Problem
The sub monitor, the AC
adaptor, or the charger is
warm.
Camera (sensor operations)
Problem
Monitoring can be
performed with the
camera but sensor
notifications are not
received.
Sensors do not make
detections.
R The motion detection
and heat sensor do
not work
R This is normal. (It may feel a little warmer in summer than in winter.)
→ If it feels very hot, disconnect the AC adaptor from the power outlet
and contact an authorised service centre.
R The camera (sensor detection) is turned off.
→ Touch
R The camera's [Sensor selection] setting is set to [Off] (not make
detections).
→ Set [Sensor selection] to a setting other than [Off].
Motion detection/heat sensor
R The sensors do not operate when [Sensor selection] is set to [Off] or
[External sensor only].
→ Check the settings.
Motion detection does not work
R Motion detection does not operate at night when [Motion detection] is
set to [Day only].
→ Check the settings.
R Detections may not be made when the object makes small
movements.
→ Change the [Motion detection sensitivity] setting to a higher
sensitivity.
R Detections are hard to make when it is dark.
→ Use the heat sensor for detections or install lights to illuminate the
area around the object.
Heat sensor does not work
R The heat sensor does not operate at midday when [Heat sensor
detection] is set to [Night only].
→ Check the settings.
R Detections may not be made in the following situations.
– when reflective objects are in front of the camera and can interfere
with the heat detection, such as glass
– when snow is on the surface of the heat sensor
– when people move towards the front of the camera
R When the outside temperature is close to the body temperature, it is
hard to make detections. It is also hard to make detections when
people wear thick clothes.
→ Change the [Heat sensor sensitivity] setting to a higher sensitivity.
