Digital PTZ
Digital PTZ is a function that allows easy panning, tilting, and zooming by transmitting only a part of the camera
effective pixel area without moving the camera lens position that was adjusted during camera installation.
Note
If Digital PTZ is enabled while receiving H.264 video, the received video changes to JPEG format.
