My 0.02 ... not working great for me.
Not sure if this is something SmartIR could even resolve for me, but I have a 5442 cam on a dark driveway with a car typically parked in it. The front LP reflects the IR a lot and causes the rest of the scene to be affected negatively. No IR is too dark, and way too dark for color.
I'm sure the best solution is IR mounted somewhere away from the camera, but i don't want to do that.
