Camera board • Re: Ir vs normal camera

The camera module is sensitive to IR as well as normal light. The standard camera has a filter to block the IR. The NoIR camera does not have that filter - hence the name No IR (filter).

The sensitivity graphs in https://datasheets.raspberrypi.com/came ... tivity.pdf give the data behind it for HQ and GS cameras.
v2 is on page 87 of https://raw.githubusercontent.com/relli ... et_XXX.PDF.
v3 is similar, but I can't find the graph immediately.

In all cases the pixels still have significant sensitivity at the IR wavelengths, so dropping the IR filter allows for IR illuminated scenes.

I believe the NoIR camera about because people were taking the IR filter off the standard camera to use for various projects.

Correct - https://www.raspberrypi.com/news/infrar ... you-asked/
