Solutions with Backlight

In extreme backlight situations – for instances in entrance areas where objects in dark areas are barely recognisable – two technologies offer themselves: a progressive scan CCD with WDR functionality or a Pixim CMOS sensor.


Camera with out WDR or Pixim



Camera with a dynamic range


WDR (Wide Dynamic Range) function
Wide dynamic range considerably increases the dynamic range of the camera so that details are clearly identifiable in dark and bright areas of the picture. This is achieved by exposing the entire image over a long time and evaluating the results. The camera then automatically selects each optimally exposed image section from these different exposure phases. The overall picture is then put together from these individual images. Persons or objects in shaded areas no longer disappear in the darkness with the bright areas in the picture simultaneously being unrecognisable.


Digital Pixel System
The patented Digital Pixel System® technology (DPS®) enables hundreds of thousands of pixels to act in the same way as continuously self-regulating single cameras. As opposed to conventional camera technology that digitalises pictures only after completion of a series of processes, the picture is digitalised immediately with (DPS®) technology. This is made possible by the integration of an A/D converter (analogue to digital) on each and every pixel of the sensor. The chip can therefore assign an optimal illumination time to each individual pixel.
