The f-stop value of a lens will get higher if you zoom in. This is true because as the focal length increases (when zooming in), the lens aperture typically becomes smaller, resulting in a higher f-stop value. This change affects the amount of light entering the camera, which is an important consideration for PTZ (Pan-Tilt-Zoom) cameras when they are used in varying lighting conditions.
