We are often asked :
‘what is the performance difference between 850nm and 940nm Infra-Red lighting?’
We answer your question with this video. All cameras are most sensitive to 850nm Infra-Red, 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.
