Not familiar with reolink but ghosting at night sounds like a power/ cabling issue
colour vu wont be any better if the cabling is the issue.
I supplied someone once with some analogue colour vu, they didn't want an installer to charge for fitting. however when the night image was shocking and it was shocking they asked for us to come out, the problem was the cheap and nasty super thin cable being used from the previous swann system, cable upgraded and correctly terminated picture was fantastic day and night.
my suppliers don't supply to general public unfortunately.
You don't say whether you want analogue (shotgun style), poc style, poe style or what resolution or what colour casing and so on.
Can you be more specific?
