Infrared Lens can See Through Clothes

KAYA PF4 lens attached to Sony NightShot 0Lux X-ray Video Camera can see through clothes, and here is the experiment

Here you can see a card with Kaya company name printed on it.



They place the card behind the cloth.



The card is effectively hidden by the cloth. It can't be seen by the human eye, nor by a standard camera.



They attach the KAYA PF4 to the camera lens..



..and now the card is clearly visible through the cloth!
