A known problem inherent in surveillance and other observation systems is the need to overcome visibility reducing conditions such as: humidity, haze, fog, mist, smoke, dust, snow or rain that might be present in the space between the surveillance system and the target being observed. The particles or droplets reduces visibility in two ways; the first is the actual obscuring of what is behind the particle, and the other is the effect called “light scattering” caused by light reflection in the particles.
Both these effects increase with distance, especially when zooming in on a distant object. Even on what appears to be a fine and clear day, there will most certainly be enough haze or fog in the air to reduce contrast significantly.
Also, telephoto lenses have a narrow field of view, allowing bright light outside your image area to affect your image with flare, which reduces contrast.
All these effects are drastically reduced with LYYN products.
