Vayu HD

Stunning 1920 x 1200 HD Thermal Imagery

Featuring the world's first full 1920 x 1200 12 μm uncooled VOX microbolometer array, the Vayu HD is the industry gold standard for critical applications when superior imaging performance at the lowest weight and the highest resolution available are essential.


With true 1920x1200 (Full HD) resolution from an uncooled VOx microbolometer array, the Vayu HD is the highest-resolution LWIR camera on the market. At just 450 and 520 grams (25 and 50mm lens versions) and compact enough to fit in the palm of your hand, the Vayu HD sets a new standard for superior image quality and resoltuion in a compact, SWaP optimized package. 

The camera features a USB3.0 raw video output for more universal compatibility, an open chassis for the lightest possible integration weight and an F/1.2 lens with a high-durability AR coating for calibrated optical performance. An onboard image processor provides H.264/H.265 encoded RTP output, advanced image processing functions, and the ability to implement optional features such as object tracking and detection with telemetry, NMEA metadata packaging and more.
