What is Pan-Tilt-Zoom (PTZ)?

PTZ is an abbreviation for Pan-Tilt-Zoom. PTZ cameras can pan, tilt and zoom.

To pan means rotating horizontally while maintaining a fixed position. The pan motion is similar to the motion of moving the head left or right.

To tilt means rotating vertically up and down while maintaining a fixed position.

Zooming changes the focal width of the camera and thus the field of view.

Video analytics can be used to pan, tilt and zoom automatically to follow objects.
