HGH Infrared Systems, manufacturers of advanced infrared cameras and a variety of thermal imaging products and systems, introduced the new IR Revolution 360, a 20° vertical, 360° horizontal field of view (FOV) panoramic infrared vision system for security and surveillance.

The revolutionary sensor contains approx. 3 million pixels (10,000 x 288). This advanced thermal imager delivers clear, extremely high resolution imagery via the rotating head that scans a full 360-degree rotation per second. Other features include auto detection and tracking, a motion alarm, and an area-of-interest zoom.

The detector is based on mercury cadmium telluride (HgCdTe) imaging technology and operates in the 8 -12 micron wavelength, the long-wave infrared (LWIR) region. The high sensitivity (<25 mK) IR camera detection range, without image distortion, is up to 1 kilometer (km) for a human figure, up to 1.5 km for an automobile, and up to 6 km for a boat or ship.
