AXIS Q1604 Network Camera
Video and Audio
Focus
You can focus the Axis product under
Video & Audio
>
Focus
. For most applications, the adjustments on the
Basic
tab are sufficient.
If required, additional adjustments can be made on the
Advanced
tab. Before focusing, always click
Open iris
to open the iris to its
maximum. This gives the smallest depth of field and thus best conditions for correct focusing. Click
Enable iris
when finished focusing.
Basic
Follow the on-screen instructions on the
Basic
tab to adjust zoom and focus. 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.
Note
• The back focus (step 2) should only be reset if the camera has been focused previously.
• Set focus as precisely as possible using the focus puller on the lens (step 3) before starting the automatic fine-tuning (step 4).
• If the camera is placed so that it is difficult to look at the image and move the pullers at the same time, you can use the
Focus Assistant to focus the camera; for instructions, see the Installation Guide supplied with the product.
Advanced
The tools on this page can be used to find the optimal focus position. Always open the iris before focusing and enable it when finished
focusing. Focus is measured in the part of the image covered by the
Focus window
. Use the mouse to move and resize the window
and then click
Fine-tune focus automatically
. If needed, click in the
Focus position
bar or on the arrows at the ends of the bar, to
further adjust the focus. The buttons < and > move the focus position one step in either direction. The buttons << and >> move the
focus position multiple steps in either direction. Clicking on the bar sets focus to that position.
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.
