Just found out that the Ubiquiti cam does not like LED light (green tinge).
The HDW5231R-Z does not have that problem.

Dahua vs Ubiquiti IR mode - Ubiquiti does not like LED light

Interesting.....have you tried different refresh rates on the monitor?
Is it safe to assume this is just a curious observation and not creating a problem for you?

Its a observation and only a problem because i know now that others like Dahua do not look like that 
I ask at the Ubiquiti forum and its normal with there cams - if somebody with a LED flashlight passes by it's green...
For a cam that cost ~ $230 if you also by the LED IR Range Extender ($160 + $70) i think the picture quality is not great compared to Dahua.
They only look good and have a big WAF.

I understand the importance of WAF.
But if they look like that with any IR floodlight, that would be a deal-breaker for me.

Oh, I knew that...
Not sure why I said IR; maybe because I was reading another post about a stuck IR filter in a camera. Time for a nap.
You posed that question or someone already said "...if somebody with a LED flashlight passes by it's green" ?
If that's the case, I wonder about LED auto lights, my LED outdoor floods, etc. and I don't think I'd care for that departure from "the norm".
The top image you posted, the camera is in color mode (thus the colors). The bottom picture is in Black and White (thus the gray scales). Put the Ubiquiti in B/W mode or force the 5231 into color mode to compare.
@TonyR, i thought the Ubiquiti cam is maybe broken and that's the reason i ask them.
The answer was: "All of my G3 cams see LED lights as green. They are not faulty. I turned on my yard light and took a screenshot."
And in his screenshot where his yard light is the snow is green.
@usaf_pride, it is in IR/BW mode.
This is color mode:
And this is BW without my ceiling LED lamp on:

VERY strange.....I've heard of "yellow snow" and would not care for "green snow".
I have them now outside.
The Ubiquiti already switched to IR while the Dahua did it 7 minutes later.
On the Ubiquiti the sensitivity is low and on the Dahua middle.
As you can see on the Ubiquiti the green leaves are rose, the garage is still yellow and the car is still red:
The Dahua 7 minutes later:
And what the Dahua captured while the Ubiquiti already was in IR mode:
The Ubiquiti. IR from the Dahua is off. As you can see the light from the lamp in our window and the streetlamp behind the tree is green.

The IR filter on the ubiquiti looks like its stuck on. That is why you see the weird colors during the day.
Weird colors during the day?
Its not stuck. You here it switching and you see the difference between color and bw/IR mode.
Here are two images in both modes: Dahua vs Ubiquiti IR mode - Ubiquiti does not like LED light

What is actually happening is that it's not switching the IR cut filter is staying on, that is why the colors look like that... That is exactly what you would expect when the IR cut filter is stuck on but there is light. It may also only be partially stuck.
Interesting. When it comes to the color picture you posted where the green leaves were pink/rose tinted, I don't think it's even possible to manually set a Dahua camera to do that... you normally only see that when the ICR is physically stuck.
Remember it is not a color picture. Its Ubiquiti in night mode.
First time i saw that was on the Pi NoIR cam so i thought its normal - until i saw the Dahua.
Yes but that is after the sunrise. And then without filter its normal.
The Pi cams have no switchable filters and this is the NoIR cam.
But even at night you have green leaves in the front and rose trees in the back.
So its a mix of color and bw like the Ubiquiti.
I guess the Ubiquiti moves the filter away to early when there is still IR from the daylight.
But that does not explain the green tinge on lights.
This is the Ubiquiti only with its own IR lights:
Ubiquiti with its own IR lights plus the Dahua IR lights on:
