restored.

„ Exiting Viewer PTZ

Click the [Viewer PTZ] button again. The Viewer PTZ

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.

If digital PTZ is enabled while receiving H.264 video, the received 
video changes to JPEG format.
