The gimbal is a supporting device for installing and fixing cameras, which is divided into two types: fixed 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. 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.
The maximum load capacity of the gimbal refers to the maximum load capacity it can bear in the vertical direction. The distance between the center of gravity of the camera (including the protective cover) and the working surface of the gimbal is 50mm. This center of gravity must pass through the gimbal rotation center and be perpendicular to the working surface of the gimbal. This center is the maximum load point of the gimbal, and the bearing capacity of the gimbal is calculated based on this point. If the load position is installed improperly and the center of gravity deviates from the center of rotation, increasing the load torque, the actual load capacity will be less than the design value of the maximum load capacity. Therefore, the larger the vertical rotation angle of the gimbal, the greater the deviation of the center of gravity, and the corresponding load-bearing capacity is smaller.
The load capacity of the gimbal is the key to selecting the gimbal. If the load capacity of the gimbal is less than the actual load, it will not only reduce the operating function, but also damage the motor and gears of the gimbal due to long-term overload. The actual load capacity of the gimbal can range from 3kg to 50kg. For the same series of gimbal products, the load capacity when installed on the side is greater than that when installed on the top, and the load capacity of the high-speed type is smaller than that of the ordinary type.
When selecting a gimbal, it is recommended to use a gimbal with control input and network video input/output interfaces installed in a fixed position of the gimbal, and to connect the control input and video output lines of the camera and lens formed by a soft spiral between the fixed and rotating parts (i.e., between the camera and the camera). After installation and use, this gimbal will not cause damage to the connecting wires of the rotating parts due to long-term use. Especially for outdoor gimbals, this should be the case.
