The advantages of SWIR are not very obvious. Yes. it gives a slightly better penetration ability during the day in the haze, but for these tasks you can use CMOS sensor together with IR Pass filter 900um. At the same time, we have a significantly higher resolution and a lower cost of the camera. SWIR is good in rain or snow, it also sees well at night (however SWIR cameras are not all manufacturers see at night). Also due to the greater depth of the quantum well, SWIR can see the stars during the day.
