6.2 Channel setup
6.2.5 Area parameters:
Up to 3 different operation modes can be defined for each area. The displays of pa-
rameters switch in according to the desired function. The meaning of each mode and
the corresponding functions are described on the following pages:
Areamode
Note: The sensor area is deactivated at the "Max" setting (=0).
Tip: You can change the slider-value in single steps by using the arrow keys of your
keyboard.
If more than the set cells detect a movement, the timer "Max break" (see page 26) is
activated. This function prevents triggering for brief changes of the light conditions etc.
Min.: The alarm is only triggered if at least the number of set cells detects a change in
the sensor area. Thus, too small and therefore irrelevant objects do not cause an
alarm.
Note: Min=0 is the same as Min=1, which means that at least in one cell a movement
has to be detected before the area is triggered.
Sensitivity: Sets the sensitivity for all marked cells of the sensor area. The higher the
value set (1-10), the higher is the sensitivity of the cells.
"Sensitivity" defines the trigger‟s sensitivity of the time interval.
Reset time: Is started when the sensor area initiates an alarm.
After expiration the alarm of the sensor area is reset. This includes: The display of the
area, the internal linking (see "Logic" on page 30) and the transmission of the serial
alarm strings („Alarm OFF strings‟, see page 28) .
NOTE: The alarm relay – if activated – is only reset after expiration of the relay ener-
gizing time set under "Camera options" .

Every sensor area has parameters that can be edited inde-
pendently from the other areas in this dialog box. A selection of
fundamental parameters is shown on the right hand of the edit
field:
Number of cells: The display of activated cells (here 1325) is
only an information and will not be stored in the sensor.
Max.: A change of the picture is only evaluated as an alarm, if
not more than the set cells detect a movement (here: 552).
The desired number of cells is set by means of the slide control
(the value appears absolute and as percentage).
