The gimbal is a supporting device for installing and fixing cameras, which is divided into two types: fixed gimbal and electric gimbal. Indoor PTZ has a small load-bearing capacity and no rainproof device. The outdoor gimbal has a large load-bearing capacity and is equipped with rainproof devices. Some high-end outdoor gimbals not only have rainproof devices, but also anti freezing and heating devices. According to its rotation characteristics, gimbals can be divided into horizontal rotating gimbals that can only rotate left and right, and omnidirectional gimbals that can rotate both left and right as well as up and down. Generally speaking, the horizontal rotation angle is 0 ° to 350 °, and the vertical rotation angle is+90 °. The horizontal rotation speed of the constant speed gimbal is generally between 3 ° and 10 °/s, and the vertical speed is around 4 °/s. The horizontal rotation speed of the variable speed gimbal is generally between 0 ° and 32 °/s, and the vertical rotation speed is around 0 ° and 16 °/s. In some high-speed camera systems, the horizontal rotation speed of the gimbal is over 480 °/s, and the vertical rotation speed is over 120 °/s.
Fixed gimbal is suitable for situations where the monitoring range is not large. After installing the camera on the fixed gimbal, the horizontal and vertical angles of the camera can be adjusted. Once the best working posture is achieved, simply lock the adjustment mechanism.
Electric pan tilt zoom is suitable for scanning and monitoring a large area, and it can expand the monitoring range of the camera. The high-speed attitude of the electric gimbal is achieved by two executive motors, which receive signals from the controller to accurately operate and position. Under the action of control signals, the camera on the pan tilt zoom can automatically scan the monitoring area or monitor objects under the control of the monitoring center duty personnel.

Under the action of control signals, the camera on the pan tilt zoom can automatically scan the monitoring area or monitor objects under the control of the monitoring center duty personnel. The gimbal is equipped with two electric motors. These two motors are responsible for horizontal rotation and vertical rotation. The angle of horizontal rotation is generally 350 degrees. Vertical rotation includes 45 degrees, 35 degrees, 75 degrees, and so on. The angle of horizontal and vertical rotation can be adjusted through limit switches.
