Color balance won't have any effect; the camera is in B/W mode. I've already tried adjusting that previously with no effect.I'm guessing the same way that a piddly led flashlight can reflect off a sign that far away but clearly isn't providing enough light to be effective at that distance.
I guess we need to investigate the IR on cameras because from the street the red glow of a bullet looks the same as that of a turret,but the bullet range is further. Is it strictly a wattage thing or is there something we are missing that is flawing the 730nm option.
Probably wouldn't make a difference, but what about b/w with I think it is called the electrical option (I think it is electrical and ICF or something like that as two options) and see if that picks it up?
Or if you can see the red reflection, what about adjusting the red on the color balance?
Just brainstorming ideas to try to make it work.
My best guess at this point is that the beam angle from the IR LEDs needs to be much narrower. Consider that in a bullet camera the LEDs will point in the same direction as the lens, so precise alignment with a narrow beam angle is automatic. I'm now wondering if I should have specified 10 degrees instead of 30 degrees. Yet professional illuminators provide a wide range of available beam angles at similar power levels. So ... do professional illuminators use different IR diode emitters?
