Does the red glow from the infrared emitters spook or cause alarm in game animals and more particular deer? Don't ask me how they came up with this one but one theory I've heard is deer are skittish around the cameras that have the IR because they associate the red glow supposedly to predators eyes.
Is there a filter you can put over the IR emitters so game animals won't see them? Do the filters cut down on the effectiveness of the emitters? I seen on one of the reviews for the Scoutguard SG550V there was a picture of one with a filter, does anyone know if this in fact was a filter to cut down on this glow and if so do you know where to get these filters?
