„ 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.

„ Moving the Preview Frame

You can move the preview frame to the desired position.

Click within the preview frame and drag it over the subject 

that you want to see magnified.

The preview frame turns blue when you drag it. 

Click a position outside of the preview frame and the 

preview frame will move to that position. Click the subject 

that you want to see magnified.

When you have obtained control privileges, you can pan, 

tilt and zoom the displayed video using sliders.

After changing the preview frame, the image display area will 

continue to display the cropped video corresponding to the 

preview frame even after the Viewer PTZ panel is closed. 
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 

closes the PTZ panel, the Viewer PTZ will stay on.

„ 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.

When you have obtained control privileges, click the 

[Control for Admin] button to display the Control for Admin 

Panel and perform camera operation and video settings.
