As you already know, the Strike Force 850 is the red glow trail camera. The 850 refers to the IR nm light spectrum. So this camera has 850 nm (or what we refer to as red glow).
We have begun testing, should have results posted throughout the next several business days.
The 940 in the name "Browning Dark Ops 940 HD" refers to the nanometers once again. Anything 935ish and above the human eye can't see.
