Vision up to 39 is any Passive or Active IR system short of Thermal Imaging.
40 is Thermal Imaging (see through smoke).
50 and up is radar systems (Ground Surveillance Radar).

I was looking for something more in-depth than Mobhack help but thank-you for bringing that to my attention, I must have overlooked that aspect.
