About focus
You can focus the Axis product under Video & Audio > Focus . The same settings can be found under Basic Setup > Focus .
For most applications, the adjustments on the Basic tab are sufficient. If required, additional adjustments can be made on the
Advanced tab.
Basic
Always open the iris before focusing and enable it when finished focusing. Opening the iris gives the smallest depth of field and
thus best conditions for correct focusing. The pixel counter is used to determine the number of pixels in an area of the image, for
example to ensure that the image size fulfills specific requirements. To position the pixel counter, click on the text and drag
the window to the desired position.
Advanced
Use the tools on this page to find the optimal focus position. Focus is measured in the part of the image covered by the Focus window .
If the camera is not focused after completing the above instructions, try the Full range focus scan . The scan, which can take
several minutes, transforms the focus position bar to a graph where peaks indicate the best focus positions. Click in the graph
to set focus to the desired position.
How to adjust focus and zoom
If the camera is mounted so that you cannot look at the image and access the lens at the same time, use the Focus Assistant,
