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 CCTV 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
