"The Falcon Eye cameras do not work with IR illumination or an image intensifier unit as most night vision equipment does.
The Falcon Eye cameras are build with a new type of CMOS sensor and combined with the advanced electronics and image controlling software it has been possible to create this unique system with a light sensitivity way beyond what other night vision systems can deliver.
The proprietary KClux CMOS sensor and KCnoise 2D/3D noise reduction technologies are the secrets behind the revolutionary KC-2000 cameras.
High quality viewing, video recording and photo capturing during day and night with ISO 2,000,000. Can even record through dark tinted glass.
All parts 100% designed, manufactured and assembled in Japan including sensor, housing, and optics."
