The abbreviation of the concept of Pan/Tilt/Zoom for security monitoring equipment, which represents the full-scale (left/right/up/down) movement of the pan/tilt and the zoom and zoom control of the lens. Usually, this term is commonly understood as pan/tilt control.
In the scene monitored by the camera, when a moving target appears, the user can manually lock (for example, by clicking the mouse to lock the target) or automatically trigger the preset position to lock a moving target, triggering the PTZ camera to perform autonomous and automatic PTZ tracking, and automatically control the pan/tilt of the PTZ camera to rotate in all directions, and perform visually guided automatic tracking of the locked moving target to ensure that the tracked target continues to appear in the center of the lens. The automatic PTZ tracking module makes up for the shortcoming of the narrow field of view of fixed camera monitoring, and is a necessary function for a complete security monitoring system.
