DH-IPC-HDW3849H-AS-PV-PRO Illimunator toggle not working

[maxiride]

I've tested the integration with a DH-IPC-HDW3849H-AS-PV-PRO, everything seems to work fine except for the Illuminator toggle.

I have the camera configured as follow. As-is the white floodlight is off and at night the camera goes to IR mode, if human presence is detected and conditions are met the illuminator turns on.

My understanding of the HA toggle is: forcefully turn on white floodlight. However nothing happens when turning the toggle.

Debug logs seem to show everything is OK, either my understanding is wrong or the logs aren't logging correctly.

I am just exploring around to further understand the situation, I retrieved the v3 API spec and calling {{BASE_URL}}/cgi-bin/configManager.cgi?action=getConfig&name=Lighting returns the following capabilities:

table.Lighting[0][0].Correction=50
table.Lighting[0][0].MiddleLight[0].Angle=50
table.Lighting[0][0].MiddleLight[0].Light=50
table.Lighting[0][0].MiddleLight[1].Angle=50
table.Lighting[0][0].MiddleLight[1].Light=50
table.Lighting[0][0].Mode=Auto
table.Lighting[0][0].Sensitive=3
table.Lighting[0][1].Correction=50
table.Lighting[0][1].MiddleLight[1].Angle=50
table.Lighting[0][1].MiddleLight[1].Light=50
table.Lighting[0][1].Mode=Auto
table.Lighting[0][1].Sensitive=3
table.Lighting[0][2].Correction=50
table.Lighting[0][2].MiddleLight[1].Angle=50
table.Lighting[0][2].MiddleLight[1].Light=50
table.Lighting[0][2].Mode=Auto
table.Lighting[0][2].Sensitive=3
table.Lighting[0][3].Correction=50
table.Lighting[0][3].MiddleLight[1].Angle=50
table.Lighting[0][3].MiddleLight[1].Light=39
table.Lighting[0][3].Mode=Off
table.Lighting[0][3].Sensitive=3

From the debug logs I can see the HA integration calls /cgi-bin/configManager.cgi?action=setConfig&Lighting_V2[0][2][0].Mode=Off&Lighting_V2[0][2][0].MiddleLight[0].Light=39 but I can't find the Lighting_V2 documented anywhere, is there a more updated API spec?
