Optical system
By means of lenses, mirrors and
sensors, the area to be monitored is
divided into numerous fields, or so-called
segments. If a person moves from one
segment to the next, this movement is
detected. The greater the number of
segments, the smaller the movement that
can be detected.

Light measurement
To extend the function, presence
detectors can be fitted additional
sensors.
The devices of Busch-Jaeger are fitted
with a light measurement. This extends
the simple On/Off switching process by
one brightness-value threshold.
The brightness threshold determines the
luminosity from which the light switches
on. If the surrounding light is brighter that
the set brightness threshold, the light
does not switch on, or it switches off.
