System Presets
Certain functions of the camera that are not defined by the
Pelco-D Protocol are called by using Presets. A list of System
Presets can be obtained by contacting Iris.
Camera Calibration
Although the thermal camera core automatically calibrates itself
every couple of minutes, from time to time, especially in hot
temperatures or in conditions of low thermal contrast it may be
desirable or necessary to perform a manual calibration.
There are two levels of manual calibration available, called
Passive or Active:
Passive:
Also referred to as NUC ʼ ing (pronounced nuking), this is the
standard method of calibration. Usually required in low thermal
contrast conditions.
Active:
Active calibration can be used to improve the image if the
camera temperature is high. Once selected, the camera will tilt
down into it
ʼ s standby position and operate it ʼ s shutter. This
calibrates the thermal sensor to a ʻ flat ʼ external image. Once the
shutter has operated the camera will tilt back up to it ʼ s previous
tilt position.
To calibrate the camera select the desired function (PASS or
ACTV) from the SET menu.
