850nm vs. 940nm Infra-Red Lighting

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 surveillance footage at night. 940nm delivers virtually invisible covert lighting but does result in reduced performance (typically up to 40% less) and requires a very sensitive camera.

Here we take a high performance camera and see how it performs with 850nm and 940nm.
