2.Detection concerns
They may fail to detect successfully if a heat source other than a human
being is detected or if there are no temperature changes in or movement of
a heat source. Care must generally be taken in the following cases.
The performance and reliability of the sensors must be checked out under
conditions of actual use.

3.Installation Suggestion
Definition:
O - the height of object
H - the height of sensor
from the ground
D - the distance between
object and sensor
Formula:
H - O / 2
D - O x 2
For example: To film a man at 180cm height in the video, the sensor
should be placed at 90cm height above the ground and the man is 3.6m
away from the sensor.

<1>Cases where a heat source other than a human being is detected
(1) When a small animal enters the detection range.
(2) When the sensor is directly exposed to sunlight, a vehicle’s
headlights, an incandescent light or some other source or far
infrared rays.
(3) When the temperature inside the detection range has changed
suddenly due to the entry of cold or warm air from an
air-conditioning or heating unit, water vapor from a humidifier, etc.
<2>Cases where it is difficult to detect the heat source.
(1) When an object made of glass acrylic or other subject which far
infrared rays have difficult passing through is located between
the sensor and what is to be detected.
(2) When the heat source inside the detection range hardly moves or
when is moves at high speed.
