Focus
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.
Below is the procedure to perform the automated Focus function:
1. Select from the bottom of the screen whether you want to perform focus adjustment on
the Full view or within a Custom focus window. You can create a custom window and
click and drag the window to a desired position on screen.
2. It is recommended to Reset to the default back focus position of the sensor board.
3. You can use the Fully-opened iris checkbox (default) to increase the iris size for a
better focus adjustment result.
4. Click to select the Fully-opened iris or the Full-range scan buttons. 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. In theory, best results
of the auto scan can be acquired when the camera's iris is fully open.
