Focus
Focus here refers to the Remote Focus, is applicable to cameras that are equipped with 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, for example, shrink and expand due to a wide range of operating
temperatures and the vibration caused by wind.
To perform the automated Focus function, follow these steps:
Select from the bottom of the screen whether you want to perform focus adjustment on the Full view or
Step 1
within a Custom focus window.
You can create a custom window and click and drag the window to a desired position on screen.
It is recommended to Reset to the default back focus position of the sensor board.
Step 2
You can use the Open iris check box (default) to increase the iris size for a better focus adjustment result.
Step 3
Click to select the Fully-opened iris or the Full-range scan buttons.
Step 4
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.
Wait for the scan to complete.
