[0002] Hemispherical cameras are common surveillance and video recording equipment. They are usually capable of 360-degree surround and 90-degree rotation, and can meet the needs of recording the entire hemisphere. They are usually installed on lamp poles, tops of walls, or bottoms of roofs.

[0003] The location of a hemispherical camera is usually connected to a wall or the corresponding floor, and a special connecting base is required when in use. At the same time, some hemispherical lenses do not need to be rotated frequently when in use. Some hemispherical cameras lack a rotating structure and have a relatively simple usage scenario and do not require a rotating structure. Therefore, the base is required to have a structure that can be easily locked to meet the installation needs of a variety of different equipment. Utility Model Content
