Below article mainly applies to Bosch cameras with a MBF (Motorized Back Focus) and who have the option to apply different lens variants.
Like for example the Dinion/Flexidome 6000, 7000 and 8000 range
Nowadays the majority of the lenses in the Bosch portfolio are IR-corrected lenses.
But it could be that the Lens that you have selected is not IR-corrected, in that case the Camera-MBF requires a different (focus) position in Night-Mode then it has in Day-Mode.
This article describe how to configure your camera to get optimize focus as-well during the day as night
First consult the (Bosch) datasheet or read on the Lens type-plate to check if your lens is:
The Bosch Box and Flexidome cameras who have a motorized back focus have the possibility to configure 2 different focus positions.
This makes it possible to correct NON-IR lenses in Night-Mode
For NON-IR corrected lenses
Since the camera requires a different focus position during the day than it has in night
the camera requires a 2x focus adjustment, please follow below step 1 and 2
Ones both are configured the camera automatically takes the other focus value when switching the IR-cut filter.
Possible you shortly hear the motorized back focus when taking-in his new position.
When you have an IR-corrected lens only 1x focus adjustment is needed,
since the focus point during day-mode is the same as in night-mode (lens will correct the difference)
Note: if you don't trust your lens or you want to test if your IR-corrected lens correctly compensate and works as intended
you can also do the 2x focus adjustment on a IR-corrected lens, you shall see that the "Day" and "Night" focus value is equal
Note: New Feature with 7.10.0074
An auto back-focus command is introduced to initiate an auto back focus adjustment cycle without the need for entering the Lens Wizard.
