„ Adjusting the Preview Frame Size
Drag the preview frame line to make the frame smaller, 
and a magnified view of the image in the frame will be 
shown in the image display area.
The preview frame turns blue when you drag it. 
• The aspect ratio of the preview frame is always 16:9.
• The Viewer PTZ uses digital zoom, so the higher the digital 
zoom ratio, the lower the quality of the image becomes.

continue to display the cropped video corresponding to the

„ Differences Between Viewer PTZ and Digital 
Viewer PTZ and Digital PTZ are both simple pan, tilt, and 
zoom functions that use the digital zoom function, but they 
have the following differences because they employ 
different operating principles.
