A pan-tilt-zoom (PTZ) camera is a controllable device that will provide dynamic coverage by having the ability to pan horizontally, tilt up and down, and zoom in and out. Their typical purpose is to monitor wide, expansive areas that need views in the range of 180° or 360°. They can either be controlled remotely by an operator at a computer, or via remote control; as well as having the ability to automatically monitor a pre-programmed area or field of view.
