Hello,
I have several original HDW (T5442) and some Chinese HDW (4631C, 6238X) in place.
For my understanding the T5442 is using by night an IR light which is not visible by night, correct ?
Have no idea which IR light the 4631 is using.
However, can I add an additional IR light for the T5422 ?
Which wavelength is used for the T5442?
Does this makes any sense?
Any hint is welcome.
