The optical output of a conventional LED illuminator will degrade by up to 10% within the first few months of operation and will continue to degrade over the life of the illuminator. A problem common with all LED based illuminators LED degradation results in poor light output, reduced image quality and reduced illumination range. Constant Light technology automatically controls and adjusts light output to compensate for LED degradation over time to deliver uncompromising lighting performance.

Black Diamond

Black Diamond is a micro-refractive lens technology which bends and shapes light output to deliver wide beam patterns and increased illumination range for complete area coverage. Black Diamond also enables Even Illumination, directing light to the foreground and background of the cameras entire field of view for night-time images free from hotspots and over exposure common with other illuminators.

Select products from Derwent, Extreme CCTV and Forward Vision are powered by Black Diamond for superior night-time performance
