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.
