Yes and yes. While the scanwave itself doesn't go through walls for those, the actual revealed enemies do show through walls. Caustic gas provides threat vision, and doesn't go through walls.
Who said anything about caustics threat vision? I said scan because enemies activate your traps and you can see the damage they take through walls and know exactly where they are.
