You would have thought yes.
But obviously has some sort of detection, as I set up trip wire and had the red and blue leds and siren working with movement, I would have thought that would link to turning on and off the white led with movement as well
In that version the white light isn't linked to any AI features.
It should be a simple turns on when the light level is too low for a colour image.
FYI even the newer TiOC 2.0 the light is triggered depending on the motion detection / SMD zone, not the IVS rules.

Thanks again mate, was doing my head in trying to.work it out, never occurred to me that it didn't have that feature being a new 4k camera, ahh well least it wasn't user / installer error. Have a good one
Sadly, you have fallen for the chasing MP trap. Are you able to return them?
You want cameras with MP/sensors in GREEN.
Most here will say that 4MP is the sweet spot for these types of cameras.
See this thread for the commonly recommended cameras (along with Amazon links) based on distance to IDENTIFY that represent the overall best value in terms of price and performance day and night.
The Importance of Focal Length over MP in camera selection
Unfortunately your camera is an active deterrence camera on an 8MP on a 1/2.8" sensor, so it is on a horrible MP/sensor ratio. You cannot have enough light at night for it to perform well. That sensor is designed for 2MP so a 2MP camera will kick its butt all night long.
Even worse, since this 8MP is on the same sensor and CPU as a 2MP non TIOC camera and there are many threads here showing how under-performing that 3849 is. They had to limit bitrate and other parameters on the 3849 to try to make it functional, and it just doesn't cut it.
This is what happens when someone chases MP over sensor and this camera is the epitome of that thinking.
Further, the red/blue flashing lights are more gimmicky and are certainly not a deterrent. With any ambient light you won't see the red/blue flashing unless you are looking right at the camera.
If you want active deterrence, your best bet is to go with the 2MP IPC-T5241H-AS-PV that will blink the white light. This is on the ideal MP/sensor ratio and will perform comparably to any similar 2MP fixed lens camera by Dahua. I have two of them. I have some of the other active deterrence cams as well, and would opt for the 2MP in every instance except for indoor, one could go with the IPC-HDW3449HP-AS-PV that has the red/blue lights that will bounce off the walls and be much more impressive than outside.
Lot's of threads here where people showed how bad the 3849 camera is in performing:
IPC-HDW3849H-AS-PV issues
IPC-HDW3849H-AS-PV loses connection/reboots during the day
Replaced HDW5442TMP-ASE by HFW3849T1P
Dahua 8mp (TIOC): Full Colour, Active Deterrence & AI
IPC-HDW3849H-AS-PV Video Quality

Thanks for the informative reply, I took a look at the links you added as well, pretty well sums it upSadly, you have fallen for the chasing MP trap. Are you able to return them?

I had read about the trap of chasing higher MP so probably should have known better but was thinking with a motion activated LED for additional light I may be able to live with the reduced night performance v better day light image for my situation, but having the LED on continuously at night was not what I was expecting.
Why the hell isn't the LED motion activated, makes no sense?
My 5MP cams do a pretty good job both in daylight and at night with IR and motion activated white LED,
I will look at your recommendations and the MP v sensor chart you added and replace these 4K units, which alas I can't return. Mayb I can find a use for them elsewhere! Dammit.
Thanks again appreciated
