11. Troubleshooting
Problem
The sensors do not work
correctly.
R Sensors are triggered
each time a car
passes by (separated
by more than 5 m)
R Sensors are triggered
when there are no
people near the
camera.
The heat sensor has
trouble making
detections.
People moving towards
the front of the camera
cannot be detected.

Motion detection/heat sensor
R In the following situations, the sensors are triggered by detecting
changes to the temperature and movement of objects.
– When a car enters the detection range. (When a car or light from
a car's headlights enters the detection range, movement is
detected. The high temperature of a car's muffler or bonnet may
cause sensors to be triggered even from 5 m away, or more.)
– When objects that are in the detection range are moved by wind,
such as tree branches or clothes hung out to dry.
– When small animals such as dogs or cats enter the detection
range.
– When rain or snow falls.
→ Adjust the angle of the camera so that it does not face roads.
→ When using motion detection, adjust the detection range with the
[Motion detection range] setting. To avoid mistakenly detecting light
from car headlights at night, set [Motion detection] to [Day only].
→ When using the heat sensor, you can use the heat sensor's lever to
adjust the sensor's angle and the sensor range cap to adjust the
detection range. (See the camera's manuals for more information.)
Heat sensor only
R The heat sensor may make incorrect detections in the follow locations.
– where the camera can be exposed to direct sunlight
– near heating and cooling devices that cause rapid temperature
change
– in a greasy or moist place
– underneath outdoor lights or other areas that can become hot
– near fire or heating devices
– where the camera can be exposed to interference from magnetic
devices
– where reflective objects are in front of the camera and can interfere
with the heat detection, such as glass
– where there are strong light emitting devices such as fluorescent
lights that can affect the temperature
– near devices that emit radio waves, such as mobile phones
R When the outside air temperature is cold, the detection range (approx.
5 m) becomes longer and too many detections may be made.
→ Change the [Heat sensor sensitivity] setting to a lower sensitivity.
R The surface of the heat sensor is dirty.
→ Wipe the surface of the heat sensor with a soft, dry cloth.
R Because of the characteristics of the sensors, the camera may not be
able to detect people moving towards the front of the camera.
→ Perform the following operations.
– Change the camera location so that objects pass the camera
from the sides. (It is easier to detect objects moving sideways
in front of the camera.)
– If you want to detect objects moving towards the front of the
camera, use a commercially available external sensor. (See
the camera's manuals for more information.)
