Measurement Field of View of Infrared Thermal Sensor
The measurement field of view of an infrared thermal sensor is made of the following elements.
With one segment as 8 pixels × 8 pixels, the measurement field of view is made of 16 segments per
infrared thermal sensor.

Infrared thermal sensor
In the Main Unit, the alarm threshold is set in the "segment" unit rather than the pixel unit or the infrared
thermal sensor unit, and alarm determination is performed.
