2.6  Adjusting The Lens
Make sure that you see the live image of the camera on the monitor of your computer or 
laptop. Now adjust the lenses one by one until you see the desired image area on your 
monitor:
•  Remove the camera dome using a lint-free cotton cloth.
•  Release the lock ring of the lens, adjust the image sharpness and 
tighten the lock ring again. To avoid damaging the lens mount, 
never turn the lens too far or with force.
•  Mount the dome again using a soft cotton cloth.
Notes
The focusing aid provides a visual aid when setting the image sharpness of 
a MOBOTIX camera lens (see Section 4.3.3 
Image and Audio Settings, Quick 
Controls 
in the 
Software Manual
).
Image focus: Due to the lens  eect  of  the  dome, the focus of the 135 mm 
telephoto lens  shifts slightly  once the  dome has been  mounted. Before   
mounting the dome, the telephoto lens should be rotated by about 90° in a 
counterclockwise direction (against the direction in which the lens is screwed). 
Make sure that you check the focus of the live image with the dome installed 
and readjust the lens, if required.
We  do  not  recommend  (even)  aligning  the  telephoto  lens  horizontally  due 
to the image distortions that occur in the top part of the dome for technical 
reasons.
