General gimbals are wired controlled electric gimbals. There are five input terminals for the control line, one of which is the common terminal of the power supply, and the other four are divided into upper, lower, left, and right control terminals. If one end of the power supply is connected to the common terminal and the other end is connected to the "up" position, the gimbal will drive the camera head to rotate upwards, and so on. Some gimbals are equipped with control circuits such as relays, which often have six control input terminals. One is the common terminal of the power supply, the other four are the upper, lower, left, and right terminals, and the third is the automatic rotation terminal. When one end of the power supply is connected to the common terminal and the other end is connected to the "automatic" terminal, the gimbal with the camera head will automatically rotate up, down, left, and right at a certain speed.
In terms of power supply voltage, there are two common types: AC 24V and 220V. The power consumption of gimbals is generally low for those with small weight-bearing capacity, high for those with large weight-bearing capacity, and small indoor gimbals with DC 6V power supply. A battery can be installed inside the gimbals and remote control can be performed using an infrared remote control. Most gimbals still use wired remote control, and the installation location of gimbals is close to the control center and the quantity is not large. Generally, control signals are directly output from the console for control.
When the installation position of the gimbal is far away from the control center and there are many of them, the encoded control signals are often transmitted through the bus and decoded by the terminal decoder to control the rotation of the gimbal. In order to adapt to the installation of different network cameras and protective covers, the load-bearing capacity of the gimbal should be different. The appropriate load-bearing gimbal should be selected based on the total weight of the selected network camera and protective cover. The load-bearing capacity of indoor gimbal is relatively small, and the volume and weight of gimbal are also relatively small. The outdoor gimbal has a relatively large load-bearing capacity because it is necessary to install a network camera with a protective cover (often an all-weather protective cover) on top of it. It also has a large volume and weight. The factory produced indoor gimbal has a load-bearing capacity of approximately 1 About 5kg~7kg, the outdoor gimbal can support a weight of approximately 7kg~50kg. Some gimbals are miniature gimbals, such as those installed together with cameras in hemispherical protective covers or all-weather protective covers.
