3.3.3 Inserting a Filter

MOBOTIX oers a polarization ﬁlter in its range of accessory products for all sensor mod-

ules (except the L10-L12). The polarization ﬁlter prevents unwanted reﬂections from smooth

surfaces. The ﬁlter can be used to provide better facial recognition of the people behind

the windshield of a car, for example. Only one ﬁlter can be used per sensor module, which

then replaces the standard protective glass lens.

Procedure

1. Position the blue lens wrench on the notches of the

protective glass lens. Rotate the wrench to the left

until you feel a stop (max. 300°) and then a little

bit further until the protective glass lens slides out

of the sensor module.

2. If required, clean the inside of the ﬁlter using a

clean, lint-free cotton cloth.

3. Place the ﬁlter on the notches of the blue lens

wrench.

4. Position the ﬁlter with its clips over the two recep

tacles on the sensor module (red arrow on the

image in the margin) and ﬁrmly press onto the

sensor module. Rotate the glass to the right using

the blue lens wrench until you feel a stop.

5. Adjust the polarization ﬁlter according to the camera’s live image on the computer

monitor. Rotate the ﬁlter to the left using the blue lens wrench until you reach the

desired setting (maximum 180°).

6. To readjust the polarization ﬁlter, rotate it back to the right until you feel a stop and

repeat step 4.

7. If required, clean the outside of the ﬁlter using a clean, lint-free cotton cloth.

Note

Note that using the polarization ﬁlter reduces the amount of light that enters the lens

by approximately 50%.
