Smart Illumination, how does it work?

[arman1201]

Hi all,
I'm having an issue with smart illumination
Cam is HDW3849H-AS-PV-ANZ
NVR is NVR4108-8P-AI-ANZ

The cam has a smart illumination mode which I am using under AUTO
The cam is facing the front driveway which has a street light on the other side of the road.
At night normally it'll just have IR on although it does have ambient light from the street light.

I've got IVS setup so it'll trigger when someone walks up the driveway
My understanding is that the white light should turn on as well as the deterrent light if armed. That's whats happening with another cam, although in a much darker spot
Unless the white light turns on ONLY when there isn't enough light to capture color video? (in this case the camera believes the ambient light from the street light is enough?)
If so is it possible to force the white light to turn on when it detects under IVS in low light conditions?

Basically I'm trying to use it as a flood light.
Normally I have the deterrent light and alarm disabled (on a schedule) until later in the night

Thanks!

Based on my own experiences: the white light is independent of the IVS settings. So it is perfectly possible that there is an IVS trigger but the white light does not switch on. If the camera in IR or colour mode detects a person anywhere on the screen and it is dark enough, it turns on the white light. I see that your delay is set to 60 seconds. Isn't that too long? It seems perfectly possible in your situation for someone to walk from the street to your house in less than 60 seconds. Then your light won't turns on.

I have noticed that in the latest firmwares versions, the light also turns on for cars. You also have new functions to set time slots when the light should not turn on etc.

I also notice that the smart illumination turns on more when choosing Color in the day/night option.
