The parameters of the action modes
Each action mode has several parameters that determine their behaviour.
Once they are changed, they are saved together with the respective action
mode, and will be remembered even if the system is turned off.

The optical sensitivity of each individual light barrier can be set with this pa-
rameter. The value 1 represents the highest sensitivity, 9 the lowest. The
smaller the value, the more sensitive the barrier will be to a small change in
reflectance, allowing smaller objects to be detected. The larger the value, the
less sensitive the barrier, and the larger an object must be.
In the case of working without a reflector, the parameter determines the
minimum amount of light that must be reflected by the subject to set a trig-
ger.
This parameter can be used, for example, to blank out small objects
in favour of large ones. For example, when photographing mammals
larger values should be set so there will be no false triggering due to
small objects such as insects passing by.
Select the sensitivity as low as possible (the number should be as large
as possible). The higher the sensitivity (lower the number), the more
challenging the requirements are for the setup of the light barriers
and reflectors. They must be very stable to minimize the risk of false
triggers. If the sensitivity is at its highest level (i.e., 1), even slight vi-
brations or shocks can change the reflection enough to lead to un-
wanted triggers.
