Yes, there are NoIR versions of v1 camera, they just miss the infrared filter normal cameras have (around 9$ on aliexpress.com). And there are 12$ versions of v1 camera with (hardware) IR-cut filter, depending on photo sensor on camera IR filter is enabled at day, and removed at night.

I was wrong, the 9$ are for NoIR camera with M12 lens mount and lens. I just ordered 4 new NoIR cameras for 2.84$(!) including shipping! https://www.aliexpress.com/item/32946093276.html
