9.2.1 Image Adjustment (Thermal Channel)
You can optimize the image display effect of thermal channel by setting background correction
and manual correction.
Background Correction
Fully cover the lens with an object of uniform temperature in front of the lens, such as foam
board or paperboard. When you click Correct, the device will take the uniform object as the
standard and optimize the image once.
Manual Correction
Click Correct to optimize the image once.
Note
It is a normal phenomenon that short video freezing might occur during the process of
Background Correction and Manual Correction.
Thermal AGC Mode
Choose the AGC mode according to different scenes to balance and improve the image quality.
● Histogram: Choose for scene with obvious WDR and high temperature difference, can
improve image contrast and enhance image. E.g. the scene contains both indoor and outdoor
scenes.
● Linear: Choose for scene with low temperature difference and the target is not obvious, can
improve image contrast and enhance image. E.g. the bird in forest.
● Self-Adaptive: Choose AGC mode automatically according to current scene.
9.2.2 DNR
Digital Noise Reduction is used to reduce the image noise and improve the image quality. Normal
and Expert modes are selectable.
Normal
Set the DNR level to control the noise reduction degree. The higher level means stronger
reduction degree.
Expert
Set the DNR level for both space DNR and time DNR to control the noise reduction degree. The
higher level means stronger reduction degree.
