Are there cameras without an IR filter?

Question

Do it yourself

Good time!
On all cameras now there is a light filter in front of the matrix (or somewhere else) to remove light in the red and ultraviolet ranges. I need to see what happens beyond 880 nanometers up. while the visible (human) range is not important to me. Are there cameras tailored for this spectrum?
I tried to pull the filter out of the phone, most likely it would have worked, but the camera module broke down (
There is an article on Habré, "We look at the world through the eyes of a mantis shrimp: near inf ... , in which the author showed what is happening in the near range. Who Does anyone know something similar?It is desirable that the camera work in this range initially, and not after tearing out the
glass.Thank you all!

Answer 1

Ocelot is correct about night vision cameras. But keep in mind that cameras work mainly with 850nm. If 950nm floodlights are used, the detection range is reduced by about half. Sample result https://youtu.be/5u8228Nk6KM . Accordingly, I recommend taking this into account.
Well, the camera summarizes what it sees in the IR and visible range.

Answer 2

Surveillance cameras sharpened for night shooting. They have an IR filter removed when you turn on the night mode.
