You will need a reflector on the other side of the corridor to bounce the IR off. It needs to be modulated but most of the IR receiver chips are meant for data not this sort of light barrier stuff.

WebNo, thermal cameras cannot see through walls, at least not like in the movies. Walls are generally thick enough—and insulated enough—to block any infrared radiation from the other side. If you point a thermal camera at a wall, it will detect heat from the wall , not what’s behind it. However, if something inside the wall causes enough of ...

WebNo, infrared radiation does not go through glass. Infrared radiation is a type of electromagnetic radiation, and glass is essentially opaque to all types of electromagnetic radiation. This is because glass is made mostly of silicon dioxide molecules which have a strong interaction with electromagnetic radiation. WebThe device is measuring the incoming infrared radiation emitted from the object in the direction of the laser. Just because glass is transparent doesn't mean it doesn't emit infrared. So you are taking the temperature of the glass. That said, infrared can somewhat go through glass, not as easily as visible though.
