Empiretech Color4m-T: prevent white light on human detection via API (Lighting_V2 / AI mode confusion)

[pol]

I’m trying to fully control a Dahua camera via API, specifically to disable the white light when a person is detected at night, while still keeping IR working.
Current setup:

• Web UI:
  • Customized Scene is selected
  • Day/Night profiles are configured
• API:
  • Switching day/night profile works correctly
  • Changing backlight mode (WDR/HLC/etc.) works
  • Changing lighting mode (Smart / IR / etc.) works

Questions​

1) Scene selection
Is it correct to use “Customized Scene”, or does this interfere with API control of lighting behavior?

2) How to disable white light on human detection?
Goal:

• At night → IR only
• Never trigger white light, even if AI detects a person

What I’ve tried:

• Setting LightingScheme[0][0].LightingMode=InfraredMode
• Setting Lighting_V2[0][1][1].Mode=Off

I've seen that there is a table.Lighting_V2[0][1][2].AIMixLightObjFilterTypes[0]=Human but I cannot find a way to play with it. The Mode doesn't accept Off, so that's ruled out.

I've tried setting

table.Lighting_V2[0][1][0].Correction=50
table.Lighting_V2[0][1][0].LightType=InfraredLight
table.Lighting_V2[0][1][0].MiddleLight[0].Angle=50
table.Lighting_V2[0][1][0].MiddleLight[0].Light=50
table.Lighting_V2[0][1][0].Mode=Auto
table.Lighting_V2[0][1][0].PercentOfMaxBrightness=100
table.Lighting_V2[0][1][0].Sensitive=3
table.Lighting_V2[0][1][1].Correction=50
table.Lighting_V2[0][1][1].LightType=WhiteLight
table.Lighting_V2[0][1][1].MiddleLight[0].Angle=50
table.Lighting_V2[0][1][1].MiddleLight[0].Light=50
table.Lighting_V2[0][1][1].Mode=Off
table.Lighting_V2[0][1][1].PercentOfMaxBrightness=100
table.Lighting_V2[0][1][1].Sensitive=3
table.Lighting_V2[0][1][2].AIMixLightObjFilterTypes[0]=Human
table.Lighting_V2[0][1][2].AIMixLightSwitchDelay=60
table.Lighting_V2[0][1][2].Correction=50
table.Lighting_V2[0][1][2].LightType=AIMixLight
table.Lighting_V2[0][1][2].Mode=Off
table.Lighting_V2[0][1][2].PercentOfMaxBrightness=100
table.Lighting_V2[0][1][2].Sensitive=3

and also

table.LightingScheme[0][1].LightingMode=InfraredMode
table.LightingScheme[0][1].SchemeSchedule.Enable=false
table.LightingScheme[0][1].SchemeSchedule.TimeSectionByWeek[0][0]=00:00:00-23:59:59 AIMode
table.LightingScheme[0][1].SchemeSchedule.TimeSectionByWeek[1][0]=00:00:00-23:59:59 AIMode
table.LightingScheme[0][1].SchemeSchedule.TimeSectionByWeek[2][0]=00:00:00-23:59:59 AIMode
table.LightingScheme[0][1].SchemeSchedule.TimeSectionByWeek[3][0]=00:00:00-23:59:59 AIMode
table.LightingScheme[0][1].SchemeSchedule.TimeSectionByWeek[4][0]=00:00:00-23:59:59 AIMode
table.LightingScheme[0][1].SchemeSchedule.TimeSectionByWeek[5][0]=00:00:00-23:59:59 AIMode
table.LightingScheme[0][1].SchemeSchedule.TimeSectionByWeek[6][0]=00:00:00-23:59:59 AIMode

but still that damn white light is turning on when a human is detected
