Cause and Remedy
Enable the pyroelectric infrared sensor image buffer/transfer
(see page 68 of the Operating Instructions on the Setup CD-
ROM).
Pyroelectric infrared sensor stops during privacy mode.
Disable the privacy mode (see page 81 of the Operating
Instructions on the Setup CD-ROM).
Even if the obstacle is made of glass or acrylic plastic, it
affects the pyroelectric infrared sensor performance.
Remove the obstacle in front of the sensor.
The pyroelectric infrared sensor detects a temperature
difference between an object and its surroundings in about 5
m detection range (about 30 ° horizontally and about 85 °
vertically). Therefore, the smaller the temperature difference
is, the shorter the detection range gets. If there is no
temperature difference, the pyroelectric infrared sensor may
not detect anything. On the other hand, if there is a large
temperature difference, the detection range gets longer.
Clean the pyroelectric infrared sensor with a soft cloth.
