Triple-Lens Camera with PTZ Movement
One of the important features of this type of camera is the combination of multiple fixed viewing angles with PTZ movement. PTZ means Pan, Tilt, and Zoom. Pan allows the camera to rotate from side to side, tilt allows it to move up and down, and zoom allows it to get a closer view of an object or person. The additional camera lenses provide coverage while the moving camera can concentrate on a particular event. For example, if a person enters a large compound, the camera can maintain general coverage while the PTZ section turns toward the person's location for a more detailed view.
