Parameter Description Change
Internal
illuminator Select or deselect the option to enable/disable
the illuminator fitted on the sensor. Press the SET button to
enable/disable the option.
External
illuminator Select or deselect the option to enable/disable
the strobe signal that the sensor can use to pilot
the external illuminator. Press the SET button to
enable/disable the option.
Exposure time The exposure time identifies the period that the
lens remains open and allows light to reach the
CMOS mounted on the sensor. Therefore, the
longer the exposure time, the brighter the image
will be. On the other hand, increasing the
exposure times increases the risk of acquiring
blurred images where the detail being monitored
moves at a certain speed. If the images of
objects that move quickly are not very bright, it
is recommended to adjust the gain settings. To adjust the exposure
time, move to the option
and use the RIGHT/LEFT
ARROW
buttons.
Gain The gain setting allows you to adjust the
brightness of the image acquired by the sensor
by amplifying the signal transmitted by the
CMOS to the processing unit. Increasing the
gain setting, however, also increases the
disturbance on the image which decreases its
quality. To adjust the gain setting,
move to the option and use
the RIGHT/LEFT ARROW
buttons.
Negative Select the option to enable the inversion of the
grey tones. This creates a negative image
compared to the one currently acquired by the
sensor (i.e. white turns to black and vice-versa).
Press the SET button to
enable/disable the option.
Once the camera settings have been completed, it is possible to return to the Setup menu by pressing
the TEACH button. This procedure saves all the modifications made to the settings.
