Thread: Night vision 850nm vs 940nm

They do not see the 940, the real difference in performance is not that great until you get out to around 250 to 300m and more. I am talking about good quality VCEL IR lights, some LED's are Ok but they tend to be quite bulky and heavy. These days I tend to use the built in 940 on my unit and then I have an external 850 IR which I can turn on for longer ranges, this system seems to work well.

Thanks any chance you can send me a pic or details of what your setup is? sounds like a good way to go having both
