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.
Note
• 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.

After changing the preview frame, the image display area will

However, when you reconnect to Admin Viewer, the initial status
will be restored.
Exiting Viewer PTZ
Click the [Viewer PTZ] button again. The Viewer PTZ
panel closes and Viewer PTZ is exited.
Although clicking the close button of the Viewer PTZ panel
