In most cases, thermal has the advantage for first-pass awareness when visible light is poor. But that does not mean thermal fully replaces visible imaging, because low-light performance is only one part of the surveillance task.</p> <p>Thermal and visible cameras are often grouped together as &ldquo;optical&rdquo; surveillance, but they do not observe the same thing. A visible camera depends mainly on reflected light in the visible range. A thermal camera works from infrared radiation and heat-related contrast.</p>
