The Portal User can choose between Relative and Continuous PTZ modes. In Relative mode the camera will move by a predefined angle with every click, changing the speed will change how far the camera will move with every click. Zoom has separate speed control but also will zoom in/out by a predefined amount based on the selected speed. In Continuous mode, the camera will keep moving in the direction of the joystick. The closer the joystick to the edge of the control area the faster the camera will move. Zoom still works the same way as in Relative mode.
