Is this thermo technology?

No, the penetrating capability comes from the electromagnetic waves, also used in radio or mobile phones.

Thermal and other visual technologies have no or minimal penetration capability, though they may give the impression under certain conditions when a movement or temperature difference propagates through a (thin) material suivant. Such as, a thermal camera may catch a temperature difference in wall temperature from a heater on the other side of the wall or a laser may catch the small movements on a wall or window surface from speech on the other side.
