The visual joystick is a tool that simulates the operation of a desktop joystick.
When activating the visual joystick on a camera, it will look like the figure below:
To use the visual joystick, keep the mouse left-clicked and move it to any position in the image. The further away from the center of the image the mouse is, the faster the camera will move, and vice versa.
To perform zoom operations, click the + and - buttons located in the center of the image. You can also use the mouse wheel, turning it forward will bring the image closer and backward the image will move away. Using the mouse wheel you can also set the zoom speed (Viewed by the control on the left side of the image). The closer the red marking is to the center, the faster the zoom will be, and vice versa.
The movement and zoom sensitivity can be adjusted in the operating scale settings on the page How to configure the Joystick
