AXIS Q1635 Network Camera
Note
• Set focus as precisely as possible with the focus ring or Focus Assistant before starting
automatic fine tuning. Using the focus ring normally gives the best result.
• The iris should always be opened to its maximum while focusing. This gives the smallest
depth of field and thus the best conditions for correct focusing.
1. Open the product's home page and go to Setup > Basic Setup > Focus.
2. Under the Basic tab, click Open iris. If the button is inactive the iris is already open.
3. If focus has been set before, click Reset to reset the back focus.
4. Loosen the zoom puller and the lock screw for the focus ring (see Hardware Overview
on page 10) on the lens by turning them counter-clockwise. Move the zoom puller and
the focus ring to set zoom and focus and check the quality of the image in the image
window. If the camera is mounted so that you cannot look at the image and move
the zoom puller and the focus ring at the same time, use the Focus Assistant instead.
See Focus Assistant on page 20.
5. Re-tighten the zoom puller and the lock screw for the focus ring.
6. On the Focus page, click Fine-tune focus automatically and wait until automatic fine
tuning is completed.
7. Click Enable iris. If the button is inactive the iris is already enabled.
8. If needed, make further adjustments under the Advanced tab. See the online help for
more information.
Focus Assistant
Note
• The view in front of the camera should not be changed during focus adjustment (steps
5 and 6). If the camera is moved, or if a finger or other object is placed in front of the
lens, steps 3 - 7 will have to be repeated.
• If movements in front of the camera cannot be avoided, the Focus Assistant should not
be used.
• If the camera is mounted so that the Function button cannot be accessed, you can still
use the Focus Assistant. Follow the instructions below but mount the camera after step
4, pressing the Function button instead and skip step 7.
To focus your network camera using the Focus Assistant, follow steps 1 - 3 under Adjust Focus on
page 19 before you start with the steps below. See Hardware Overview on page 10.
1. Mount or place the camera so that it cannot be moved.
2. Loosen the zoom puller by turning it counter-clockwise. Move the puller to set the
zoom level. Re-tighten the zoom puller.
