintenance process. To this end, we propose a camera rotating structure.
