Reliable
All BX SHIELD models feature a digitally
enhanced signal recognition logic called
SMDA increasing detection reliability. By
analysing the detection patterns and
environmental information SMDA can
differentiate between genuine intrusions
and a number of noise factors such as
changes in weather conditions and swaying
vegetation.

etc.
AND logic function to reduce false alarms
The BX SHIELD only triggers an alarm signal when both upper and lower areas detect movement.
4 PIR technology
The detection range, sensitivity and
alarm output can be set separately for
the left and right detection areas. The
sensor can differentiate between large
and small objects within the detection
area, reducing false activations and
ensuring genuine intruder detection.
Both left and right detection ranges can be independently adjusted. (2.5 to 12 m in 5 steps)

Sabotaged Trouble out
The BX SHIELD triggers independent alarm
outputs for the left and the right detection areas
which is useful when connected to PTZ cameras.
Individual signal outputs (left and right)
For environments where the temperature difference
between the human body and the background is very
small, the extreme high detection mode increases the PIR
sensitivity to prevent any missed alarms.
