We are often asked :
‘what is the performance difference between 850nm and 940nm InfraRed lighting?’
We answer your question with this video. All cameras are most sensitive to 850nm InfraRed, delivering superior CCTV or night vision at night. While 940nm delivers nearly virtually invisible covert lighting but does result in reduced performance (typically 30% to 40% less) and requires a very sensitive camera.
Here we see how it performs with 850nm and 940nm, and hope this video can be helpful for you when choosing night vision products.
