Abstract
An apparatus for discreet imaging of a scene, comprising: at least one short wave infrared (SWIR) sensor that captures at least one SWIR image of the scene at a SWIR wavelength range, at least one SWIR illumination element that generates SWIR illumination at the SWIR wavelength range, and a barrier positioned such that SWIR illumination reflecting off objects of scene within the field of view passes through the barrier to reach the at least one SWIR sensor, the barrier made out of a material and having a thickness selected for being opaque to visible light and non-opaque to the SWIR wavelength range.
