The abbreviation of Pan/Tilt/Zoom, the concept of security monitoring equipment, represents the omni-directional (left and right/up and down) movement of the pan/tilt and the zoom and zoom control of the lens. This word is usually mentioned, and it can be easily understood as PTZ control.
In the scene range monitored by the camera, when a moving target appears, the user can manually lock it (for example, by clicking the mouse to lock the target) or the preset position automatically triggers and locks a moving target to trigger the PTZ camera to perform autonomous and automatic PTZ tracking. And automatically control the PTZ camera’s pan-tilt to rotate in all directions, and perform visual-oriented automatic tracking of the locked moving target to ensure that the tracking target continues to appear in the center of the lens. The automatic PTZ tracking module makes up for the shortcomings of the narrow view of the fixed camera monitoring, and is a necessary function for a complete security monitoring system.
