Dahua Camera / Interference (waves) when LED lights come on.. (video links)

[Cronus 0]

I have a 21 camera setup (Dahua A511K02 Lite Series HDCVI 5MP), all cameras are crystal clear in daytime.

At night, when LED flood lights come on, (4 out of 5) parking lot cameras have waving interference lines.

Of the 4 cameras, some see the LED light and some don't.. same interference on all 4.

How can i remove this interference?

Video links, with and without flood lights on..

Check if the camera is pal or ntsc, waves happen when the refresh rate of the camera is out of sync with the transmission frequency of the power grid.
