Problem
Cause & Solution
Page
The sub monitor, the AC
adaptor, or the charger is
warm.
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.

Camera (sensor operations)
Problem
Cause & Solution
Page
Monitoring can be
performed with the
camera but sensor
notifications are not
received.
R
The camera (sensor detection) is turned off.
→ Touch
®
Off
On
.
R
The camera’s [Sensor selection] setting is set to [Off] (not make
detections).
→ Set [Sensor selection] to a setting other than [Off].
Sensors do not make
detections.
R
The motion detection
and heat sensor do
not work
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.
