Focus:
Enable WDR enhanced : This function allows users to identify more image details with an
extreme contrast from an object of interest with one shadowed side against a bright background,
e.g., an entrance. You may select the Enable WDR enhanced checkbox, and then adjust the
strength (low, medium, high) to reach the best image quality.
Enable WDR Pro : This refers to the Wide Dynamic Range function that enables the camera
to capture details in a high contrast environment. Use the checkbox to enable the function,
and use the slide bar to select the strength of the WDR Pro functionality, depending on the
lighting condition at the installation site. You can select a higher effect when the contrast is high
(between the shaded area and the strong light behind the objects).
The methodology of using the Resize Buttons at the upper left corner of the streaming window is
the same as that on the home page.
5. Wait for the scan to complete. After a short while, the clearest image obtained should be
displayed and the optimal focus range achieved. Use the arrow marks on the sides to fine-tune
the focus if you are not satisfied with the results. You may still need to use the arrow marks to
fine-tune the focus depending on the live image on your screen. “>” means moving from wide to
tele end; and “<” tele to wide.
