The tripod we usually talk about should be understood as a tripod head set. The tripod set is composed of two parts: tripod and head.
Definition of PTZ
Tripod is a mechanical combination of three retractable legs assembled by three cutting bases, which plays the role of height lifting and supporting. The PTZ is a device that connects the tripod with the camera main equipment and can adjust the direction of the main equipment.
Here we mainly talk about Yuntai, which literally means cloud platform and towering platform. In the industrial era, it refers to the fixed device that controls and carries equipment. Now the camera head and the electric stabilizer will be collectively referred to as the head.
Connection port of PTZ
Tripod PTZ generally has two interfaces (excluding expansion ports). One is the interface connecting the tripod at the bottom of the PTZ, and the other is the interface connecting the quick mounting board of the PTZ to the main equipment, such as cameras, video cameras, monitoring video heads, temperature and speed measuring devices, telescope connecting frames, etc. Only the general interface is mentioned here, and the private mode interface of some manufacturers is not in the scope of discussion.
Speaking of the tripod interface, we have to say that there are two international standard screw ports, one is a British standard 1 / 4 'nut and the other is a 3 / 8' nut. The screw hole at the bottom of the camera is an international standard 1 / 4 'British nut, so no matter how the shape of the PTZ quick mounting plate changes, the interface screw is unchanged. The screw on the top of the professional tripod tripod header and the screw hole at the bottom of the head are universal 3 / 8 'standard screw holes, which are much thicker than the 1 / 4' screw holes. This is also to meet the load-bearing capacity and stability requirements of the tripod.
There are also a small number of small PTZ, and 1 / 4 'nuts are also developed at the bottom. This is mainly designed for mobile phones and mobile devices, and it is used when the load-bearing capacity is not high.
