Cropping and Displaying Part of Video
(Digital PTZ)
You can use the Digital PTZ panel to crop and display
part of a camera video in the video display area. It is also
possible to use a preset or home position registered to the
camera.
Digital PTZ
Digital PTZ is a function that facilitates simple panning,
tilting, and zooming without changing the camera lens
position that was adjusted at the time of installation by
transmitting just part of the camera effective pixel area
from the camera to the viewer.
Note
If digital PTZ is enabled while receiving H.264 video, the received
video changes to JPEG format.
