Auto Focus
There are two options for you to ne-tune the camera focus.
Press the button, and the camera rmware will automatically perform an auto-sensing process on its
vari-focal lens to look for the best focus. The process takes about a minute to complete. This function
applies when you see the image is out of focus when the surrounding lighting condition is changed
drastically for some reasons. You can press the button for longer than 1 second to perform a full-range
scan. Forcing a re-focusing may improve the image quality.
Global View: Click on this item to display the Global View window. The Global View window contains a
full view image (the largest frame size of the captured video) and a oating frame (the viewing region of
the current video stream). The oating frame allows users to control the e-PTZ function (Electronic Pan/
Tilt/Zoom). For more information about e-PTZ operation, please refer to E-PTZ Operation on page 92.
For more information about how to set up the viewing region of the current video stream, please refer to
