Iscon's patented, thermo-conductive technology combines infrared (IR) and heat transfer, for high-resolution imaging without using any radiation. The patented technology works by breaking the thermal balance of an object being hidden under clothes by the combined use of preheating and an IR camera.
There are no privacy issues with Iscon technology. Infra-red rays cannot penetrate through clothes. What the camera sees is the thermal imprint of the concealed object against the clothes.
