Description:
Panning refers to the horizontal movement or rotation of a film or video camera, or the scanning of a subject horizontally on video or a display device.
Tilting is a cinematographic technique in which the camera is stationary and rotates in a vertical plane (or tilting plane).Tilting the camera results in a motion similar to someone nodding their head "yes".
A zoom lens is a mechanical assembly of lens elements with the ability to vary its focal length (and thus angle of view), as opposed to a prime lens which has a fixed focal length.

This three options transfers camera to very mobile watching unit. usually Panning suppots rotation up to 360 degree. Tilting - 90 degree. Zoom depends on lenses up to 10x optical zoom.
