03 / Imaging capabilities

01 / 4K UHD

More image detail

3840 × 2160 resolution provides four times the pixel count of 1080p. At the same field of view, a matched imaging system can capture more target detail.

02 / NIR IMAGING

Imaging in haze

Near-infrared imaging for improved visibility in haze.

03 / ZOOM & FOCUS

Focus retained while zooming

After initial focus, focus retention during zoom reduces refocusing. Autofocus and motorized focus are also supported. Changes in distance or conditions may require focus adjustment.
