hi guys, thinking about upgrading my system which I have present, looking for one with colour night time vison, could you recommend me with some products please tia

To get colour image, you need light.
CCTV cameras today are much more sensitive than before.
Check the cameras spec for amount of lux.
Lower lux means darker it can see.

But still, you either switch to black/white at night and most cases use IR light to enhance B/W image, or you add white light to get colour images.

hi there I understand about the luz, at present I have an old swann set up, I was looking at an lorex one, but the one I seen was usa only plus not pal, what good system i.e. with colour vision in the uk please

You have to choose the best security system with all those latest features useful to get your home safe like HD cameras, monitoring on smartphone etc https://northernlights.co.nz
