Devices like the AN/PPS-26 STTW can help you sense through the walls without using any superpowers. An acronym that roughly stands for 'Sense Through The Wall,' this handheld radar gadget does just that.
Created for military purposes, the AN/PPS-26 STTW device could help soldiers detect the presence of enemies before entering a building. Unfortunately, it can't hone in on size or composition, only motion. This means that it can't actually detect whether it is a person or not in movement. Nevertheless, this innovative gadget will definitely come in useful considering its abilities.
