PTZ (Pan-Tilt-Zoom) cameras are typically used for applications such as autotracking, active gatekeeper, and guard tour. Autotracking allows the camera to follow moving objects within its field of view automatically.
Active gatekeeper enables the camera to move to a preset position when motion is detected in a specific area.
Guard tour is a function that allows the camera to patrol between preset positions at scheduled intervals. These features enhance surveillance capabilities and are commonly implemented in PTZ cameras. Axis Communications' documentation on PTZ camera functionalities details these applications.
