How To Assess Thermal Camera Range For Site Design
How To Assess Thermal Camera Range For Site Design When laying out a site design for surveillance using currently marketed uncooled thermal cameras, it is important to understand the coverage capability of the cameras under evaluation in terms of field of view and range. Accurately gauging range performance from the onset of the site design may allow one to avoid unintended and pricey rework costs later. The following white paper explores the various determinants that are needed for thermal...  Continue Reading...
