[VORTEX Camera] Remote Focus settings

Focus here refers to the Remote Focus, applicable to Network Cameras that are equipped with a stepping motor lens. The automated focus adjustment function eliminates the needs to physically adjust camera focus. In an outdoor deployment consisting of a large number of cameras, the auto focus function can be very helpful when these cameras become out of focus after days or weeks of operation. And that can easily result from the effects of natural forces, e.g., shrink and expand due to a wide range of operating temperatures and the vibration caused by wind. 

It is recommended to adjust the focus during daytime or under sufficient lighting conditions. Nighttime focusing may be more susceptible to the influence of lights (such as headlights or signage), resulting in less than optimal focusing.

When a full-range scan is selected, a full-range scan through the camera's entire focal length can take
about 30 to 80 seconds. If not, the auto focus scan will only go through the length where
optimal focus may occur, and that takes about 15 to 20 seconds

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.

IMPORTANT NOTE: Remote focus settings are only available for VORTEX cameras.
