You want IR at night?
I am in pretty well the same position as you seem to be. So I bought one 5442T-ZE to check out cam install locations. I then realized that in some locations, something else may work better. So I did buy one 5442 LED-S2 cam to check lit locations.
I'd say it is difficult to judge without knowing your situation. You might get more experienced feedback from the experts here if you provide more info.
