Please read the following information about the camera’s motion detection sensor and heat sensor before deciding
where to mount the camera.
Sensor characteristics and detection range
Motion detection sensor Heat sensor
Detection method The camera detects changes in the images
being displayed.
R The camera detects changes in the
brightness levels of moving objects.
The camera detects temperature
differences of objects in the images being
displayed.
R The heat sensor uses infrared rays to
detect temperature differences within its
range that are emitted naturally by
people, animals, etc.
Main
characteristics Easily detects movement in the daytime or
when it is bright.
R Movement may be incorrectly detected
when the moving object and the
background have a similar colour.
R Movement may be incorrectly detected
when there are sudden changes to the
overall brightness levels such as when
external lights are used.
Easily detects when there is a big difference
between the temperatures of objects and the
surrounding environment, such as in winter
or late at night.
R The sensor cannot easily detect when
there is no difference between the
temperatures of objects and the
surrounding environment, such as in
summer or during the daytime.
R If the camera is mounted facing a road,
the sensor may detect incorrectly due to
interference caused by the heat from
passing cars.
