How to select a night vision mode?
“There are two night vision modes: automatic switch according to the light
environment and white light-assisted lighting.
Automatic switch according to the light environment: fit for a scenario without ambient lighting (and undesirable to turn on the white light frequently) When this mode is enabled, it will be displayed in black and white without light source, and the infrared light will be turned on when the mobile detection is triggered, so as to enhance the night vision effect.
White light-assisted lighting: fit for a scenario with other always-on light source. After this mode is enabled, it will be colorful display, and the white light will be turned on when the mobile detection is triggered, so as to fill light.”
